Read "Chapter 3: Project Management" (pages 57–82).
As discussed, the software engineer and the project manager provide complementary skills and work collaboratively on shared activities. The three main activities of the project manager are organizational liaison, personnel management, and project monitoring and control. The "Liaison" section (pages 67–70) discusses the project manager's role as a go-between for the technical team and agents who are not members of the technical team (such as project sponsors, users, IS management, vendors, and so on).
In the "Personnel Management" section (pages 70–74), you will learn that this job entails working with personnel and human resources to hire, fire, and provide employees with professional development.
The "Monitor and Control" section (pages 74–79) explains that project monitoring involves tracking project progress relative to budget. Project control means implementing changes when progress is not satisfactory (such as training or revising project plans).
