Minggu 4 PERT

Introduction

This tutorial provides a detailed overview of the fourth week's topics covered in the Operations Management course for semester 3 students at the S1 Management program of FEB UNTIRTA. The aim is to break down the key concepts discussed in the video into actionable steps for better understanding and application.

Step 1: Understanding PERT (Program Evaluation and Review Technique)

• PERT is a project management tool used to plan and coordinate large projects.
• It helps in identifying the minimum time needed to complete a project.
• Key components of PERT include:
  • Events: The milestones in a project.
  • Activities: The tasks that must be performed to move from one event to another.
  • Time Estimates: Each activity has three time estimates:
    • Optimistic time (O)
    • Pessimistic time (P)
    • Most likely time (M)

Practical Tips

• Gather all necessary data on project activities and their durations.
• Use a PERT chart to visualize the project timeline and dependencies.

Step 2: Calculating Expected Time

To calculate the expected time (TE) for each activity, use the formula:

TE = (O + 4M + P) / 6

• This weighted average accounts for uncertainty in time estimates.

Practical Advice

• Ensure that your estimates are realistic and based on previous experiences or data to enhance accuracy.

Step 3: Developing the PERT Chart

• Identify all the project activities and their dependencies.
• Create a visual representation using the following steps:
  1. List all events and activities.
  2. Connect activities with arrows to indicate dependencies.
  3. Label each activity with its expected time.

Common Pitfalls

• Failing to accurately define dependencies can lead to an incorrect PERT chart.
• Overestimating or underestimating activity times can skew project timelines.

Step 4: Analyzing the PERT Chart

• Identify the critical path, which is the longest path through the project with the least amount of slack.
• The critical path determines the shortest time to complete the project.

Application

• Use the critical path to prioritize tasks and allocate resources efficiently.
• Regularly update the PERT chart as project conditions change.

Conclusion

This tutorial outlined the essential steps for effectively using PERT in project management. Understanding and applying these concepts can significantly improve project planning and execution. For further exploration, consider practicing with real project scenarios to enhance your skills in using PERT charts and analyzing project timelines.
