The Iron Triangle of Project Management
Balancing Your Budget, Scope and Schedule
(Also Known as The Triple Constraints of Project Management)
Imagine that you're managing the rollout of a new brand logo for your organization. At first, everything's going great. But, after a few weeks, some issues start to crop up that take you down a different path.
First, you realize that you've forgotten to factor in some costs in the printing and manufacturing process. Then, a few other tasks take longer to complete than you predicted.
You could recruit some additional contractors to get the rollout done on time. But, that will mean reducing the budget elsewhere. You consider not spending the extra amount on printing and manufacturing, but this might mean that you have to reduce the scope of your project, or push back the launch date.
