Caltron Inc. produces computer-controlled components for a wide variety of military hardware. As a defense contractor, the company is often under severe time and scheduling constraints. The development of a new component, Vector-12, is no exception. The project has the potential for generating future contracts that could bring in substantial revenue if development and testing can be accomplished in the allotted time.
The planning of the Vector-12 project has been assigned to Norm Robertson. This is Robertson's first assignment as a project director for Caltron, and he is eager to demonstrate his abilities.
This project, like many of Caltron's projects, cuts across departments. Therefore, scheduling and coordinating among departments are crucial. Caltron's management has long been an advocate of the Project Evaluation and Review Technique (PERT). Therefore, Robertson prepared the PERT diagram for the Vector-12 project that follows.

Required:
(1) Discuss the advantages and disadvantages of network analysis as a means of organizing and coordinating projects.
(2) Identify the specific reason that causes Norm Robertson to be concerned about the delay in activity A-D.
(3) Critique the way Norm Robertson developed the PERT diagram for the Vector-12 project.
(4) Discuss the behavioral problems that can arise within Caltron Inc. as a consequence of the planning of the Vector-12 project.
