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 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 Alignment) is outdated.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.

Instead of letting designers complete a holistic, end-to-end design, Dylan Field advises stopping them one-third of the way through. The team should then immediately build a prototype of that core component. Using this prototype reveals the 'physics' of the system, providing crucial learnings that will correctly guide the rest of the design.

The traditional, linear design process is obsolete. The new way of working is a fluid, 'start anywhere' model where an idea can begin in code, a document, a canvas, or a Slack thread, with creators bouncing between tools as needed to develop the concept.

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.

AI co-pilots have accelerated engineering velocity to the point where traditional design-led workflows are now the slowest part of product development. In response, some agile teams are flipping the process, having engineers build a functional prototype first and then creating formal Figma designs and UI polish later.

Instead of a linear design-to-engineering handoff, a "helix" model involves specialists (design, motion, code) continuously spinning around each other's work. This non-hierarchical process fosters co-creation and leads to more integrated, higher-quality outcomes.
