How to Create a Schedule from a Precedence Diagram
The following diagram indicates that there are numerous inputs to the project schedule in addition to the precedence diagram.
Other areas you need to consider include:
As the project manager, you first determine what must be done to complete each task; this means identifying the necessary roles and the needed skills. Then you determine who has the required skills and assign them to the appropriate roles. The people assigned must have the skills necessary to fulfill these roles. If they do not, you might need to add more people or change the schedule to allow time for training.
The challenge is to coordinate all of these inputs to develop a schedule that satisfies all the stakeholders.
