These notes talk about what critical path analysis is and why a business might use a critical path analysis when planning out tasks for a project. Also outline the rules for completing a critical path analysis diagram.
Critical path analysis (CPA) – A project analysis and planning method that allows a project
to be completed in the shortest possible time.
Why businesses need to plan complex projects?
Many larger businesses get involved in projects that are complex and involve
significant investment and risk.
As the complexity and risk increases it becomes even more necessary to identify the
relationships between the activities involved and to work out the most efficient way
of completing the project.
Information needed for CPA:
A list of all activities required to complete the project
The time (duration) that each activity will take to completion
The dependencies /pre-requisites between the activities (e.g. activity D cannot be
completed until activity B and C done).
EST – Earliest Start Time
LFT – Latest Finish Time
