A couple of weeks ago I finished reading Gemba Kaizen by Masaaki Imai. Just like all the other books on lean manufacturing, I found it extremely rewarding and thought-provoking, while at the same time being somewhat longer and more repetitive than I might have wished (the second half comprises an interminable list of case studies, many of which add very little to the value of the book).
The main idea I took away from the book was that of 5S. This is basically rigorous and institutionalised house-keeping (translated as Sort, Straighten, Scrub, Systematize, Standardize). The idea is that an untidy or disorganised workplace can contribute significantly to reducing the throughput of value for the customer.
Can this concept be applied to software development? I believe so. All our tools have to be readily accessible when needed. Our codebase, workspace and CM system should all be well-organised, and should contain nothing that isn’t needed to add value or promote flow. Our build should be clean and automated, and driven only from components that are CM-controlled. And when we’re working as a team, all our processes and techniques should be standardized so that each person’s actions are understandable by all.
