Consider the software development activities which we described in Section 1.4. Draw an activity diagram depicting these activities, assuming they are executed strictly sequentially. Draw a second activity diagram depicting the same activities occurring incrementally (i.e., one part of the system is analyzed, designed, implemented, and tested completely before the next part of the system is developed). Draw a third activity diagram depicting the same activities occurring concurrently.
What will be an ideal response?
This exercise tests the student’s knowledge of the activity diagram syntax, not the knowledge of software engineering
activities. In the sample solution provided in Figure 2-13, we assumed that requirements elicitation need to be
completed before any subsystem decomposition can be done. This leads to a splitting of the flow of control in the
third diagram where all remaining activities occur concurrently. The instructor could accept a solution where
requirements elicitation also occurs incrementally or concurrently with the other development activities.
