Any code is, therefore, somewhat flawed, so errors and inefficiency are an inescapable pathology in software development. Accordingly, technical debt naturally compounds as more code is written. Some of the more expensive technical realities of modern application development are listed here:

• There are rigidly coupled components that do not easily allow change at either the technical level or the business level. Allowing such unprincipled interpenetration leads to complex capillary networks growing throughout the body of your code. The edges of these networks are nearly impossible to trace, concretizing entanglements that ...
