Labour Demand Charts

Labour Demand Charts are generated based on the current, filtered view of your project schedule and indicate what effort is required to support your plan (either in hours/time-period or full-time equivalents/time-period).   The time scales for the labour demand chart are fully configurable and so is the size and appearance of the chart. Multiple charts can be generated for comparison and this can be useful to determine the effects of changing task parameters, such as dates,  task duration or estimate to complete (ETC).

Calculation of Labour Demand data

The labour demand data is based upon the task durations and Estimates to Complete (ETC) for all activities in the filtered view your schedule that have an ETC > 0. Hours for each task are distributed evenly across all of the remaining duration.  i.e if a 5 day task has an ETC of 40 hours, it will contribute an average demand of 8 hr/day distributed between the start and finish day of the task towards the overall labour demand calculation.  All calculations are also referenced against the Gantt Chart data date according to the following rules:

For Task 1, both start and finish dates are prior to the data date. In this case, demand calculation is based upon setting an equivalent start date = data date and the finish date = data date + task duration.

For Task 2, only the start date is prior to the data date. In this case hours are distributed between the data date and the task finish date i.e. the data date is effectively used as the start date to determine the remaining duration of the task.

For Task 3, both the start and finish dates are later than the data date. In this case the hours are distributed between the task start and finish dates.
