To finalize the solution, ensure that it is permanent and institutionalized by:

  • Validating the solution

  • Training the affected groups in the new process and procedures

  • Sharing lessons learned


Verification versus Validation:

  • Verification: Was the solution built right?
  • Validation: Was the right solution built? (Or: Have the desired outcomes or effects been realized?)
  • Things to check:
    • Does the outcome meet expectations?
    • Does it work for all possible conditions?
    • Does it create any new problems?
    • Do customers agree with (or at least accept) the solution?
    • Has the solution affected suppliers?


  • If the solution has lead to changes in procedures or systems have changed, those using the systems will need training on how to work with the changes.
  • Most likely, informal training has been conducted as part of the solution implementation and verification. Now is the time to develop a formalized training program around the new system.
    • Who, how and when will users be trained?
    • How will suggestions for potential revisions or enhancements be collected and used?

Knowledge transfer

  • Identify other processes that are similar; the same root cause analysis solutions may apply to them.
  • Leverage best practices by considering a Knowledge Base to archive and retrieve best practices.
  • Mitigating a root cause creates a best practice; publicize best practices through (internal) forums, newsletters or blogs.
