Speed compounds value only when the underlying decision is correct.
Cost, speed, quality, architecture, and risk should be discussed as connected decisions.
Technical work should improve decision quality, not create unnecessary distance between technology and leadership.
Documentation, maintainability, operating standards, and transfer matter as much as the initial delivery.
Technology matters when it improves a product, workflow, decision, or operating system.
