仿真误区3：Testing at the end of the project

focuscon

As with analysis, verification of the model must be performed throughout a project. Because it's even more tedious and uninteresting than analyzing the simulation, it's easy to leave testing for late in the project.

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.
