D. The project achieved the triple constraint plus the one internal condition.

D. The project achieved the triple constraint plus the one internal condition.

Explanation:

The triple constraint theory in project management says every project operates within the boundaries of scope, time, and cost. A change in one factor will invariably affect the other two.

Just as restrictions enhance creativity, the triple constraint provides a framework that everyone in the project can agree on. ... The triple constraint is a model that helps project managers know which trade-offs are going to work and what impact they'll have on other aspects of the project.

The triple constraint theory, also called the Iron Triangle in project management, defines the three elements (and their variations) as follows:

Scope, time, budget.

Scope, schedule, cost.

Good, fast, cheap

a manufacturer of printed circuit boards uses exponential smoothing with trend to forecast monthly demand of its product. at the end of december, the company wishes to forecast sales for january. the estimate of trend through november has been 200 additional boards sold per month. average sales have been around 1000 units per month. the demand for december was 1100 units. the company uses α = 0.20 and β = 0.10. make a forecast including trend for the month of january.
