Left of the Loop: The Gymnasion

The article discusses the importance of testing and understanding a tool before committing to a specification. It uses the example of the ancient Athenian gymnasion, where young men were trained in physical readiness and civic judgment together. This approach is contrasted with modern practices, where teams often separate testing and understanding, leading to inaccurate specifications. The article emphasizes the need for teams to build shared calibration and judgment through real-world testing before committing to a spec.
