The traditional, linear handoff from product (PRDs) to design to dev is too slow for AI's rapid iteration cycles. Leading companies merge these roles into smaller, senior teams where design and product deliver functional prototypes directly to engineering, collapsing the feedback loop and accelerating development.

The historical separation between product management, design, and engineering is dissolving. AI assistants handle the coding, allowing a single person to define the product (PM), ensure high-quality aesthetics and UX (designer), and direct the technical implementation (engineer), thus converging the three roles.

The traditional workflow (Idea -> PRD -> Alignment) is outdated. Now, PMs first create a functional AI prototype. This visual, interactive artifact is then brought to engineers and scientists for debate, accelerating alignment and making the development process more creative and collaborative from the start.

Dylan Field predicts that AI tools will blur the lines between design, engineering, and product management. Instead of siloed functions, teams will consist of 'product builders' who can contribute across domains but maintain a deep craft in one area. Design becomes even more critical in this new world.

In an AI-driven world, product teams should operate like a busy shipyard: seemingly chaotic but underpinned by high skill and careful communication. This cross-functional pod (PM, Eng, Design, Research, Data, Marketing) collaborates constantly, breaking down traditional processes like standups.

The traditional, linear handoff from product spec to design to code is collapsing. Roles and stages are blurring, with interactive prototypes replacing static documents and the design file itself becoming the central place for the entire team to align and collaborate.

The common product development process is a sequential handoff model. A better approach is a "jazz band" model where cross-functional teams collaborate harmoniously from the start. This fosters creativity and reduces rework by including engineers in early ideation, rather than treating them as a final step.

Figma's data shows nearly two-thirds of its users identify with two or more roles (e.g., design, product, engineering). This suggests a shift away from rigid professional lanes. People increasingly see themselves as generalist "product builders," requiring tools that facilitate cross-functional collaboration rather than catering to a single title.

The best products are built when engineering, product, and design have overlapping responsibilities. This intentional blurring of roles and 'stepping on each other's toes in a good way' fosters holistic product thinking and avoids the fragmented execution common in siloed organizations.
