  16. Figure 15-15, Snapshot of a project issue base. Issues i1 and i5 have been resolved, whereas all other issues are still open. Dependencies among issues indicate that the resolution of an issue can constraint the alternatives for dependent issues. i1:Issue status={Closed} i5:Issue status = {Open} i2:Issue status = {Open} i7:Issue status={Closed} i3:Issue status = {Open} i6:Issue status = {Open}

  17. Figure 15-16, The waterfall model as a special case of the issue-based life cycle model. All issues that belong to the same issue category are contained in the same UML package. In the project status shown in the figure, all the requirements elicitation and analysis issues have been closed; that is, the requirements elicitation and analysis activities have been completed. Req. Elicitation Analysis i1:Issue i5:Issue status={Closed} status={Closed} i2:Issue i7:Issue status={Closed} status={Closed} i3:Issue System Design status={Closed} i6:Issue status = {Open}

  18. Figure 15-17, In a complex project state, all activities can still have some open issues, which means that all activities need to be managed concurrently. Req.
