Benefit/ cost analysis The process of determining the pros and cons of any project, process, product or activity. Benefit/ cost ratios These models examine the cost-to-benefit ratio. Change control board A board that determines the validity and need of (thus approving or denying) project change requests.

Constrained optimisation methods These are complex mathematical formulas and algorithms that are used to predict the success of projects, the variables within projects and the tendencies to move forward with selected project investments. Examples include linear programming, integer algorithms and multi-objective programming. Constraints Any influence on the project that may limit the options of the project team in performing the project work. Decomposition A planning
