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?
- 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.
