Pareto Analysis

A Pareto chart ranks categories by a common amount and shows their cumulative share of the total. It helps identify the largest observed contributors.

Read freely. Creating a worksheet requires a verified free beta account. No payment or manual beta approval.

When this tool helps

Use it when events or impacts can be grouped into meaningful, consistently defined categories.

It helps a team focus investigation where the recorded impact is greatest instead of selecting the most memorable incident.

When to choose another method

Use a Control Chart for time patterns or Fishbone for possible causes. A Pareto chart of problem categories is not a causal analysis.

How to use it in CI Tools

Read the guide and agree the question, definitions and required starting information.
Open a separate blank worksheet or the built-in synthetic practice sample. Follow the tool-specific steps and review its warnings.
Check the interpretation and save an editable .citools file to your computer. Keep reports as separate exports.
