Unevenness or variability.

Unevenness or variability.

• A. Muri
• B. Mura
• C. Nesting
• D. Pacemaker

Answer: (B)

Mura means unevenness or variability in production. It happens when workloads swing because demand, process times, or setup durations aren’t balanced, creating bottlenecks and idle capacity. When production isn’t leveled, flow becomes irregular, leading to longer lead times and higher inventory. The remedy is to level production (heijunka), set a steady takt time, and implement standardized work to smooth the workload. In this framework, Muri is overburden and Muda is waste; nesting and pacemaker aren’t the terms used for this concept.
