PERT--Program Evaluation and Review Technique--is introduced in this programed text to enable the reader to work at his own pace to gain a mastery of the basic rules of PERT and their application. Some of the operations the reader will be able to perform upon completion of the program include: applying PERT techniques to projects of any type or size, defining a PERT event and a PERT activity, listing the information necessary to construct a PERT network, constructing a PERT network (diagram) and a PERT analysis sheet (computer output sheet), looking at a PERT network or PERT analysis sheet and determining whether events are on schedule, formulating a new schedule should an existing schedule become impossible to meet, identifying areas of potential disturbances so that positive action may be taken to offset the identified disturbances, and re-evaluating the project and making decisions as to up-grading the priorities of the critical path to insure completion on time.
