What is meant by 'muri' in lean terminology?

  1. Waste

  2. Overburden

  3. Inconsistency

  4. Value-added work

The correct answer is: Overburden

In lean terminology, 'muri' refers specifically to overburden or excessive strain on employees, equipment, or operations within a process. The concept highlights the importance of avoiding undue stress that can lead to inefficiencies, errors, and ultimately waste. When resources are pushed beyond their limits, it can result in lower quality output, increased downtime, and decreased employee morale, which can significantly impact overall operational effectiveness. Addressing 'muri' is crucial for maintaining a balanced and sustainable workflow. By recognizing and mitigating overburden, organizations can optimize processes, enhance productivity, and create a healthier work environment, which is a core principle of lean thinking. This understanding is key to effectively implementing lean practices to continuously improve reliability and maintenance strategies.
