# @6 j- J- R! `; b, f! Z' W# j4 dDon't do it! Simulation can be a powerful influence on decision-makers. If you reach conclusions based on a faulty model, you've done a greater disservice to your organization than if the simulation had not been performed at all.
Think about a test plan early in the project and revise it as you progress. Delivering a "state of the model" assessment, which grades the various segments of the model regarding quality and completeness, should be a standard part of your simulation project at each milestone.
