Definition of Network Analysis
Network analysis is a systematic method used in project management and operations research to plan, schedule, and monitor complex projects. It involves breaking down a project into different tasks and organizing them in a sequence to optimize the flow of work, minimize bottlenecks, and ensure timely project completion. The primary techniques used in network analysis include the Critical Path Method (CPM) and the Program Evaluation and Review Technique (PERT).
Examples of Network Analysis
- Construction Projects: For large construction projects, network analysis helps in scheduling all tasks, from foundation laying to final inspection, to ensure the project completes on time.
- Software Development: In software development, network analysis can be used to schedule coding, testing, and deployment phases efficiently.
- Manufacturing Processes: Network analysis helps in planning the production schedule and inventory management in manufacturing, ensuring all processes are optimized and streamlined.
Frequently Asked Questions
Q: What are the key components of a Network Analysis diagram? A: The key components include nodes (representing activities or tasks), arrows (representing the sequence or dependencies between tasks), and critical paths (the longest sequence of tasks determining the project’s shortest possible completion time).
Q: What is the difference between CPM and PERT? A: CPM (Critical Path Method) is focused mainly on determining the critical path for deterministic task durations, while PERT (Program Evaluation and Review Technique) incorporates probabilities for task durations to manage uncertainty.
Q: How is float calculated in network analysis? A: Float, or slack, is calculated as the difference between the latest possible finish date and the earliest possible finish date for a task. It represents the amount of time a task can be delayed without affecting the project’s completion date.

Program Evaluation and Review Technique (PERT): A method used to analyze the involved tasks in completing a given project, especially the time needed to complete each task and the minimum time needed to complete the total project.
Float/Slack: The amount of time a task in a project schedule can be delayed without causing a delay to subsequent tasks or the overall project.
