Productivity is about defining and measuring impact, not just focusing on inputs.Internal productivity involves incremental delivery, unblocking yourself, and acquiring foreknowledge and experience.Incremental delivery emphasizes releasing work frequently and breaking tasks into smaller pieces.Unblocking yourself involves actively seeking solutions and asking for help when needed.Acquiring foreknowledge and experience helps in responding effectively to situations by expanding knowledge boundaries.External productivity aligns work with impact, measures unknowns, and involves knowing your timeline.Aligning work with impact helps bridge the gap between technical work and business importance.Measuring unknowns and timelines accurately contributes to a better evaluation of productivity and trust among team members.Having clear past, present, and future plans helps in reflecting back on productivity accurately.Overall, true productivity stems from a combination of internal and external factors and a continuous effort to improve and adapt.
