Timesheets Vs Job cards in Manufacturing

At what time do you use Jobcard over timesheets in Manufacturing.Do you do timesheets for Engineer to order as Projects is attached to the work order? Or do you do jobcards only if you are doing Make to stock or Make to order?

Kindly assist and clarify this bit.Seems vague from all the information i have researched on.

I am using ERP next 12.1.18.
