The Art and Science of Fixing Things
Price: $35 by David Hartshorne and John Allen

Copies:

The framework developed in this paper more thoroughly describes the actual cognitive process involved in fixing machines than any of the individual methodologies generally taught. It is closely related to the scientific method, but focuses on the specific application of improving machine performance and reliability. Rather than describing a detailed prescriptive methodology, we have described fundamental principles that have been well researched. These principles should be strategically and tactically embedded in the process of improving machine performance and reliability, whether the objective is refinement, redesign or reengineering.
