The Usage Model provides a guide in determining which phases, activities and tasks from the overall framwork are used for typical project engagements. Whereas there are differences between the projects, there are also many similarities in the overall approach, tasks and more detailed supporting assets that are required. Therefore, all projects are described in the context of the Overall Implementation Guide and the Usage Model is used to map the relevant tasks required for implementation. The corresponding Solution Offering explains the context in which these activities are used, by describing the use of key activities as part of the solution.
Even if the project is only to do a subset of work, an effort should be made to cross-check the approach against the overall steps in the framework to ensure that all prerequisite activities have been completed. This means that even tactical projects may start with a review of the Blueprint stage.
The FISDev Usage Model is currently under development. An example of a completed usage model can be seen here within MIKE2.0
Applying FISDev into other frameworks provides the approach for using the framework in the context of an overall implementation program with other complementary workstreams.
