Learn: Critical Path Analysis (CPA): Purpose and Use

Welcome!Welcome to our lesson on Critical Path Analysis (CPA). Building on your knowledge of decision-making tools like decision trees, we'll explore how CPA can enhance business efficiency and strategic planning.

What is Critical Path Analysis?Critical Path Analysis (CPA) is a project management tool used to identify the sequence of tasks essential for completing a project in the shortest possible time. It allows businesses to schedule tasks, allocate resources efficiently, and minimise delays.

Why is CPA important?CPA helps businesses reduce wasted time and resources by focusing on tasks that directly impact project completion. It is particularly useful for large, complex projects with multiple interdependent activities.

Key Components of CPACPA uses a visual diagram called a network diagram. This diagram shows all tasks required for the project and the order in which they must be completed.Each task is represented by a box, called a node, and arrows show dependencies between tasks.

How does CPA work?CPA involves several steps:List all tasks needed for the project.Estimate the time required for each task.Identify dependencies between tasks.Create a network diagram showing tasks and dependencies.Determine the critical path and calculate float for non-critical tasks.

Benefits of CPACPA ensures efficient planning and scheduling, minimises delays, and helps allocate resources effectively. It provides a clear overview of the project and highlights tasks that require urgent attention.

Limitations of CPAAlthough useful, CPA has limitations. It assumes accurate task durations, which can be difficult to predict. It also doesn't account for unexpected changes or risks during the project.
