2.5 Managing Complexity

The single biggest challenge, when programming at scale, is managing complexity. What do we mean by complexity? The literal meaning is derived from weaving together. In programming it refers to the resulting behavior that emerges from combined interaction. As the number of parts and their dependencies increase, the resulting behavior increases exponentially and very soon it reaches the point where it is no longer humanly possible to know and understand it. As a result making changes will inadvertently lead to unknowingly interfering with those interactions and defects are introduced. With increasing complexity existing techniques, methods and paradigms no longer suffice to enable the programmer to adequately manage it. Dezyne offers both encapsulation as well as abstraction of interaction. Interaction which is unencapsulated in other paradigms. By encapsulating and abstract Dezyne manages complexity.
