Root Cause Analysis

Turns workflows, data, causes, and improvements into a tangible result by describing the problem precisely, collecting data and events, and deriving countermeasures and controls.

Core question
Which systemic causes caused or enabled the problem, and which countermeasures prevent recurrence instead of only treating symptoms?
MediumWorkshop + async1-4 h
Purpose

The method helps clarify workflows, data, causes, and improvements in a concrete way. It looks for patterns, causes, weak points, or bottlenecks and derives measures from them. The result is captured as a problem statement, cause hypotheses, and confirmed causes.

How it works

The team follows the steps: describe the problem precisely, collect data and events, structure possible causes, test causes with evidence, and derive countermeasures and controls. Each step is captured visibly. At the end, a problem statement, cause hypotheses, and confirmed causes are available so decisions, tests, or actions can follow directly.

Ideal for

  • Recurring operational problems
  • Quality and service deviations
  • Post-incident reviews

Not good for

  • Trivial one-off errors
  • Blame assignment
  • Situations without solid data

Deep dive

In detail

Root Cause Analysis separates visible symptoms from the conditions that enable or trigger a problem. The method combines events, data, process steps, and human factors into a traceable causal logic. Many possible explanations are narrowed down to plausible causes before measures are defined. That creates a shift from quick repair to durable improvement.

Facilitation

Prepare the problem statement, data, timeline, and people involved in the process. Moderate in a fact-focused way and keep observation, interpretation, and hypothesis visibly separate. Do not stop at the first plausible cause and assign actions only to confirmed causes.
