Processes

Processes are examples of closed-loop systems because they provide change and transformation towards a goal and utilize feedback for self-reinforcing and self-corrective action (see Figure 2.2). It is important to consider the entire process or how one process fits into another.

Process definitions describe actions, dependencies and sequence. Processes have the following characteristics:

• Measurable: We are able to measure the process in a relevant manner. It is performance driven. Managers want to measure cost, quality and other variables, while practitioners are concerned with duration and productivity.
• Specific results: The reason a process exists is to deliver a specific result. This result must be individually identifiable and countable. While we can count changes, it is impossible to count how many Service Desks were completed.
• Customers: Every process delivers its primary results to a customer or stakeholder. They may be internal or external to the organization but the process must meet their expectations.
• Responds to a specificevent: While a process may be ongoing or iterative, it should be traceable to a specific trigger.

Functions are often mistaken for processes. For example, there are misconceptions about Capacity Management being a Service Management process. First, Capacity Management is an organizational capability with specialized processes and work methods. Whether it is a function or a process depends entirely on organization design. It is a mistake to assume that Capacity Management can only be a process. It is possible to measure and control capacity and to determine whether it is adequate for a given purpose. Assuming that it is always a process, with discrete countable outcomes, can be an error.
