Final answer:
The given statement is false. The classic triple constraint standard for project performance is composed of time, cost, and scope.
Step-by-step explanation:
The given statement is false.
The classic triple constraint standard for project performance in project management is composed of time, cost, and scope, not client acceptance. The triple constraint refers to the relationship between these three factors in a project, where any change in one factor will affect the others. If the time frame or costs increase, it may require adjustments to the scope of the project.
For example, if a project's deadline is shortened, the cost or resources required to complete the project on time may increase, or the scope of the project may need to be reduced to meet the deadline and budget.
