The industry has not standardized who owns AI prototyping. Three models are emerging: PM-led (leveraging deep customer knowledge), design-led (leveraging craft and speed), and collaborative (PMs and designers working together in the tool). Organizations should choose the model that best fits their team dynamics.
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.
AI tools are blurring the lines between product, design, and engineering. The future PM will leverage AI to not only spec features but also create mockups and even write and check in code for smaller tasks, owning the entire lifecycle from idea to delivery.
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 Alignment) is outdated.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.
The traditional product management workflow (spec -> engineer build) is obsolete. The modern AI PM uses agentic tools to build, test, and iterate on the initial product, handing a working, validated prototype to engineering for productionalization.
The team no longer relies solely on PRDs and design docs. Product managers are now required to build a functional prototype as a core part of the development cycle, ensuring ideas are validated with a working model early on.
The traditional PM function, which builds sequential, multi-month roadmaps based on customer feedback, is ill-suited for AI. With core capabilities evolving weekly, AI companies must embed research teams directly with customer-facing teams to stay agile, rendering the classic PM role ineffective.
In AI, low prototyping costs and customer uncertainty make the traditional research-first PM model obsolete. The new approach is to build a prototype quickly, show it to customers to discover possibilities, and then iterate based on their reactions, effectively building the solution before the problem is fully defined.
AI coding agents compress product development by turning specs directly into code. This transforms the PM's role from a translator between customers and engineers into a "shaper of intent." The key skill becomes defining a problem so clearly that an agent can execute it, making the spec itself the prototype.
AI prototyping should be viewed as a fundamental skill for modern PMs, not an extra job responsibility. Just like using Figma to communicate design, AI prototyping tools allow PMs to make abstract AI concepts tangible for stakeholders and customers. This accelerates feedback loops and improves alignment on complex product behaviors.
The traditional "assembly line" model of product development (PM -> Design -> Eng) fails with AI. Instead, teams must operate like a "jazz band," where roles are fluid, members "riff" off each other's work, and territorialism is a failure mode. PMs might code and designers might write specs.
