One of the lesser utilized yet powerful ideas in ITIL is the concept of systems or feedback loops. ITIL defines a system as A group of interacting, interrelated or interdependent components that form a unified whole, operating together for a common purpose. There are two types of systems: · Open-loop systems – value of outcome has no influence on input; performs a specific activity regardless of environmental conditions · Closed-loop systems – value of outcome influences input; responds to changes in the environment Using these concepts we can establish a powerful approach for managing and improving the ITIL processes we have implemented. One technique is called the Monitor-Control Loop. The loop consists of a set of steps that produces feedback to help improve individual process steps, the process as a whole, the stages of the lifecycle and the lifecycle as a whole. · Begin the loop by conducting an individual process step by taking inputs and
