Is is not analysis frequently asked questions

What is the purpose of "Is-Is Not" analysis in Sigma Magic?

The purpose of the Is-Is Not analysis is to systematically identify the scope of a problem by clarifying where, when, and to whom the issue occurs and does not occur. This helps in narrowing down possible root causes.


How do I access the "Is-Is Not" tool in Sigma Magic?

In Sigma Magic, the "Is-Is Not" tool is available under the Problem-Solving or Root Cause Analysis section. You can navigate to this tool via the software’s menu or by searching for it in the toolbar.


How do I perform an "Is-Is Not" analysis in Sigma Magic?
  • Open the Is-Is Not tool in Sigma Magic.
  • Define the problem statement clearly.
  • Identify what the problem is and is not under various categories, such as What, Where, When, Who, and How.
  • Compare and analyze differences between the Is and Is Not sections to find possible causes.
  • Use the insights to prioritize corrective actions.
    • What are the key components of an "Is-Is Not" analysis?

    The analysis typically includes:

    • What Is & What Is Not – Defining the problem and what is unaffected.
    • Where Is & Where Is Not – Identifying locations where the issue occurs and does not occur.
    • When Is & When Is Not – Noting the timeframe of the problem.
    • Who Is & Who Is Not – Identifying affected and unaffected individuals or groups.
    • How Is & How Is Not – Analyzing the process differences in problem occurrences.
    How does "Is-Is Not" analysis differ from other root cause analysis tools?

     Unlike tools like Fishbone Diagram (Ishikawa) or 5 Whys, which identify causes through brainstorming, the Is-Is Not method helps narrow down issues by making structured comparisons, making it more systematic.




    What should I do if the "Is-Is Not" analysis does not reveal a clear root cause?
  • Re-evaluate the problem definition to ensure accuracy.
  • Involve different teams or departments  to gather diverse perspectives.
  • Use additional tools like Pareto Analysis or Hypothesis Testing in Sigma Magic.

    • Can I customize the "Is-Is Not" analysis template in Sigma Magic?

    Yes, Sigma Magic allows you to edit, modify, and tailor the analysis format based on your industry and specific problem.


    How do I validate findings from the "Is-Is Not" analysis?
  • Cross-check findings with historical data.
  • Use real-time process observations  to confirm trends.
  • Conduct a pilot test  based on your conclusions.

    • What are common mistakes when using "Is-Is Not" analysis?

    ·       Poorly defined problem statement leading to irrelevant comparisons.

    ·       Not involving key stakeholders, resulting in missing information.

    ·       Relying solely on this tool without using additional validation techniques.


    Can "Is-Is Not" analysis handle complex problems with multiple causes?

    ·       Yes, but it is recommended to combine it with tools like Fault Tree Analysis (FTA) or Failure Mode and Effects Analysis (FMEA) for more detailed problem-solving.
