Question
Chapter 7, Problem 4AME
Summary Introduction
Interpretation:The effect of increasing activity A by 1 week after becoming critical is to be determined.
Concept Introduction: Critical path is a method used to evaluate the project. It is used when the activity times are deterministic. It is the longest path in the network. It defines the minimum time required for completion of the project.
