When Building Gets Cheap, Decisions Matter More, with Ashley Roach
Fast prototyping changes the constraint.
When software, AI tools, and other rapid-prototyping methods make it inexpensive to turn an idea into something testable, the challenge is no longer only Can we build it? The harder questions become:
What should we build?
- Who is it for?
- What evidence do we need?
- When should we stop tweaking and get it in front of people?
- Which decisions are reversible—and which ones will lock in future choices?
In this episode, Ashley Roach and I discuss how speed can help teams explore ideas, but can also create a new version of the build trap: continuing to improve the thing because building feels productive, before confirming that it is valuable to customers.
Ashley shares how he uses AI tools as thought partners, including an example where an AI system challenged him to stop adding functionality and gather more evidence first. We also discuss one-way and two-way doors, innovation inside larger organizations, cross-functional decision-making, and what changes when everyone in a company can become a builder.
Key Takeaways:
- When building becomes cheap and fast, deciding what to build becomes a more important skill.
- Rapid prototyping can create a build trap if teams keep tweaking instead of testing with real people.
- Two-way-door decisions can often be made quickly because they are reversible; one-way-door decisions require deeper deliberation.
- Engineers, product managers, designers, and other specialists may increasingly participate in work outside their traditional roles.
- A simple opportunity brief can help teams examine whether an idea is worth pursuing before investing further.
Your Challenge
Before you build or keep refining your next idea, write down:
- Who is this for?
- What evidence would show that it is valuable?
- Is the next decision reversible?
If the decision is reversible, consider making it and learning from the result. If it is difficult to reverse, slow down long enough to understand what you are locking in.
