Project Management-Chapter 7 Ideas

In this Chapter, I learned tasks that can be performed at the same time are known as concurrent tasks. There are two basic rules when graphing task relationships with a network diagram. 1. define task relationships only between work package. Even though a project might have hundreds of work package and several levels of summary tasks, keep the sequence constrsints at the work package level. Summary tasks are simmply groups of work packages, so it wouldn't make sense to put a task relationship between a summary task and its work package. 2. Task relationships should reflect only sequence constraints between work packages, not resource constraints. Changing a network diagram becuase of resource constraints is the most common error in building network diagrams. The fact that there aren't enought people or other resources to work on multiple tasks at the same time is irrelevant. Regardless of resources, the tasks will still have to be performed in the same order.
I also learned five steps of planning: planning, identify task relationships, estimate work packages, calculate an initial schedule, and assign and level resources.
