Dear JayDG,
You have written that "Thanks Dinesh. Time & Motion study was a good methodology but no longer relevant today specially in multi-tasked complex process specially in a very large manufacturing company. No, such a study is not possible in this case here."
I am little surprised at the outright rejection. Multi-tasking cannot be impediment to the time and motion studies. On what parameters you assess the relevance of this method, would you mind to share? If you had done this study long ago, you would have started giving prominence to the processes rather than persons. With non-availability of the processes, person has acquired importance.
Famous company, McDonald has measured their work activities. Unit of measurement is not just minutes but seconds as well. Famous company Bosch (erstwhile, MICO) has measured 150,000 production processes. Yes, I mean 150,000 and there is no typing error. However, if you dismiss importance of the time and motion studies in a flash, it tantamount to throwing baby with bath water.
By the way, would you mind to share what is the complexity of your production processes? Secondly, how do you measure the efficiency of your plant? What KPIs do you use? You may check the following link:

Anyway, other members may contribute their opinions.
Ok...
