The triple constraint in Project Management

The triple constraint in Project Management

They are the key attributes that must be handled effectively for successful completion and closure of any project.

These constraints are: TIME…..COST…..SCOPE

If we consider the below scenario:

(Note X, Y & Z are just used for explanation and they represent the units of each e.g: Z TIME = 5 days, X Tasks = 30 tasks & Y Cost = $1000 ->  that means in order to deliver the 30 tasks in 5 days you need $1000 as a cost, etc…)

The below figure represent a triangle that has 2 main dimensions (X, Y & Z)

  • If Z TIME is the required to deliver X Tasks using Y Cost “Budget

THEN

  • Y COST is needed to deliver X Tasks in Z Time

THEN

  • X TASKS can only be delivered if I have Y Cost and in Z Time
  • Quality is the volume of the triangle – To keep the quality the same then any change in one of the triangle dimensions need to have some adjustment in the other 2 dimensions
