PERT and CPM Scheduling
PERT and CPM Scheduling

These two methods of schedule analysis have been around since the 1950s, and form the foundation of what the profession knows about scheduling today. CPM (critical path method) was developed by DuPont in 195859, and uses fixed-time estimates for each activity. PERT

The Uncertainty of Scheduling the Future
The Uncertainty of Scheduling the Future

Recognize the uncertainty principle at work (see Considering Dependencies). The planned schedule is just the team's best guess of the future. It does have some allowance for uncertainty management with time reserves built into it, just as management builds cost reserves

Why Schedule
Why Schedule

What a question! Why even mess with all the details of trying to figure out what real dates a project scheduling algorithm tells us the project can be finished by, when the date will be declared unacceptable and pulled up anyway? This is a real problem facing many software

Scheduling the Work
Scheduling the Work

The schedule is derived from the WBS and contains activity duration, important milestones and work products to be produced, and who is responsible for them. Generally represented as a Gantt chart, but equally useful as a table, the schedule adds flesh to the WBS backbone,

Brainstorming Dependencies and Activities
Brainstorming Dependencies and Activities

In Identifying the Tasks and Activities we considered identification of the activities and tasks that might be required in a software development project. Particularly, we saw how the 65 activities from 17 software engineering processes explained in IEEE 1074 could be

What Are Dependencies
What Are Dependencies

Dependencies are one form of constraint for any project. Remember the triple constraint shown in What Is a Project Figure ? It says that scope, schedule, and cost are the triple constraints of any project, with quality measurement permeating all three parts. Hard deadlines and

Considering Dependencies
Considering Dependencies

Most activities are not performed in isolation on a project. Identifying proper dependencies is a key part of getting the schedule right. This section discusses some considerations for dependencies common in software development projects, with references to the life cycle models

Organizational Structures

Now that we have a basic understanding of organizations in general, we can look at the common forms that a software development project manager may encounter. In the 1960s and 1970s, various forms of organization were being discussed in the literature. These are shown in
