Introduction

CPM is commonly used with all forms of projects, including construction, aerospace and defense,
software development, research projects, product development, engineering, and plant
maintenance, among others. An activity network Diagram is also called: arrow diagram, network
diagram, activity chart, node diagram, CPM (Critical Path Method) chart or PERT (Program
Evaluation and Review Technique) chart.

10.1 Critical Path Computation

In the Activity Diagram described in the before, a network of tasks were set up to show the
dependent sequence of activities within a project. The Critical Path Method can be applied to
such as network to answer the most ordinary question asked of project managers: How long
will the overall project take?
Some ‘project management’ computer programs, such as Microsoft Project, will compute the
critical path for you. You can also do it by hand or build a spreadsheet to calculate it, using the
method described below.
