2. Introduction to PERT
“Project Evaluation and review Technique"
 Schedules method originally to plan of
manufacturing project.
 Employs a network interrelated activities.
 Coordinates optimum cost and time criteri
a.
 Emphasizes the relationship between time
each activity takes and cost associated
for the completion of the entire project.

3. Applications in Project Management
 PERT is used to plan, schedule and
control a wide variety of project:
• R & D of new products and processes
• Construction of buildings and highways
• Maintenance of large and complex
equipment
• Design and installation of new systems

4. Example: Riverwalk Associates
 Riverwalk Associates is in the business of building
elaborate parade floats. Its crew has a new float to
build and want to use PERT to help them manage
the project .
 The table on the next slide shows the activities that
comprise the project. Each activity’s estimated
completion time (in weeks) and immediate
predecessors are listed as well.
 The project manager wants to know the probability
to complete the project in 26 weeks, the possible
activities and find which activities is the critical path.

F 4 1/9

7. Project Network(Activity-On-
Arrow)
 The possible paths are-
 A-D-J = 14
 A-E-I-K = 17
 A-C-F-H-J = 22
 A-E-H-J = 16
 A-E-I-K = 17
 A-C-F-I-K = 23
 B-G-K = 11
 B-F-H-J = 17
 B-F-I-K = 18

8. Contin.
 We got the critical path A-C-F-I-K = 23 weeks
 = tp – to2 = 1.41

 Calculating the probability to complete the project
within the stipulated time(26 weeks)-
Z = (TA - TE)/ = (26-23)/1.41= 2.12approx.
In accordance to the 50% table,
Table value= .4830
= .4830+.5 =.9830= 98.30%
Therefore the probability for completing the project
within 26 weeks is 98.30%.
