What is the triple constraint?
To successfully plan and execute a project, the budget must be kept, resources optimally utilized, and the product delivered to expectations – and all that while constantly managing the changes that arise in the course of a project. To achieve this, it’s necessary to create a balance between the factors time, cost, and scope. Scope is sometimes also referred to as goal, content or quality.
The triple constraint helps visualize these three factors and makes clear that when one factor changes, at least one of the other two will be affected. If a deadline needs to be moved forward, for example, it may be necessary to use more resources and costs may increase. In addition, the risk increases that the delivered product will not satisfy stakeholders.
