Instead of being limited by off-the-shelf software, designers can dramatically accelerate their process by building bespoke tools. MDS used the AI tool V0 to create a custom bitmap icon builder, enabling rapid prototyping of a unique interactive element.

Bootstrapped to over $100M in revenue, SendCutSend provides custom-machined parts. Its advantage isn't just cost, but speed and a simple software interface for engineers to upload designs—a focus on user experience that traditional manufacturing shops lack.

A product manager's casual comment to an engineer about combining parts led to the engineer building a functional prototype overnight using existing components and a 3D printer. This tangible model quickly gained executive attention and became the basis for a formal project, bypassing typical ideation hurdles.

For early R&D, don't waste time designing custom components in CAD. Instead, buy existing products, tear them apart, and reuse their mechanisms. A simple tape measure can serve as a constant force spring, saving hours or days of design work and getting to a proof-of-concept faster.

Instead of starting with a blank slate, Nike's team prototypes new ideas by physically cutting and modifying existing products. This "cobbling" method enables rapid, low-cost testing of core concepts before investing in new designs and expensive molds, allowing them to fail fast and forward.

Boom Supersonic accelerates development by manufacturing its own parts. This shrinks the iteration cycle for a component like a turbine blade from 6-9 months (via an external supplier) to just 24 hours. This rapid feedback loop liberates engineers from "analysis paralysis" and allows them to move faster.

The default instinct is to solve problems by adding features and complexity. A more effective design process is to envision an ideal, complex solution and then systematically subtract elements, simplify components, and replace custom parts. This leads to more elegant, robust, and manufacturable products.

Leverage Figma's AI not for building entire prototypes, but to accelerate the design process. A PM can take an existing design, use Figma Make to generate variations for edge cases or error states, and then share those layered assets back with the designer, saving significant time.

Building custom components for early-stage prototypes is slow and expensive. A faster, more cost-effective approach is to buy existing commercial products that contain similar components, then scavenge those parts for your prototype. This enables rapid concept validation without investing in custom design and manufacturing.
