5Why Analysis Overview

This 5Why Analysis is one problem-solving technique from the lean tool family. Lean is actually coupled with Six Sigma and TPS in its methodology for continuous improvement. This methodology helps the teams dig down and drill deeper to identify the actual root cause behind the issue being dealt with rather than focusing on just its symptoms. In doing this, they work to provide better solutions and their sustainability.

Why 5Why Analysis is Used?

  1. Define the root causes: The process allows teams to target the real root cause of a problem rather than its apparent symptoms. By discovering deeper causes, organizations could make appropriate changes preventing recurrence of the problem
  2. Ease of use: It is user friendly and does not present with need for sophisticated statistical techniques or software. All members of the team can easily access it, thus promoting teamwork and openness.
  3. Cost-efficient: It does not demand many resources hence a cost-effective method to carry out a root cause analysis
  4. Helps in process improvement: It supports Lean principles by focusing on the elimination of waste, inefficiencies, and defects from processes.
  5. Promotes Critical Thinking: The iterative questioning process promotes a culture of inquiry that encourages teams to question assumptions and think critically.
