management, the effort plays a decisive role in the various evaluation criteria. It is a question of how much effort is required to achieve the project objective or a sub-objective. In project management, effort is understood as a quantifiable number of work units in which a planned activity, a subproject or the entire project is to be realized. Effort is usually expressed in hours, days, weeks, or months, from which labor costs can be determined. It can refer to an individual employee or a team. Effort plays an important role in determining the Earned Value (EV) and Earned Value Management (EVM), among other things.
