scheduling and expediating,”projects rarely follow the plan (lard) out. During the project the project manager should access each step. If there are delays they should identify alternate actions to bring the project back within the time constraits often this is done by putting more resouces, time or money into a particular activity. THis course of action should be thought carefully. Time and costs need to be traded off to get the project completed. After the critical path and the slack time in other activities have been identified
