What is CPM, Critical path method, What is float?

The critical path consists of the longest sequence of activities from project start to finish

Critical path helps one to focus resources, as some tasks, with float, can be delayed without making the project longer

Float, defines the amount of time a task can be delayed without causing a delay in project or next task

Let's say our project is to make an omelet

What are critical and non critical steps in this project?

Our steps in making an omelet are beat the egg, heat oil in a pan, add the salt, and cook the egg

Beating egg, heating oil and cooking are critical steps but adding salt is non critical, It can be done any time without impacting the project time

Task with float is adding the salt

Critical path tasks must be completed to ensure the project is finished by a certain time
