Effort and Duration Calculations

Washington, District Of Columbia, United States 

A project's effort and duration are interrelated, as is reflected in their calculation within the model. Effort drives duration, notwithstanding productivity-related feedback between duration constraints and effort. The basic effort equation is:

K = D^{0.4}*(\frac{S_{e}}{C_{te}})^{1.2}

where,

Se is effective size - introduced earlier. Cte is effective technology - a composite metric that captures factors relating to the efficiency or productivity with which development can be carried out. An extensive set of people, process, and product parameters feed into the effective technology rating. A higher rating means that development will be more productive. D is staffing complexity - a rating of the project's inherent difficulty in terms of the rate at which staff are added to a project.

Once effort is obtained, duration is solved using the following equation:

t_{d} = D^{-0.2}*(\frac{S_{e}}{C_{te}})^{0.4}

The duration equation is derived from key formulaic relationships. Its 0.4 exponent indicates that as a project's size increases, duration also increases, though less than proportionally. This size-duration relationship is also used in component-level scheduling algorithms with task overlaps computed to fall within total estimated project duration.
