The document discusses the 7 wastes of software development as identified by Taiichi Ohno, the father of the Toyota Production System. The 7 wastes are: partially done work, extra features, relearning, handoffs, delays, task switching, and defects. It states that the waste created by a defect increases over time if the defect lies undetected. Each waste is then briefly defined, with partially done work becoming obsolete before completion, extra features being unnecessary "pet features", and relearning occurring due to poor documentation. Handoffs between teams should be reduced, delays stem from waiting for resources, and task switching and defects both create waste.
