In order for something to be designed it must be the result of an evolutionary process: One that results from aberration, mutation and adaptability. In this sense, a work is not designed if it is necessarily free of all aberration and potential mutation. In order to provide the opportunity of mutation, one must not only adapt to risk, but even encourage it.

When we consider the evolution of an artifact however, the workmanship of certainty is static, whereas the workmanship of uncertainty is most likely to generate innovation. Like any form of evolution, craft can only advance through mutation. Risk provokes an evolutionary mutation through the necessitated gesture of reconciliation of accident.
