METHOD FOR DETERMINING TOTAL COST OF OWNERSHIP
This invention generally relates to methods for calculating costs attributed to the use of computing equipment and services. In particular, this invention relates to the costs of providing and maintaining computing services and methods to analyze those costs.
The Total Cost of Ownership (TCO) is defined as the total, per-seat cost incurred across a technology organization through the provision of continuing computing services to its users. It has now become an important metric for Information Technology (IT) to its users and for the IT industry. Organizations can evaluate their TCO either by considering their overall budgets through a top- down or bottom up approach.
As many organizations are under pressure to reduce costs, including of course the TCO for Corporate Systems, vendors and industry observers have predicted various levels of cost savings associated with both technology (e.g., migration from client-server environments to net-centric environments) and • process improvements. Unfortunately most of the time their cost-savings claims do not provide the necessary context for decision makers to evaluate them, because the source of savings are not fully specified and the costs associated with the migration from one environment to another are not considered. Therefore, there is a need for an improved method for determining the TCO that provides a detailed analysis for decision makers.
SUMMARY OF THE INVENTION
In one embodiment, the invention includes a method for determining the cost per user of an information technology system. The method includes obtaining base costs, ongoing direct costs, and ongoing indirect costs. The method further includes gathering information relating to user profiles and organizational characteπstics. These costs and information are input mto a computer program to determine the cost for each user.
In a second embodiment, the invention includes a method for analyzing the costs associated with supporting an information technology system. The method includes obtaining cost information and system characteπstics. Appraisal metncs are calculated based on the cost information and system characteπstics. The metncs may be compared against established benchmarks.
This invention defines both metncs used to measure the costs associated with distributed computing when performing a TCO analysis, as well as metncs used to evaluate the operations effectiveness and efficiency Where possible, the metncs are referenced to IT organizational functions in order to define precisely potential added value.
One application of this invention is to provide a TCO framework aligned as far as possible with the Management of Distnbuted Environments (MODE) framework (an IT organizational framework commercially available from
Anderson Consulting, L.L.P., Chicago, Illinois, USA), so that the factors that contπbute to the TCO can be clearly identified and that the "Gap Analysis" could be done according to the MODE functions, which would allow to better assess
MODE'S added value. Of course, this invention is not limited to being earned out with a MODE framework, but can be applied withm other IT organizational frameworks.
Another useful aspect of this invention is a set of metrics that give a holistic view of the TCO. These metncs enable comparative studies and benchmarking, as well as assessing the impact of possible changes and determining improvement opportunities through MODE's best practices implementation.
BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE DRAWINGS
FIG 1 shows a representation of one embodiment of the method of the present invention DETAILED DESCRIPTION OF THE INVENTION
The TCO analysis becomes part of any Information Systems (IS) organization's continuous process of measurement, improvement and resource planning; it enables the simulation of improvement plans for asset changes, best practice implementation and complexity reductions
In order to perform the TCO analysis, a methodology is used that requires both a financial chart of account and appraisal metncs relative to the distnbuted environment.
The initial step is to categonze the costs according to the MODE framework, or any other IT organizational framework implemented m an enterpnse's IT systems. For illustration purposes, this mvention is descnbed m terms of the MODE framework However, the costs may be categorized according to the IT framework which is described in co-pending application No , entitled Organization of Information Technology Functions, by Dove et al . which was filed October 6, 2000, which is herein incorporated by reference. Once the costs have been categonzed, they have to be "standardized," l e., put under a format that allows one to compare the data elements with others and do benchmarking to depict typical values for each data element and metric
It is desirable to factor in key organizational and reference assumptions (e g - company size, number of computers, etc.) when considering benchmarks, and try to point out all the factors of influence that impact the costs Beyond asset and activity based costing, appraisal metrics will tally key staffing ratios, activity person hours, help desk performance metrics, and end user satisfaction metrics to provide the client with a complete perspective of its actual position and potential evolution
Benchmarks are considered to carry out a consistent evaluation of an enterprise's position that also give insight to improvement initiatives Actual and typical values for all the metrics and data elements, with all the relevant assumptions required to understand those values, are developed by experience in evaluating IT systems. The benchmarks are useful for an Opportunity/problem analysis.
Costs Categorization and Metrics Definition
In order to take into account the total costs associated with major investments and changes, BASE COSTS and ONGOING COSTS have been considered and have been adopted to categonze both one off investment and costs incurred through ongoing operations. Only the ONGOING COSTS will be aligned to the MODE framework, since MODE'S added value pnncipally lies m the potential changes that have to be made. The BASE COSTS measure the one off costs of implementing the base
System and Network Infrastructure. These costs consist of the planning costs (labor expenses), the acquisition costs (hardware and software purchase), which are typically Capital costs, and the installation costs (labor expenses).
The ONGOING COSTS measures the total amount of expense since the IT Infrastructure has been running. The costs are categoπzed as direct and indirect costs. The direct costs are the day-to-day operational costs such as maintenance, support, momtonng etc., whereas the indirect costs pertain to the unbudgeted costs that are caused either by downtime or end-user inefficiency at work The Direct Costs, that refers to the Ongoing expenses of running IT operations, are hard factual costs, whereas the Indirect costs are often related as "soft" costs, because they are more subjective (i.e., it is difficult to measure them in a consistent way).
Obviously there are many factors that influence the costs related m the previous categones. Those TCO Dnvers, like Enterpnse profile (industry or business type, world-wide geographic location, enterpnse size, end users type), Technology volume and type (servers, Client computers-mobiles + desktops- peπpherals, network), Management Practices (Technology, Process, People), Complexity (IS organization, IS processes and service, end-user organization, hardware and software) are "tuning" the average typical values collected in benchmarking databases. These factors must be related as assumptions when compaπng data in order not to come to wrong conclusions.
To avoid confusion and compare data more easily, often various parameters are gathered to compute a metπc. Cost metncs can be denved straight forwardly from the costs elements, when associating the costs to another quantities (number of employees, number of desktops, etc.), which allows one to compare the TCO of vanous companies without having to make conversions.
Metncs are also helpful to provide the decision makers with a holistic view of the TCO. There are not only quantitative metncs, but also qualitative metncs, that examine the global performance of a company, and tend to determine its profile. Several appraisal metncs are defined that are categonzed according to three different areas:
• Financial perspective (FP)-Thιs area looks at the organization in terms of its financial performance. • Ability to operate effectively and efficiently the IT Operations and Systems
Infrastructure (OEE)-Thιs area examines the system's performances.
• Infrastructure and evolution perspective (IEP)-Thιs area looks at the system's future and scalability.
For each metric developed, the appropnate MODE function is allocated. category referenced, the parameters descnbed, how to compute it (construction and formula) and possibly its benchmark. Then the different relations that exist between all the appraisal metncs are detailed in order to make their interpretation easier and thus allowing to perform a better opportunity study.
The TCO metncs are aimed at not only reporting the costs of a distnbuted environment, but also give a holistic view of its components. The first step is to measure the costs, and then to see where they stem from, identify the factors of influence for each cost areas, the correlation between the metncs. and try to assess the impacts of change (management, technology) withm the IT organization The completion of this step will allow for assessment of opportunities agamst different scenaπos. One embodiment of the method of the present mvention is represented m Figure 1. In this embodiment, a senes of cost data about a particular aspect of an information technology system is gathered. The cost data includes base costs (10), ongoing direct costs (12), and ongomg indirect costs (14), which are input into a cost data array (16). In addition, a senes of user profile and IT organization characteπstics are obtained. This information and characteπstics are used for calculating a senes of metncs. Financial charactenstics (18) are obtained and input mto the FP metncs array (24). Operating and efficiency charactenstics (20) are input into an OEE metncs array (26). Infrstructure and evolution charactenstics (22) are obtained and input mto an IEP metncs array (28) Specific cost information from the cost data array (16) is input mto the FP metncs array (24) and used for calculating certain FP metrics From the cost data array (16), the data is used to calculate cost information which is used to generate a summary report (30) of the total cost of ownership. The cost data and the metrics are used to generate functional category detail reports and benchmark analyses (32). These reports and analyses break down the cost information and appraisal metncs according to the IT organizational functional categones to which that information corresponds. For example, under a MODE functional organization, the cost detail and appraisal metncs are broken out and provided in separate reports relating to service management (34), systems management (36), service planning (38), and managing of change (40) The definitions and formulas used to calculate these cost data and metncs are provided in the detailed descπption which follows. The formulas can be programmed on a computer, such as in a spreadsheet (e g., Excel), to calculate the costs and metncs and display or pnntout reports
The cost categories are to be as precise and detailed as possible so that benchmarks from external data providers can be referenced The costs are preferably evaluated on an annual basis, for the BASE costs as well as the ONGOING costs. Each time when necessary the life-cycle and depreciation of capital expenditures will have to be detailed and the global labor costs for a given time peπod annuahzed.
The costs are categonzed as follows: Base costs include 1) Design; 2) Acquisition Costs; and 3) Installation Costs. Ongoing costs include 1) Direct Costs; 2) Systems management - aligned to MODE'S System's Management
Category; 3) Changes and upgrades - with many references to MODE'S Managing Change Category; 4) Support - with references to MODE'S Service Management Category; 5) Other Operational costs; 6) Indirect costs; 7) End User; and 8) Downtime.
Base Costs - Detail
The base costs are descnbed m detail below The base costs are identified by "Cost Data" designations CD1 through CD 15 , which are depicted in Fig 1 Capital and Expense costs are distinguished, as they are most of the time accounted for separately in the chart of accounts of a company. There are only labor Expenses in the Design and Installation Costs section, whereas the
Acquisition Costs section pertains to the Capital expenditures.

Enterpnse Management software is included in this category, and can offer bundles for the previous systems management features.
"CD 10" costs relate to utility software. CD 10 costs include the capital expenditures for both multimedia software (videoconferencing tools), and end user utilities (screen savers, disk managers, PhotoShop, etc.) which are not productivity enhancing. Other entertainment software (audio and video tools) are included here
Installation Costs In the installation phase, it is expected that there will be no further matenal costs but only labor costs. Though these expenses will be both contracted labor costs and m-house labor costs.
After the installation phase is completed, the system is expected to be operational. The following labor categones have been identified "CD 11" costs relate to hardware set-up CD11 costs include after labor expenses (internal + external) associated with the deployment of the network and system infrastructure: i.e., put the network devices and the workstations m place, pull down the cables and connect all the workstations to each other. There is also costs to setup the router according to the network topology and all the other network connectivity devices, depending on the protocols used.
"CD 12" costs relate to operating system installation. CD 12 costs include the labor costs (internal + external) associated with the installation of any operating system (UNIX, Windows NT/95, etc.). "CD 13" costs relate to application software. CD 13 costs include the labor costs (internal + external) associated with the installation of all the applications related in the previous section.
"CD 14" costs relate to groupware and communication software CD 14 costs include the labor costs (internal + external) associated with the installation and configuration of all the messaging software and the databases.
"CD 15" costs relate to systems management software. CD 15 costs include the labor costs associated (internal + external) with the installation of the network and systems management platform and the anti-virus systems.
Ongoing Costs - Detail
The ongoing costs are divided into two categones: the direct costs (CD 16-
CD39) and indirect costs (CD40-CD44). The direct costs are the budgeted costs to maintain and optimize the availability of key network resources, manage the system and implement the changes, and support the network users. The indirect costs are expenses that are not budgeted and often not accounted for in most of the IT organizations. These hidden costs make the true costs of IS systems underestimated, because the impact of downtime - which is a crucial factor increasing the overall costs - is too often not measured. Direct Costs
As the overall planning phase of the systems management is assumed to be included m the "design" phase, this part of the labor is not taken into account as a whole here. Nevertheless for some areas an ongoing planning phase will be part of a systems management component.
The categoπes tend to match the MODE framework.
"CD 16" costs relate to application management. The annual labor expenses (internal + external) for ongoing management of applications including control and access management, pnnt management and file transfer and control. These costs may include development costs.

"CD27" costs relate to asset management. The annual labor expenses for asset mventoπes (physical or automatic), asset identification and tracking, asset database management, change recording and/or managing automated asset management systems. Asset management is mventoned here because it is necessary to know what exists before implementing a change.
"CD28" costs relate to product evaluation and testing The annual labor expenses for evaluation and testing of new technology mateπals (hardware, software) pnor to purchase. Here are also accounted for the "vendor management" ongoing labor costs (see DESIGN section)

"CD33" costs relate to casual learning. The annual labor expenses of IS professional's time spent on independent, self-education and learning outside of formal training programs. Topics include self-education on computers, networks, printers, storage systems, network communication devices, as well as IS utilities and end-user applications
"CD34" costs relate to training The annual labor expenses and fees for develop, deliver training courses and train as well end users as IS personnel. This includes
The labor time spend on training courses development (design, development, testing and maintaining IS and end-user courseware - inci CBTs)
The labor expenses for dehvenng IS courses as well as the time spent by IS personnel in attending courses (both m-house and external courses)
The labor expenses for the delivery by trainers of end-user training courses, and the time spent by end-users on computer systems and all application training (incl. the initial framing just after rollout) "CD35" costs relate to operating costs. The annual fees for support tools (books, etc.) and travel. The travel expenses include as well the travel time to support remote branch offices, attend training sessions, visit vendors as the travel expenditures.
This category pertains to the costs that are not associated either with maintenance, support, or changes. It is the last category associated with "hard costs," the other indirect costs being more subjective are often referred to as "soft" costs. "CD36" costs are related to communications fees The annual expenses for communication fees such as lease line fees, on-line access-fees, remote access services, WEBTSP hosting fees, and allocated WAN fees.

"CD39" costs relate to insurance. The annual fees for insurance agamst theft, voltage shortage (implying data loss), etc.
The indirect costs are those that are not ongmally budgeted because they stem from a productivity loss due either to the end user themselves or to unplanned systems downtime. The majonty of these metrics are sometimes difficult to measure. These costs are identified as CD40-CD44, as shown in FIG.
1. End User
When end-users are diverted onto IT support onented work, it results in a decrease of the global productivity of the company. For example, the higher the salary of an end-user is, the more important it is that they perform their core role and not spend time on self-learning and peer support. These costs are at best calculated estimates.
"CD40" costs relate to casual learning. The annual labor expenses of end users framing themselves in lieu of formal training programs. Time includes reading manuals, using on-line help, tnal and error, and other self-learning methods. Costs can be higher for casual learning than formal learning an inadequate formal training will result in high casual learning expenses
"CD41" costs relate to peer and self support. The annual labor expenses for end users supporting themselves and each other instead of obtaining technical support from help desk or IS personnel. These tasks-repair, support, maintenance. installation, framing- are performed extensively by end-users in remote offices not staffed by dedicated IS personnel or covered by support contracts.
"CD42" costs relate to Futz factor. The annual labor expenses associated with the development and customization of non-busmess applications (Notes scnpts, etc.), the unnecessary changes to their computer or network settings (screen, file organization, folder, sounds, pnnters, etc ), and the time spent on playing games or web surfing
Downtime expenses are defined as a potential annual loss due to the unavailability of the IT Infrastructure due to faults, and its impact as measured as loss of productivity.
Most organizations lack accurate direct measurements of downtime, and even often do not track system reliability, therefore it is difficult to quantify the losses in terms of business revenues or productivity Nevertheless, downtime causing lost productivity is considered Downtime can be either due to the waiting for a help desk problem to be resolved, to an infrastructure issue (planned maintenance), or unplanned failures (application bugs or inaccessibility, network outages, etc.), for example.
"CD43" costs relate to planned downtime. The annual productivity losses to end users from planned system maintenance, including downtime for backups or migrations of databases and optimizations.
"CD44" costs relate to unplanned downtime. The annual productivity losses to end users from unplanned outages of the network resources, including client computers, shared servers, pnnters, applications, communication resources, and connectivity. The unplanned network outages are almost always obtained from end user surveys.
The appraisal metncs are intended to be key performance indicators for IT operations as a measurement and assessment tool for the TCO, to evaluate and monitor its effectiveness. Different areas, divided mto sections, have been distinguished to facilitate the comprehension and the use of all the metncs along the analysis. The comparison with available market data should allow then to elaborate best practices.
When computing the metrics, the parameters involved are preferably must be homogeneous, i.e., each parameter has to be measured within the same time penod. The time period is taken to be equal to one year. The metrics are categonzed as follows:
Financial Perspective (FP): 1) Cost effectiveness; and 2) Budget management and repartition. Ability to operate effectively and efficiently the IT operations and Systems Infrastructure (OEE). 1) Quality; 2) Availability: and
3) Efficiency. Infrasfrucmre and evolution perspective (IEP): 1) Adaptability, and 2) Future requirements and growth. Metrics Template
In order to have standardized metncs, all the metncs are constructed according to the same template. This template defines the name of the metnc and gives it a number, provides the MODE functions that are involved, indicates the parameters that are involved, how to compute them, the objective of each metnc and additional comments.
Financial perspective (FP)- The FP metncs look at the TCO m terms of its financial performance. To achieve this, ratios are computed for different cost metncs, and then organized by topic
FPI-A TCO budget ratio
• MODE ftmctιon(s) or Category involved: SERVICE MANAGEMENT/ Administration - Billing & Accounting • Data Elements and Unit of Measurement: The TCO budget \ alue
(measure 1). S; the total business budget value (measure 2) S
• Formula: Measure 1 / Measure 2 * 100%
• Metnc objective and additional comments. This metnc can be used to provide benchmarking and estimating guidelines for TCO and IT budgeting. Here the business budget value considered is equal to the total costs of the entire business including operations and project costs. The larger this rate is, the more the company is technology-onented or its network systems are meaningful to it (if there are many applications cπtical to business, the costs associated with the Corporate system will be higher since the network operations will have to be very effective). Salaries
FP1-B Average Corporate Salary
• MODE functιon(s) or Category involved: SERVICE MANAGEMENT/ Administration - Billing & Accounting. • Data Elements and Unit of Measurement: The sum of all employees yearly salanes (measure 1)...S. The total number of employees (measure 2).
• Formula: Measure 1 / Measure 2.
• Metnc objective and additional comments: This metnc measures how costly the staff employed are in the company. It would be very interesting to know the salary structure too. in order to better assess the indirect costs, since the costs associated to downtime and end-users are directly linked to the salary of the end-users concerned.
Support cost ratio
FP1-C: Support Costs per FTE
• MODE functιon(s) or Category involved- SER VICE MANAGEMENT'
Administration - Billing & Accounting, Help Desk and /Qualm Management - Training.
• Data Elements and Unit of Measurement The total cost of support desk - see TCO "Support category," Σ(CD31 +.. -CD35) (measure 1 ) ..S. The total number of hours a user works on average per year (measure 2).
• Formula: Measure 1 / Measure 2.
• Metric objective and additional comments- The point m measuring this cost on a per user basis is to take mto account the potential changes in the organization: in case of great changes, the aggregate support desk cost may be misleading.
Its objective is to provide a benchmarking device and an estimating guideline, but it can also be used to determine the effectiveness of efforts to reduce the costs or improve the efficiency of the support devices. Ideally, increases of the costs m this area should result in cost decreases in other areas, especially in the other support desk metncs.
Budget Management And Repartition
FP2-A ■ Cost Variance from Total Approved Budget
• MODE functιon(s) or Category invoK ed: SERVICE MANAGEMENT/Administration - Billing & Accounting.
• Data Elements & Unit of Measurement. Actual TCO for the previous financial year (measure 1 ) - compute the sum of all costs related Σ(CD1+ . +CD44).. S. Budgeted TCO for the previous financial year
• Formula: Measure 1 - Measure 2 / Measure 2.
• Metnc objective and additional comments: This metnc measures the effectiveness of management of TCO budgets, showing the variance from total approved budget. It is obtained by dividing the acmal TCO minus the budgeted
TCO by the budgeted TCO for the last financial year.
Ideally, the actual cost should not go over the budgeted cost, and should not be more than 5% less than the budgeted cost (otherwise the budget would be badly managed).
Ongoing costs ratios
This metnc is actually an aggregation of several metrics, each being a ratio between different areas of the ongoing costs. The areas considered are support, systems management, change and upgrades, and indirect costs.
FP2-B. Support to Systems Management Ratio
• MODE functιon(s) or Category involved: SERVICE
MANAGEMENT/Administration - Billing & Accounting, Help Desk and /Quality Management - Training, SYSTEMS MANAGEMENT. • Data Elements and Unit of Measurement: Systems Management Costs (measure 1) - sum of all the costs related Σ(CD16+...+CD25)...$. Support Costs (measure 2) - sum of all the costs related Σ(CD31+...+CD35)...$.
• Formula: Measure 2 / Measure 1 * 100%. • Metnc objective and additional comments. This ratio is an indicator for the rate of reactive to proactive budgeting. It also provides a benchmarking device. A trade-off has to be found between support and systems management.
FP2-C: Changes & Upgrades to Systems Management Ratio
• MODE functιon(s) or Category involved: MANAGING CHANGE. SYSTEMS MAN A GEMENT
• Data Elements and Unit of Measurement. Systems Management Costs (measure 1) - sum of all the costs related Σ(CD16+...+CD25)...S. Changes & Upgrades (measure 2) - sum of the costs related Σ(CD26+...^CD30). S
• Formula: Measure 2 / Measure 1 * 100%. • Metnc objective and additional comments. The importance of change and upgrade cost either reflect a bad planning or a firm policy that encourages frequent changes. The higher the rate is, the shorter the system's life span could be.
FP2-D Indirect Costs to Direct Costs Ratio
• MODE functιon(s) or Category involved: SERVICE
MANAGEMENT/Administration - Billing & Accounting. SYSTEMS MAN AGEMENT/F allure control - Fault Management. SERVICE PIANNINGS/Service Management Planning - Training Planning.
• Data Elements and Unit of Measurement. Direct Costs (measure 1) - the sum of all costs related Σ(CD16+...+CD39)...$. Indirect Costs (measure 2) - the sum of all costs related Σ(CD40+ ... +CD44) ... $ .
• Formula: Measure 2 / Measure 1 * 100%. • Metric objective and additional comments. This ratio provides a benchmarking device for the cost estimations. There is a great point in reducing the ratio between the indirect costs and the total of direct costs, as direct costs are more easily measured and thus predictable. As the indirect costs are depending strongly on the performance of the two last related MODE functions, this rate indicates also how well downtime and peer support can be avoided.
FP2-E: Ongoing to Base Cost Ratio
• MODE functιon(s) or Category involved: SER VICE MAN A GEMENT Administration - Billing & Accounting. SYSTEMS PIANNINGS/MODE
• Data Elements and Unit of Measurement. The Ongoing costs (measure 1) the sum of costs related Σ(CD16+...+CD44)...S. The Base Costs (measure 2) - the sum of all costs related Σ(CDl+...+CD 15 )...$. • Formula: Measure 1 / Measure 2.
• Metric objective and additional comments. This ratio allows to give an overview of the manageability and the complexity of an organization and the reliability of the technology and matenals used. Depending on the life cycle of the system-the longer the better- it can be useful to have a small ratio
labor costs Ratios
Again this metric is an aggregation of two metrics that intend to define the importance of the labor costs for the TCO as well as outsourcing trends.
FP2-F: Ratio of External to Internal Labor Costs
• MODE functιon(s) or Category involved: SER VICE MAN A GEMENT/ Administration - Billing & Accounting and Contract Management.
• Data Elements and Unit of Measurement. The Internal labor costs (measure 1) ...$. The External labor costs (measure 2) ...5.
• Formula: Measure 2 / Measure 1. • Metric objective and additional comments As there are many metncs gathenng both internal and external labor costs, it is not possible to reference metncs in order to computer this ratio To compute it, it is assumed that the external labor costs are made up by both service contracts and contractors, and the sum of all these external labor costs are divided by all the internal labor costs
This ratio can be used to compare similar industry companies to determine industry trends in the way that some IT operations are outsourced Sources such as Gartner Group provide information about outsourcmg trends that can be used for benchmarking
FP2-G Ratio of Labor Costs to Other Costs
• MODE functιon(s) of Category invoked SERVICE MANAGEMENT Administration - Billing & Accounting and SERVICE PLANNIN 7./ODE
St ategic Planning
• Data Elements & Unit of Measurement 1 ) The Internal labor costs (measure 1) $, 2) The External labor costs (measure 2) $, and 3) The TCO for the last fiscal year (measure 3) S
• Formula (Measure 1 + Measure 2) / (Measure 3 - Measure 1 - Measure 2)
• Metric Objective & Additional Comments This ratio allows to detect if a technology improvement is needed, e g in the systems management field where momtonng and asset management can be automated The results of the previous metnc allows to determine the overall labor costs For each cost element used to calculate the total TCO, the labor costs are indicated
Ability to operate effectively and efficiently the IT operations and Systems Infrastructure (OEE)
The metncs in this area measure the performance of the business, focusing on system and operations quality, availability, and efficiency Quality
OEEI-A: Number of Faults per User
• MODE functιon(s) or Category involved: SER VICE MAN A GEMENT/ Quality - Quality. SYSTEMS MAN AGEMENT/Failure control - Fault
• Data Elements and Unit of Measurement. The total number of incidents presented Tier 2 service Desk (measure 1) The total number of users (measure 2). • Formula: Measure 1 / Measure 2.
• Metric objective and additional comments This metric measures the reliability of the technology implemented withm the system It is obtained by dividing the total number of incidents presented to Tier 2 service Desk by the total number of users of the whole systems during the past year. The higher this rate is, the less reliable is the technology used, and this could dramatically increase the costs associated with troubleshooting and repair
System 's performance rating
Those two aggregated metrics measure the system global performance and security.
OEE1-B System 's Performance Demand
• MODE functιon(s) or Category involved' SERVICE MANAGEMENT/Productwn control - Production Scheduling.
• Data Elements and Unit of Measurement: System's performance demand rating Rate from 1 to 5. • Formula: No formula needed.
• Metric objective and additional comments This metric e\ aluates the global systems performance required by company business needs. The systems overall performance will be rated from 1 to 5, according to both technology efficiency (bandwidth available, file transfer speed, storage capacity) and fault tolerance and recovery (e.g., banks are very sensitive to downtime); basic technology and great fault tolerance; medium technology and great fault tolerance; medium technology and little fault tolerance; high technology and little fault tolerance; high technology and no fault tolerance.
OEE1-C: Physical and Logical Security Rating
• MODE functιon(s) or Category involved: SYSTEMS MANAGEMENT/Monitoring - Physical Site Management and / Security Management
• Data Elements and Unit of Measurement: Physical and logical security rating... Rate from 1 to 5.
• Formula: No formula needed.
• Metric objective and additional comments. This metric evaluates the performance of the system in terms of security. The rating, going from 1 to 5, allows to indicate how important security is to the company, and then to assess the budget that could be spent on this area. For a given rate and according to the industry sector, benchmarks concerning budgets allocated to security may be available; system not secured; system poorly secured; system globally secured; system well secured; and system highly secured.
OEE-2A: Downtime Rate
• MODE functιon(s) or Category involved: SER VICE MAN A GEMENT/Quality Management and SYSTEMS MAN A GEMENT /Failure control. • Data Elements and Unit of Measurement: The total network downtime (measure 1)....Hours; and The total number of hours a user works on average per year (measure 2)...Hours.
• Formula: Measure 1 /Measure 2 • Metnc objective and additional comments. This metnc measures unavailability of the network, either due to planned interruptions, or to technology failures during the past year. Included in downtime is time a user waits for a problem to be resolved. The productivity loss should be taken into account as an indirect cost when setting the TCO budget, and it is important to notice that the support team's efficiency can dramatically decrease downtime
This metric measures both the call reloggmg rate and abandonment rate at the Help Desk.
OEE2-B Call Relogging Rate
• MODE functιon(s) or Category involved: SERVICE MANAGEMENT/
Quality Management and Help Desk
• Data Elements & Unit of Measurement. The number of calls that have been relogged by the Help Desk (measure 1) The total number of calls presented to the Help Desk (measure 2) • Formula: Measure 1 /Measure 2
• Metric objective and additional comments. This measurement, obtained by dividing the total number of relogged calls by the total number of calls presented to the Help Desk dunng the past year, check the availability of Help Desk people. A high percentage value for this metnc indicates a poor success rate at resolving the underlying causes of problems.
OEE2-C Call Abandonment Rate
• MODE functιon(s) or Category involved • SER VICE MAN A GEMENT/ Quality Management and Help Desk • Data Elements and Unit of Measurement- The total number of calls abandoned pnor to closure (measure 1). The total number of calls presented to the Help Desk (measure 2).
• Formula: Measure 1 /Measure 2. • Metnc objective and additional comments This rate assesses the capability of the Help Desk to handle the received calls. In case of a high rate here, the end user downtime or peer/self support could increase, which results in a productivity loss. The higher the result for this metnc the lower the ability of IT Operations to provide a fault resolution service; on the other hand a low value for this metric indicates a sufficient call taking capacity for the Service Desk
Average response and resolution time
These two metncs correspond to two consecutive steps in the resolution of a problem: first reporting, and then solving.
OEE3-A Average Response Time
• MODE functιon(s) or Category involved- SER VICE MAN A GEMENT/ Quality Management and Failure Control
• Data Elements and Unit of Measurement The time it has taken to the support organization to respond to all incidents or problems (measure 1 ) - see m the Monitoring section of Systems Management ..Hours The Number of incident problems tallied (measure 2).
• Formula. Measure 1 /Measure 2
• Metnc objective and additional comments- The average response time metnc determines the average time it takes the support organization to respond to an incident or problem. Normally, response time is defined as the time from the support organization first being aware of the incident or problem to the time at which the first action is taken (usually informing or giving status to users) It may be divided into further metncs based on the cnticality of the requests (low, medium, high, cπtical).
OEE3-B Average Resolution Time
• MODE functions) or Category involved: SER VICE MAN A GEMENT/ Quality Management and Failure Control.
• Data Elements and Unit of Measurement. The time it has taken to the support organization to resolve problems as soon as requests were reported (measure 1) - see LAN/WAN troubleshooting & repair...Hours Number of Incident/problems tallied (measure 2) Hours. • Formula- Measure 1 /Measure 2.
• Metnc objective and additional comments The average resolution time is the measure of the time from an incident or request being reported to the time at which it is resolved One can distinguish the "incident" and "request" categones: an incident is an occurrence-system error or malfunction-that requires assistance from the support organization, whereas a request refers to an action that a user asks to be performed that is usually related to network/workstation administration or software/hardware changes. Again further subdivision of the metnc can be considered according to the defined cnticality of the incident or request.
It is interesting to compare these metrics in order to assess the support organization's efficiency, and define the SLAs
Help Desk Call Handling rate & staffing ratio
These two correlated metncs measure the efficiency of the Help Desk staff.
OEE3-C Help Desk Call Handling Rate
• MODE functιon(s) or Category involved SERVICE MANAGEMENT/
Quality Management and Help Desk
• Data Elements and Unit of Measurement -The number of calls presented to the Help Desk (measure 1).. one; -The total number of Help Desk Tier I staff (measure 2)...None -The average number of days worked by Help Desk Tier I staff (measure 3)... None. • Formula: Measure 1 /Measure 2/Measure 3
• Metric objective and additional comments. By dividing the total number of calls received by the Help Desk first line support staff by the average total number of Tier I support staff and by the average number of days worked during the past year, one can determine the productivity rate of the Tier I Help Desk staff.
OEE3-D: Help Desk Staffing Ratio
• MODE functιon(s) or Category involved: SERVICE MANAGEMENT/Help Desk.
• Data Elements and Unit of Measurement: The total number of Help Desk Tier I staff (measure 1 ) ... The total number of users (measure 2 ) .
• Formula: Measure 2/Measure 1
_ • Metric objective and additional comments. By dividing the total number of end users by the number of Help Desk personnel one have a good indication of the effectiveness of the Help Desk. The two metncs (OEE3-C and OEE3-D) are conelated. because if the percentage associated to one metric increases, the other percentage associated to the second metnc should also increase. Nevertheless, by multiplying those two rates, the number of calls that are presented to the Help Desk per employee is obtained, which is another interesting metric. Desktop services delivery
OEE3-E- Average Time to Deliver a PC to Desk
• MODE functιon(s) or Category involved: MANAGING CHANGE/ 'Implementing - Procurement. • Data Elements and Unit of Measurement: The aggregate time to deliver all PCs accepted dunng the previous year (measure 1). Days. The number of PCs ordered dunng the last year (measure 2).
• Formula: Measure 1 /Measure 2.
• Metric objective and additional comments This metric measures the average time to deliver desktop services, from the order to the end of the installation, including the delivery and configuration. It allows to determine the flexibility of the system and its ability to administrate the users
This metnc measures both the rate of ongoing systems operations covered by SLAs as the actual performance of these operations agamst the SLAs
OEE3-F SLA 's Operations Coverage Ratio
• MODE functιon(s) or Category involved: SER VICE MANAGEMENT/SLA Management
• Data Elements and Unit of Measurement: The number of Operations that are covered by SLAs (measure 1) The total number of Operations (measure
• Formula Measure 1 /Measure 2 * 100%
• Metric objective and additional comments- This metnc shows how the operations are covered by SLAs. According to best practices, the SLAs should cover 100% of Operations to ensure that services rendered are according to requirements and any discrepancies can be easily identified and rectified as needed. OEE3-G Operations Performance against SLA 's
• MODE functιon(s) or Category involved: SERVICE MANAGEMENT/SLA Management - Reporting and Quality Management - Quality Management • Data Elements and Unit of Measurement: The total number of
Operations Performance Measures that are covered by SLAs (measure 1). The number of Operations Performance Measures that fail to meet SLAs requirements (measure 2)
• Formula: Measure 2/Measure 1 * 100% • Metric objective and additional comments The result allows to show the performance of the system compared to the established targets. The SLAs can thus be corrected if necessary, and/or the systems performance improved Infrastructure and evolution perspective (IEP)
This area looks at the scalability of the infrastructure and at how sustainable the performances are likely to be m the future.
System 's scalability
This measure rates the upgradeabihty of the system's technology from 1 to 5. depending on the different technologic features of the system, gives the number of different platforms operated and the system's like span to assess the system's flexibility.
IEP I- A Svstem 's Upgradability and Life Span
• MODE functιon(s) or Category involved: MANAGING CHANGE/Controlling - Asset Management and SERVICE PLANNING/MODE Strategic Planning.
• Data Elements and Unit of Measurement. The number of platforms operated. The systems life span.
• Formula: No formula is required The metric is a rating from 1 to 5 that results from the values of the measures above • Metnc objective and additional comments This rating allows to evaluate the system's complexity, scalability, and durability (1 = not scalable, short life span, 2 =httle scalable, short to medium life span, 3 = scalable but complex, medium life span; 4 = scalable and not very complex, medium to long life span, and 5 = very scalable, long life span)
WAN bandwidth utilization
This metnc measures the percentage of bandwidth used
IEP1-B WAN Bandwidth Utilization
• MODE functιon(s) or Category involved SYSTEMS MAN A GEMENT /Monitoring - Performance Management
• Data Elements and Unit of Measurement The bandwidth that is used (measure 1) Mb The total available bandwidth (measure 2) Mb
• Formula Measure 1 /Measure 2 * 100%
• Metnc objective and additional comments Bandwidth utilization is to be measured at a peak time with utilization duration greater than five minutes
In addition, the percentage of time that use falls between a specified range is also measured, the objective could be to determine if the WAN bandwidth utilization is withm a certain range and if it is not. the extent and frequency with which it is out of range This also allows to see the supportable traffic increase on the network
NB Information about bandwidth utilization is usually given as part of standard reports from WAN providers
IEPXC Average Training Hours Delivered per FTE
• MODE functιon(s) or Category involved SER VICE MANAGEMENT /Quality Management - Training • Data Elements and Unit of Measurement The aggregate number of training hours delivered last year (measure 1)...Hours; The total number of hours a user works on average per year (measure 2) ..None
• Formula: Measure 1 /Measure 2 • Metnc objective and additional comments This metnc measures the capability of the human resources to tram people As a result, a more highly trained staff is likely to be more flexible as everyone is then more likely to fulfill a vanety of roles.
Change IEP1-D Average Time to Implement a Change
• MODE functιon(s) or Category involved MANAGING CHANGE
• Data Elements and Unit of Measurement The aggregate time that it took to the company to implement registered changes (measure 1) and The number of changes that have been implemented (measure 2) None • Formula: Measure 1 /Measure 2
• Metnc objective and additional comments This measure indicates how long it takes in average to the company to carry change related projects It provides a good benchmark for the potential changes that were foreseen
Future Requirements and Growth Planning
This metnc measures the length of planning horizon m cuπent long term operational plan. It is cmcial to have access to this data in order to assess the effectiveness of the organization
IEP2-A Length of Planning Horizon
• MODE functιon(s) or Category involved SERVICE
PLANNING/MODE Strategic Planning
• Data Elements and Unit of Measurement Length of planning honzon in current long term operation plan Years • Formula: None
• Metnc objective and additional comments. In general the longer the length of IT Operations planning honzon the more effective that organization is going to be at predicting future demand. However, some caution should be applied as any detailed planning is unlikely to be feasible beyond a year planning honzon and even more generalized planning is likely to become less useful beyond 3 years. An IT Operations function that has horizon of 3 years or more, can be considered 'capable' in terms of this metric. Growth perspective This metnc is an aggregation of three separate metncs that tend to indicate the organization's orientations.
IEP2-B: End-user Staff Growth or Attrition
• MODE functιon(s) or Category involved: SER VICE PLANNING MODE Strategic Planning • Data Elements and Unit of Measurement: The number of new joiners expected (measure 1). The number of persons that are expected to leave the company (measure 2). The total current number of employees (measure 3).
• Formula: (Measure 1 + Measure 2)/Measure 3
• Metnc objective and additional comments. The end-user staff growth or attrition rate has consequences on all the metrics that deal with labor costs, so it is interesting to predict the changes in order to assess the overall new budget.
IEP2-C: Budget Estimation
• MODE functιon(s) or Category involved: SERVICE PLANNING/Service Management Planning - Service Pricing and Costing • Data Elements and Unit of Measurement: The expected TCO budget for next year (measure 1) The current TCO budget (measure 2).
• Formula: (Measure 1 - Measure 2)/Measure 1 • Metnc objective and additional comments. The vanance of the next budget compared to the current budget is related to an overall planning of operations, changes, and technology orientations. As a result, many metncs will be affected by the budget onentations that are reflected in this metnc.
IEP2-D' Performance Expectations
• MODE functιon(s) or Category involved: SER VICE PLANNING/Managing Change Planning
• Data Elements and Unit of Measurement: The performance improvement expectation (measure 1) ... Rate from 1 to 5 • Formula: Measure 1
• Metric objective and additional comments This metric indicates how the performances of the system should improve: no improvement needed: little improvement needed; medium improvements needed: great improvements needed; overall cntical improvements required.
Appraisal Metrics Interrelationships
The relationships that exist between the different appraisal metncs defined m the previous section are descnbed in more detail below. The information can be used as a starting point in the interpretation of both cost data and appraisal metncs before beginning the benchmark study. Interrelationships Overview
The relationships between the metrics can be summarized in a symmetnc matrix featunng different types of relations:
- One metric can influence another metric, i.e., its value has direct consequences on the another metnc 's value. Example: The average Corporate salary of a Company influences the
Support Costs per FTE, since the Support Costs are labor costs that are at least partly performed by employees of the company
- One metric can be similarly influenced by another metnc, i.e.. its value is partly determined by another metric' s value. - Two metncs can have a complementary relationship, i.e., their vanations should be correlated.
Example: If the FTE downtime rate increases, the Cost vanance from total approved budget should also increase since FTE downtime begets Indirect costs that are not predicable. In this case, we have a kind of "indirect influence" between the first and the second metnc.
- Two metncs can have a trade-off relationship, i.e., if the value of one metnc increases, the value of the other should tend to decrease.
Example: There is a trade-off between the Help Desk staffing ratio and the Call relogg g rate. If the Help Desk support staff increases, more calls could be handled and thus the Call reloggmg rate would decrease.
For each metnc, the related metncs as well as the nature of their relationships is provided in the Tables below. All the metncs except those related to Infrastructure and Evolution Perspective, i.e., metncs IEP2-B, C and D, have relationships with other metncs, and often there are cross-categories relationships.
One has to be careful when considenng the metrics associated with time, because a "complementary relationship" can either tend to increase or decrease its value For those types of metncs, the influence of other metrics on the time and the inverse of the time that indicates the performance for this type of metric ments close analysis.
