When I am working on a problem, I never think about beauty. I think only of how to solve the problem. But when I have finished, if the solution is not beautiful, I know it is wrong.—attributed to R. Buckminster Fuller

In this chapter we are going to discuss a number of issues that must be considered when designing and developing modifications for Microsoft Dynamics NAV. We will also consider the differences between a minor enhancement and the creation of a new subsystem. Further, we will explore the NAV processing flow and explain how to design modifications compatible with the unique NAV structure.
