Recall that the critical path method is a management scheduling tool that identifies the activities needed to complete a task or project, specifies the time each activity will take, and shows the relationships among the network of activities to determine the total completion time of the task or project. Let's examine the critical path method as it applies to a maintenance project. Suppose that you are a maintenance supervisor and your department has to overhaul a piece of equipment. You have determined that the following activities must be completed in the following order and each will take a specific number of days to complete (see table below). A B D F G ACTIVITY IMMEDIATE PREDECESSOR (ORDER OF ACTIVITIES) None A MAINTENANCE PROJECT A B, C D D F, E TIME TO COMPLETE ACTIVITY IN DAYS 7 2 4 5 2 4 5 Estimate how long it will take you to finish this maintenance project. Remember, the estimated completion time is obtained by adding the hours necessary to complete the series of activities that comprise the longest route, in terms of time, to complete the job
