Two-Value Resource Utilization – Shortage and Coverage Separated

Two-value resource utilization in the capacity view

Shortage and free capacity visible at the same time
Shortage and free capacity visible at the same time

From Rillsoft Project 9 onwards the personnel capacity view displays two values simultaneously: the maximum resource shortage and the average resource coverage per time unit. Bottleneck and free capacity are therefore distinguishable – no netted average is hiding the problem any more.

How does demand and availability matching work?

In Rillsoft Project the professional skills of every employee are stored in the resource pool and matched against the requirements of the project activities. Personnel resources are then proposed based on qualification and taking working and non-working times into account. The personnel capacity view delivers the interactive overview.

What changed compared to Rillsoft Project 8

In older versions only one netted resource-demand value was displayed per time unit. Example:

  • A calendar week has 2 person-days missing
  • The same week has 1 person-day free
  • Rillsoft Project 8: result -2 + 1 = -1 person-day for the whole week

This averaging logic hides the fact that a bottleneck and free capacity exist at the same time.

The two values in Rillsoft Project 9

ValueMeaningExample above
Maximum resource shortagelargest bottleneck inside the time unit-2 person-days
Average resource coveragefree capacity inside the same time unit+1 person-day

The capacity view therefore shows -2/+1 person-days for a calendar week – both statements are immediately readable.

Practical benefit for workforce planning

  • Bottleneck and reserve are visible at the same time
  • Activities can be redistributed instead of overstaffed
  • Decisions about overtime, subcontracting or rescheduling are data-driven
  • The display also works across projects in the multi-project portfolio

Frequently asked questions(FAQ)

From Rillsoft Project 9 onwards the capacity view displays two values in parallel: the maximum resource shortage and the average resource coverage per time unit. Bottleneck and free capacity are visible at the same time – no single netted value any more.

Older versions displayed only a single netted resource-demand value. If two person-days were missing in a week and one was free, the result was -1. From version 9 onwards the view shows -2/+1 instead – shortage and over-coverage are clearly separated.

A netted value hides bottlenecks. With the separate display planners see that staff is missing on some days even though reserves exist in the same period – they can redistribute the activity instead of buying extra resources.

In the example with two missing and one free person-day per calendar week the capacity view shows -2/+1 person-days. The first value is the maximum shortage, the second the average coverage in the same time unit.

Yes. The display is based on the shared resource pool and applies in every capacity view – including the multi-project portfolio with Rillsoft Integration Server or Rillsoft Cloud.
