Practical Service Level Management: Delivering High-Quality Web-Based Services

Advantages of Simulation Modeling

Our ability to what-if is limited by the constraints of time and information. It takes time to understand a complex environment and all its subtle interactions. There is the time expended in staying current with the constant changes in a dynamic services ecosystem. It takes additional time to work through a what-if scenario. The iterative nature of a what-if exploration really compounds the time constraint. The usual process is seeing a change that indicates an improvement, problem cause, or a sensitivity factor and then pursuing it further.

The next questions that naturally arise are as follows:

• Is this change really causing the improvement?

• Where are we in the variable's range? Will a bigger change to it lead ...
