eliminating Waste thoroughly
In these methods, they identified 3 general forms of waste, which they called in Japanese – ‘Muda‘ (meaning unproductive), ‘Mura‘ (unevenness, inconsistency) and ‘Muri‘ (over-burden, unreasonableness). In doing this, they also identified 7 particular types of waste in manufacturing:
Seven WaStes
Mr Taiichi Ohnols categorization of the seven major wastes typically found at any gemba (workplace)
Overproduction
Producing mores sooner or faster than is required by the next process or customerl
Waiting
Operators standing idle as machines cyck equipment faiIS parts delay etc.
Conveyance
Conveyance itself is waste because it creates no value. Obviously parts and products must be transported, but any movement beyond the absolute minimum is MUDA.
Processing(or Overprocessing)
Unnecessary or incorrect processing.
Inventory
Keeping unnecessary raw materiais, parts, WIP (work in processj)and finished goods. More precisely,keeping more than the minimum stock necessary for a well-controlled pull system.
Motion
Operator making movements that is creating no value.We can also identify waste in the motion of machines.
Correction
