I will skip the title sheet, which is merely descriptive, and start to work with the function definitions. In this case I highly recommend starting with a few key functions that are likely to provide the majority of the key performance behaviour. If this model turns out to be insufficient at a later stage then add more information as the model develops. This means that the level of detail being worked on remains manageable.

I have received feedback that the performance model would be more useful if it was better documented. The is a tour of the model available (here), but that doesn’t make it clear how to apply the model ina typical usage scenario. I have, therefore, decided to illustrate the use of the model using a fictional example. Continue reading ‘Performance Model Example’ »

During a recent engagement I needed to use queuing theory based modelling to examine the performance of a system. Searching the Internet I found the JMT open source tools:
