Question 2

LEAN PRODUCTION

Answer 2

A philosophy of management based on cutting out waste and unnecessary activities
• Overproduction – produce more than customers have ordered.
• Inventory – holding or purchasing unnecessary inventory.
• Waiting – production delays/idle time when value is not added to the product.
• Defective units – production of a part that is scrapped or requires rework.
• Motion – actions of people/equipment that do not add value.
• Transportation – poor planning or factory layout results in unnecessary transportation
• Over processing – unnecessary steps that do not add value.

=> Lean production is closely related to quality practices such as Kaizen, JIT and TQM.

• Systemise – arrange and identify items for ease of use and approach tasks systematically.
• Sanitise – be tidy, avoid clutter.
• Standardise – be consistent in the approach taken.
• Selfdiscipline – sustain by motivation. Do the above daily.
