Which of the following has goals that include just in time delivery, production load levelling, standardised work and right sized equipment?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Kaizen
Option (1) Lean Manufacturing — Incorrect. Lean Manufacturing is a management philosophy that cuts seven wastes, such as overproduction, waiting time and scrap. Its focus is waste.
Option (2) Kaizen — Correct. Kaizen is a Japanese word meaning 'change for better'. It improves productivity step by step. Its goals include elimination of waste, just in time delivery, production load levelling, standardised work, paced moving lines and right sized equipment.
Option (3) Just In Time Manufacturing — Incorrect. JIT is an inventory management strategy. It reduces in-process inventory and its costs, using KANBAN signals. Just in time delivery is only one of Kaizen's goals; load levelling and right sized equipment are not JIT's.
Option (4) Six Sigma — Incorrect. Six Sigma is a data driven approach that reduces quality variations. It allows not more than 3-4 defects per million opportunities. Its aim is fewer defects, and these goals are not listed for it.
