Effort in Project Management – Definition and Meaning
Effort refers to the amount of work (measured e.g. in person-hours or person-days) or the quantity of other resources (such as materials or budget) required to complete a specific task or execute an entire project. It serves as a key basis for resource planning and cost estimation. Effort is typically quantified by considering both the intensity and duration of work or resource use.
Example, Best Practice, and Further Information
In a software project, for example, the estimated effort to develop a new feature might be 40 person-hours. A proven best practice is to estimate effort as realistically as possible, based on historical data from previous projects and expert judgment. This is in line with the estimation techniques in the PMBOK Guide and agile methods such as story points. Careful effort estimation helps create realistic schedules and budgets.
