Delivery economics
Maximize disagreement while disagreement is cheap
RDD is not a pitch for bargain software. It is a way to move expensive misunderstandings into a cheaper room before production work compounds them.
Late misunderstanding is expensive
A misunderstood workflow can be corrected quickly inside a disposable working model. The same misunderstanding discovered after detailed design, architecture, implementation, test automation, integration, acceptance, and deployment may become a delivery, operational, or contractual problem.
RDD treats disagreement as progress when it appears early. "That is not how we work" is a valuable sentence if it arrives while the team is still shaping the workflow.
The value is risk reduction
The commercial promise should be framed as shorter time-to-clarity, stronger scope confidence, better estimates, fewer late surprises, and less avoidable rework. Those effects can improve budget outcomes, but they are not the same as selling production engineering at prototype speed.
Build to Learn may be fast and flexible. Build to Deliver remains production-grade engineering.
- Disposable candidateMinutes or hours to revise.
- Design and architectureCorrections affect structure and planning.
- Implementation and integrationCorrections multiply across code, data, tests, and dependencies.
- UAT and productionCorrections become delivery, operational, or contractual problems.
What should change
The signal is lower post-baseline behavioral scope churn, fewer UAT expectation gaps, more discarded functionality before production engineering, fewer workflow surprises during Build to Deliver, less rework caused by misunderstood behavior, and more production scope backed by accepted evidence.
The point is not to believe the method. The point is to test whether moving working experience earlier reduces the rework and ambiguity that used to land inside delivery.
