GLOSSARY Program evaluation and review technique (PERT) A network-based project schedul- ing procedure. U LG 1 14 Ti €3 Critical path method (CPM) A network-based project scheduling procedure. Activities Specific jobs or tasks that are components of a project. Activities are repre- sented by nodes in a project network. Immediate predecessors The activities that must be completed immediately prior to the start of a given activity. Project network A graphical representation of a project that depicts the activities and shows the predecessor relationships among the activities. Critical path The longest path in a project network. Path A sequence of connected nodes that leads from the Start node to the Finish node. Critical activities The activities on the critical path. Earliest start time The earliest time an activity may begin. Latest start time The latest time an activity may begin without increasing the project completion time. Earliest finish time The earliest time an activity may be completed. Forward pass Part of the PERTICPM procedure that involves moving forward through the project network to determine the earliest start and earliest finish times for each activity. Backward pass Part of the PERTICPM procedure that involves moving backward through the network to determine the latest start and latest finish times for each activity. Latest finish time The latest time an activity may be completed without increasing the project completion time. Slack The length of time an activity can be delayed without affecting the project com- pletion time. Optimistic time The minimum activity time if everything progresses ideally. -I Most probable time The most probable activity time under normal conditions. 9%~ Pessimistic time The maximum activity time if significant delays are encountered. I Expected time The average activity time. 1 Beta probability distribution A probability distribution used to describe activity times. Crashing The shortening of activity times by adding resources and hence usually in- creasing cost. PROBLEMS The Mohawk Discount Store is designing a management training program for individuals at its corporate headquarters. The company wants to design the program so that trainees can complete it as quickly as possible. Important precedence relationships must be main- tained between assignments or activities in the program. For example, a trainee cannot serve as an assistant to the store manager until the trainee has obtained experience in the credit department and at least one sales department. The following activities are the as- signments that must be completed by each trainee in the program. Construct a project net- work for this problem. Do not perform any further analysis.
