Effective resource leveling starts with seeing resource conflicts, but doesn’t stop there. As an example, there may be two full-time activities that overlap that are scheduled to be completed by one person, during the same week. In order to resolve this conflict, the project team needs to first be aware of the conflict, then decide what to do about it. For example, they can choose to:
Add an additional person (Cost impact);
Schedule the tasks consecutively (Time impact); or,
Drop the task altogether (Scope impact).
