I was standing at the front of a meeting room, laptop plugged into the presentation screen, walking a group through a prototype built with our prototyping framework.

โBefore we dive inโฆ just to confirm, this is ๐ข๐ง๐ต๐ฆ๐ณ youโve gathered all the use cases, written the specs, handed them to the team, and theyโve coded it all up?โ
๐จ๐ฝโ๐ป ๐ ๐ฒ:
โNot quite. There are no specs. No coded screens. Iโve simply modelled the problem space.โ
๐ฉโ๐ผ ๐๐๐๐ถ๐ป๐ฒ๐๐ ๐๐ป๐ฎ๐น๐๐๐:
โButโฆ you havenโt even written the stories yet? Where are the requirements for Create, Edit, Delete? Whereโs the document for how Staff link to Photo Shoots?โ
๐จ๐ฝโ๐ป ๐ ๐ฒ:
โThatโs the point. Our approach doesnโt need them. ๐ช๐ฎ๐๐ฐ๐ต.โ

โHold on. You havenโt built any of these screens?โ
๐จ๐ฝโ๐ป ๐ ๐ฒ:
โNo. These are generated from the model. The entity definitions, the relationships โ thatโs all it needs to give you full Create, Read, Update, Delete, search, relationship management, and even validation.โ
๐ฉโ๐ผ ๐๐๐๐ถ๐ป๐ฒ๐๐ ๐๐ป๐ฎ๐น๐๐๐:
โSoโฆ we donโt need to write those use cases?โ
๐จ๐ฝโ๐ป ๐ ๐ฒ:
โNo, unless you need to document the obvious ๐. Your time is better spent capturing the rules that make this business unique:
What happens when a Staff member is on holiday, or sick?
What workflow triggers when a Drone is damaged during a shoot?
Thatโs the valuable work.โ
๐จโ๐ผ ๐ฃ๐ฟ๐ผ๐ท๐ฒ๐ฐ๐ ๐ ๐ฎ๐ป๐ฎ๐ด๐ฒ๐ฟ:
โAnd youโre saying this is ready for stakeholders to explore ๐ณ๐ช๐จ๐ฉ๐ต ๐ฏ๐ฐ๐ธ, without waiting for a Sprint cycle?โ
๐จ๐ฝโ๐ป ๐ ๐ฒ:
โExactly. You can click, create, edit, and test relationships live. And if the requirements change, we adjust the model and the prototype updates immediately.โ

โIโve never seen anything like that. Weโre looking at an interactive demo of the domain – without weeks of specifications and development.โ
๐จ๐ฝโ๐ป ๐ ๐ฒ:
โThatโs the power of a ๐๐ถ๐๐๐ฎ๐น ๐บ๐ผ๐ฑ๐ฒ๐นโ๐ณ๐ถ๐ฟ๐๐ approach. The plumbing is done for you. Youโre free to focus on the problems that genuinely deliver value.โ
