Why Quality Management System practice is necessary In Industrial and non-Industrial facilities within enterprise as well as in corporate level?

TQM implementation is must based on the fact that (i) malfunctioning of system due to not following the correct quality procedures, (ii) not making the employees aware of quality management system resulting the poor work culture ending up with huge financial loss, (iii) High risk working condition does arise when system runs without quality ethic, (iv) System start running is a slower pace without Quality Management System implementation as like a Personal Computer is run with an anti virus installed in it and so on. There are uncounted concerns on this subject to realize the requirement of the stated management practice.
