Percent complete is a measure used in project management to quantify the progress of a project. It is defined as the earned work hours or dollars for all accounts divided by the budgeted work hours or dollars for all accounts. This metric provides an indication of how much work has been completed in relation to the total planned work.
Option B: Cost to complete refers to the estimated cost required to finish all remaining project work.
Option C: Earned value is a key metric in Earned Value Management (EVM) that represents the value of the work actually performed.
Option D: Forecast refers to predicting future project performance and outcomes based on current data and trends.
Therefore, A. Percent complete is the correct answer as it accurately describes the ratio of earned work hours or dollars to budgeted work hours or dollars.
