What is the Triple Constraint?
The triple constraint of project management is the balance of the project’s scope, time and cost. Triple constraint is used to determine whether or not a project’s objectives are being met. During the planning phase of a project, a project manager will define the scope, time, and cost of a project. As the planning phase continues, the project manager discovers that there may be some changes or adjustments needed in the project’s scope, time and/or cost. When one aspect needs change or adjustment, then it directly affects one of the other factors of the triple constraint. For example, if the cost increases, it is logical to assume that the scope and time will increase as well. Or, if the cost decreases, one can assume that the scope and time will decrease. This rings true for scope and time as well. A project manager must be thorough and detailed in planning the scope, time and cost of a project in order to maintain the constraint or be prepared to fluctuate with it. Adjustments can be made during the project for various reasons to include changes made by the client as well. It is the project manager’s responsibility to be aware of the changes and how they will affect all aspects of the triple constraint and be prepared to modify each aspect accordingly.
The scope of the project is what is actually included in the project as well as what is to be excluded. A project’s size, how complex it is and its importance all affect how much effort goes into scope planning. Defining the scope of a project is important in determining the success of the project. A detailed scope overview and statement is the basis for project decisions. It helps those involved understand exactly what the outcome of the project will look like and what is to be expected.
