Root Cause Analysis for Lean Problem Solving

Fishbone analysis, directly in the project

eKaizen currently supports Fishbone (cause-and-effect) diagrams as a structured way to analyze why problems occur. Teams can capture, group, and discuss causes visually, keeping the focus on cause–effect logic rather than assumptions.

This helps teams align on the problem before deciding how to address it.

Work with real causes, not abstractions

Causes are documented directly in the Fishbone structure, making relationships visible and discussions more concrete. This supports collaborative problem solving and shared understanding across the team.

The result is a clearer picture of the problem, grounded in observable causes rather than symptoms.

One method, used consistently

Using a common Fishbone structure supports consistent problem solving across projects, teams, and sites. Terminology can be adapted to company standards while the analytical approach remains the same.

Additional root cause analysis methods, such as 5 Whys, can be added later within the same framework.
