• Evaluate the relationship between muri, muda, and mura in the context of lean management principles.
  • In lean management principles, muri, muda, and mura are interrelated concepts that address waste and inefficiency. Muri represents the overburdening of people or processes, which can lead to muda—waste caused by ineffective resource use. Mura highlights the unevenness in workloads or processes that contributes to both muri and muda. By recognizing these connections, organizations can implement comprehensive strategies that target all three elements, creating a more efficient and balanced system that enhances overall productivity.
