These are the sorts of questions you could ask.

Is the way we carry out a task creating more waste than is necessary?

Is someone else simply repeating what you have already done?

Does finishing a task early create more waste ?

Could introducing a resource monitoring system assist in identifying waste minimisation opportunities and reduce unnecessary wastage?

Could timely quality checks detect faults and reduce wastage?

Are short cuts taken as a result of fluctuations in customer demands which may increase impacts in order to fulfill contracts?
