ABC Video Rental software package options:

Using the table above as a guide, develop a critical path method (CPM) for the design phase of ABC's project. While you do the diagram, reason through the dependencies. Assuming Sam (software engineer) and Mary (project manager) do the project alone, how should the work be allocated among them to (a) allow Mary to do project management tasks, and (b) leverage the work they did during analysis?

Use 3-point estimation or CoCoMo methods for your task estimations, and be sure to mention all the dependencies, as well as establish an appropriate activity sequence.
