Workload Analysis

Excessive workload has been identified as a contributory factor to several major accidents. For example, during the Three Mile Island Nuclear Power Plant disaster, control operators tried to cope with several hundred alarms within a few minutes, whilst under the pressure of bringing the plant under control. It is clear to see that this exceeds human capability.

Workload analysis is used to answer key questions such as “how much is too much workload for an individual to cope with?” or, conversely, "when are workload levels too low?"

The Keil Centre can help organisations to apply the relevant tools to analyse these issues, either using workload prediction or workload measurement techniques.

Workload analysis is used when assessing an existing operation, a future operation or to assess the impact of organisational change.

We can also apply staffing assessment techniques to test the current or proposed staffing arrangements. We can use other analysis techniques to determine staffing requirements to build a profile of the staffing numbers required.

The benefits of workload and staffing analyses include:

  • Reduced likelihood of inappropriate manning staffing
  • Reduction of potential factors contributing to human failure
  • Identification of more efficient ways of working

 

Workload Prediction

Workload prediction starts by identifying tasks undertaken over time to create a timeline analysis which can then be overlaid with modelling calculations to provide a prediction of workload over time. This can be used to investigate excessively high or low workload and resource conflicts.

Some description

Workload Measurement

We also use a range of validated methods, such as NASA Task Load Index (TLX), to measure the workload associated with a particular task.  Such methods can measure workload on a number of dimensions and take account of factors such as mental and physical demands, time pressures and frustration levels.  This method can be useful for many applications, including Human-Machine Interface (HMI) design and control room layout.

We can also apply manning analysis techniques to determine manpower requirements, which can be used to build a profile of the staffing numbers required.

Who is it for?

Workload analysis techniques may be used by those responsible for operations, and / or the implementation of new or modified systems, equipment or ways of working.
