Guide to PERT Chart in Project Scheduling
Importance: PERT (Program Evaluation Review Technique) chart is a project scheduling tool that helps efficiently plan and coordinate tasks within a project. It enables project managers to estimate the shortest time possible for completing a project by visualizing tasks sequence and duration. This promotes optimal resource allocation and risk assessment.
What it is: A PERT chart is a graphical representation of tasks involved in a project. It usually depicts the timeline, sequencing, and dependencies between tasks. Circles or rectangles (nodes) are used to represent tasks, while arrows show the sequence and dependencies.
How it Works: PERT Chart works on the critical path analysis which means it identifies the longest stretch of dependent activities and calculates them from start to end. Dependent tasks must be completed in a specific sequence. If even one task is delayed, it will delay the entire project. This critical path enables managers to focus resources and potential improvements on crucial tasks.
Answering Questions: When dealing with PERT Chart questions in an exam, it's essential to understand the basics of the chart — how it's constructed, how to interpret it, and how to apply it to real-life situations. You'd generally be asked to either complete an existing PERT Chart or create a new one based on the information given. Remember, the key points are understanding dependencies and the sequencing of tasks.
Exam Tips: For answering questions accurately on a PERT Chart:
- Always calculate and double-check the earliest and latest start and end times.
- Make sure to follow the arrows representing dependencies between tasks.
- Correctly identify the project’s critical path. A delay in critical tasks will hinder the entire project timeline.
- Apply the PERT time estimation formula, if required. The formula is (Optimistic time + 4x Most Likely time + Pessimistic time) / 6.
- Practice diagrams before an exam to familiarize yourself with chart interpretation and creation.

Pert Chart practice test
Project Evaluation and Review Technique (PERT) is a tool that represents tasks and timelines in a graphic format. Unlike the CPM, the PERT Chart focuses on time variables and helps visualize the interrelation between different tasks and activities. It involves the critical examination of completed projects to gain insight for future projects. PERT charts enable project managers to calculate a realistic timeframe for project completion by considering the best-case, worst-case, and most likely case scenarios.
