Once you have identified and organized your users, applications, and devices into logical groupings, the next step is to clearly define your use cases. This is an iterative process. Some groups might be too broad and should be split into multiple different use cases; other groups might be too tightly focused and can be combined with other use cases. You might also find that two different groups of users have a high rate of commonality and can be merged into a single case, as demonstrated in the following figure:

Creation of a use case

The idea is to minimize the number of unique use cases. There should be as many use cases as necessary, but as few as possible. The more unique use cases that are defined, the more iterations of testing will be required. This will carry forward to image design, which we will cover in detail in Chapter 6, Designing Your Virtual Image Delivery.

In Chapter 1, Planning Desktop Virtualization, we presented several different scenarios to determine...
