1. Briefly discuss the S- and J- type project life cycles with examples, and contrast them

2. Consider the use of a "proportional baseline rule" to evaluate project progress - that is, the baseline plan expects the overall completion % of a project to be proportional to the % time elapsed. For instance, with 20% of the time elapsed, expected progress is 20%, with 50% of the time elapsed, expected progress is 50%, and so on. Now, consider two projects: one truly following the S-type another truly following the J-type cycle. What is the likely qualitative evaluation (as ahead, behind, or as expected) of each project type's progress under this "proportional rule" at the i) beginning phase (time elapsed: around 20% of project duration) and ii) middle phase (time elapsed: around 50 %)
