+Figures 3 shows a basic review process and Figure 4 represents a full review process.  The former would be used in a standard context that is familiar to those working on the type of model.  The latter would be used in an innovative situation where there might be significant uncertainty, complexity and/or where the context is safety critical - e.g. nuclear power installations. Results verification is always needed but in standard contexts validation may not need deep consideration and sensitivity analysis may not be required.  In a complex innovative situation very careful attention to all the review activities may be essential.

 * Set up the data with a simple loadcase (a checking loadcase) and carry out a results verification.

-Continue with development/production runs.   Do quick qualitative verification on a regular basis and further quantitative checks as appropriate.  Continue to consider model validation issues if the model is altered and to interpret validation information from the results if practical.
