management" best practice as an illustration. Let's assume that change management comprises activities around deployment; retirements and moves; and change management technology and processes. Recognizing the positive TCO impact of best practices for change management, a change management "best-practice scalar" will adjust the original TCO number up or down according to the best-practice index score obtained. Best practice change management can reduce TCO more than 6 percent compared with organizations in which best practice change management isn't in place. 5.3 Worker Type Profile Module This module enables users to simulate their own environments as closely as possible by including a definition of different worker types. Different work roles imply different usage patterns and associated costs. Gartner has defined four types of business workers: Data entry worker: This individual is primarily responsible for transcribing information from one medium to another. The job is computer-intensive and downtime-sensitive, but will also likely have the lowest costs. Typically, this user interacts with corporate database applications. Structured task worker: This individual primarily works within a business process. The work includes repetitive tasks that add some value to a process chain. This worker uses enterprise business applications, such as claims processing. Knowledge worker: This individual works in ad hoc or project mode. The work entails gathering information and adding value to it in support of a business decision. This worker primarily uses personal productivity technology tools. High-performance worker: This individual works in a computer-intensive project mode. The environment is typically graphics- or media-intensive technology. Typically, these are specialized applications (such as design or analytics) running on high-performance workstations, and these users are the most expensive to support. 5.4 Zeroing Indirect Costs If the TCO impact of certain indirect costs is regarded as negligible or tangential to the main focus of the cost management exercise, then the indirect cost elements in the chart of accounts may optionally contain zero costs. Each line item should remain as an indication that it's been acknowledged but deliberately excluded; otherwise, it isn't a Gartner TCO model. Although this removes the "holistic view" of the analysis, it may be more appropriate in some situations. For example, if a TCO for a data center were to be created, there may not be much point in including end-user costs because users wouldn't normally have direct contact with the data center. Any user issues would be handled by a help desk or support function, and would never be directly associated with the data center. However, managers should realize that if they eliminated all end- user support and help desks, then direct costs would naturally decline, while indirect costs would skyrocket as users spent time and money assisting one other. Sometimes, lower costs aren't a
