THE MAIN ADVANTAGE OF THE PROGRAM EVALUATION AND REVIEW TECHNIQUE (PERT) IS THE PROVISION OF A GRAPHIC MODEL OF ACTIVITIES WITH ESTIMATES OF THE TIME, RESOURCES, PERSONNEL, AND FACILITIES NECESSARY TO ACCOMPLISH A SEQUENCE OF INTERDEPENDENT ACTIVITIES, AS IN PROGRAM IMPLEMENTATION. A PERT MODEL CAN ALSO IMPROVE COMMUNICATION BETWEEN PERSONS AND DEPARTMENTS BY SHOWING THE PRECISE ROLE OF EACH UNIT IN THE PROCESS, AND CAN HELP REDUCE FRICTION IN PROBLEM SOLVING AND ADMINISTRATIVE DECISION MAKING BY REVEALING NECESSARY STEPS. THE STEPS IN DEVELOPING THE NETWORK ITSELF ARE SPECIFYING THE FINAL EVENT OR COMPLETION POINT, DECIDING ON PRECEDENT EVENTS THAT MUST BE ATTAINED, SEQUENCING THESE EVENTS PROPERLY, AND DETERMINING ACTIVITY TIME BETWEEN EVENTS. PERT HAS BEEN SUCCESSFULLY USED IN PLANNING A PROGRAM OF DENTAL CONTINUING EDUCATION, DEVELOPING A TEACHER'S HANDBOOK, AND CONDUCTING VARIOUS PUBLIC HEALTH PROJECTS. HOWEVER, PERT DOES NOT PROMOTE CREATIVITY OR ORIGINALITY, AND MUST FOLLOW THE STAGES OF PROBLEM IDENTIFICATION, FACT FINDING, DETERMINATION OF LONG-RANGE AND SHORT-RANGE GOALS AND OF CRITERIA, AND EVALUATION OF POSSIBLE SOLUTIONS. THE DOCUMENT INCLUDES A PROBLEM-SOLVING FLOW CHART, PERT NETWORK FLOW DIAGRAMS, AND 21 REFERENCES.
