The proper way to organise your process planning data is to separate your operation with systemes.
When evaluating the frequency of a task, EWD consider that only one worker is operating under a system.
That mean that in order to have a right ergonomic evaluation, you should devide your planning data so that only one worker is operating under a system.
| Do | Don't |
|---|---|
| Regroupe the operation of a worker under a system | Put all the operation of all the worker under one system |
