There are several aspects of any task in a schedule. Start date, Finish date, type of activity, the resources required for the task, the amount of resource effort required to accomplish the task, the quantity of work to be executed, and so on.

The quantum of work to be executed is incorporated by way of budgeted units of resource (material) and the same translates into amount of effort required (labor and non-labor). There’s a certain value of hours or days needed to complete 1,000 cubic meters of a task. So two things are involved here … 1,000 cu.m of task itself (quantity) and ‘n’ effort (mandays, manhours, etc.) to perform this quantity.

e.g., 100 sqm of plaster @ 8 sqm per mason per day = 12.5 mandays.
In this example;
100 sqm is the amount (quantity) of work to be performed,
12.5 md is the amount of effort involved.

If this quantity is to be executed in 10 days, daily resource (mason) allocation required = 1.25 (= 12.5 / 10) nos. => 1.25 x 8 = 10 sqm daily output.

*Note: The above is only an example for illustrative purposes. Assumed productivity is not to be considered standard.
