Finally, engineers will differ in their levels of skill and commitment to architecture. Sadly, architecture has been undervalued for so long that many engineers regard life with a BIG BALL OF MUD as normal. Indeed some engineers are particularly skilled at learning to navigate these quagmires, and guiding others through them. Over time, this symbiosis between architecture and skills can change the character of the organization itself, as swamp guides become more valuable than architects. As per CONWAY’S LAW [Coplien 1995], architects depart in futility, while engineers who have mastered the muddy details of the system they have built in their images prevail. [Foote & Yoder 1998a] went so far as to observe that inscrutable code might, in fact, have a survival advantage over good code, by virtue of being difficult to comprehend and change. This advantage can extend to those programmers who can find their ways around such code. In a land devoid of landmarks, such guides may become indispensable.
