Nobody actually does it. The only difference is that we did. Josef runs product and technology at Mews, the hospitality cloud platform for hotels. This year he stopped debating the product builder model and moved his whole department onto it. Today R&D has three roles: builders who own a problem from discovery to production, a small bench of specialists for the hardest problems, and the managers of builders. Every builder owns a metric. - **3**roles left in all of R&D - **200+**product builders - **0**engineering managers MS Your host **Matej Stefanik**CPO, ClosedLoop AI Asks the questions, then hands over to you. The story ## Four chapters. The details are for the live session. - 01 **The doubt** Big tech shipped faster with AI. Nobody could show more outcomes. - 02 **The test** Engineers got unlimited AI. The bottleneck moved somewhere unexpected. - 03 **The switch** One day, everyone in R&D started a new role. - 04 **The aftermath** Who loved it, who did not, and what it did to the org. What we will get into ## The questions product leaders keep asking about this model. Matej asks them, Josef answers with what actually happened at Mews. Then the floor is yours. - Speed vs outcomes ### AI made engineering faster. Why did that not turn into more outcomes, and what did? - The role ### What does a product builder own end to end, and where do specialists still matter? - Discovery - Design - Build - Ship - Measure - The operating model ### How do you run R&D when every builder owns a metric and every review is about moving it? - The people side ### How did the organization take it, and what changed for the people who used to manage? - Your first step ### What would Josef do differently, and where should your team start?
