3.  Why are decisions more common in prescriptive process models than in descriptive process models?

Decisions are more common in prescriptive process models because a prescriptive process model is trying to cover what is done in alternative situations. Thus, it may need to specify the decision that is used to decide what to do next. A descriptive process model describes what happened, and alternative actions are usually not included.

4.  Why should tasks in a process model be separated by an artifact?

If one process follows another process, some information or document from the first process is needed by the second. If this were not true, then the two processes would be independent of each other and one would not follow the other. This information or document should be identified and  documented.
