Main Program

Schedules are still a major source of conflict in the main program phase of the project life cycle, though the proximate cause of schedule-related conflict is usually different than in the earlier stages. Project plans have been developed and approved by everyone involved (although, perhaps, grudgingly), and the actual work is under way. Let us make an assumption that is certain to be correct; let us assume that some activity runs into difficulty and is late in being completed. Every task that is dependent on this late activity will also be delayed. Some of these subsequent activities will, if sufficiently late and if the late work is not made up, delay the entire project.

In order to prevent this consequence, the PM must try to get the schedule back on track. But catching up is considerably more difficult than falling behind. Catching up requires extra resources that the functional groups who are doing the "catching up" will demand, but which the PM may not have.

The more complex the project, the more difficult it is to trace and estimate the impact of all the delays, and the more resources that must be consumed to get things back on schedule. Throughout this book we have referred to the PM's job of managing time/cost/performance trade-offs. Maintaining the project schedule is precisely an exercise in managing trade-offs, but adding to the project's cost or scaling down the project's technical capabilities in order to save time are trade-offs the PM will not take if there is any viable alternative. The PM's ability to make trade-offs is often constrained by contract, company policy, and ethical considerations. In reality, trade-off decisions are extremely difficult.

Like schedule conflicts, technical conflicts are frequent and serious during the main program stage. Also like schedule conflicts, the source of technical conflict is somewhat different than in earlier stages, lust as a computer and a printer must be correctly linked together in order to perform properly, so must the many parts of a project. These linkages are known as interfaces. The number of interfaces increases rapidly as the project gets larger, which is to say that the system gets more complex. The need to manage these interfaces and to correct incompatibilities is the key to the technical conflicts in the main program phase.
