Workload is a measure of the demands imposed by a system on someone’s mental or physical resources.  

 

The ability to predict workload allows us to analyse design concepts without the need for formal trials.  

 

We can then:

  • Allocate functions rationally between operator and machine

  • Indicate which tasks impose the highest and lowest workload

  • Select the system design that optimises workload

  • Suggest design modifications to optimise workload

  • Avoid the pitfalls of overloaded or underloaded workers
