Software Development Waste

Waste in software development includes seven classic types identified by the Poppendiecks: partially done work, extra features, relearning, handoffs, delays, context switching, and defects. Modern research expands this to nine categories, adding wrong features, backlog mismanagement, over-engineering, cognitive load, psychological distress, ineffective communication, and AI-generated code waste. Teams can reduce waste through value stream mapping, WIP limits, cross-functional teams, knowledge-sharing practices, rigorous prioritization, and maintaining team morale. The goal is continuous identification and elimination of non-value-adding activities.
