Would like to compare TQM,BRP and Best Prac.Like to know when do i need to use them in specific situation?

Answer 1

TQM is an all encompassing approach to assurance of quality.

The difference between it and Best practice has to do with diligence. What is the definition of "Best Practice" and who defined that standard? Generally what you walk into is that by using "Best Practice" you are inviting your customer to define that, and then risking their lack of satisfaction if you fall short of this uncommunicated expectation.

TQM puts all the cards on the table. It is then incumbent upon the customer to read the TQM manual or system and discuss its adequacy. A much better situation for all.

You'll have to identify BRP for me.
