From idea to working software: what the full development lifecycle needs to look like

AI coding tools such as GitHub Copilot and Cursor can accelerate individual programming work, but the article argues that successful AI-assisted software development depends equally on the work before and after code generation. It emphasizes validating product intent through human judgment and user research, maintaining strong shared context and codebases, and preventing AI workflows from becoming isolated setups known only to individual engineers. The proposed lifecycle treats discovery, collaboration, traceability, distributed review, cost visibility, and production-like testing as connected stages rather than a linear process. Human ownership and judgment remain central, particularly for maintainability, design quality, and gradually granting agents more autonomy based on demonstrated reliability. Upsun presents its Dispatch platform, used with Upsun Cloud, as a shared workflow layer that logs human and agent actions, exposes costs, applies adjustable approval gates, and creates preview environments so teams can assess whether features work under realistic conditions before release.
