The Knowledge Your Team Has That Nobody's Using

We’ve all been in the meeting where a project is three months into detailed design, and someone from the back of the room finally sees the CAD or the spec and says: “We tried this two years ago. Here is why it failed.”

At that moment, the room goes cold. You realize that the knowledge to avoid a massive mistake was already in the building. It just didn’t have a path into the conversation when the conversation was happening.

In this week’s podcast episode, I’m sharing the results of an experiment that made this “fog” visible in a way I didn’t expect.

I ran three product concepts (a solar service redesign, a medical device, and a field harvester) through two different development approaches. I used identical teams (simulated via AI agents) and the same product briefs.

The results were a stark reminder that features are not the same thing as clarity.

  • The Traditional Approach produced legitimate work: feature lists, risk registers, and specs. Most organizations would have stamped these “Ready for Engineering.”

  • The Structured Approach produced the same features, but with a critical difference: Context.

  • The side-by-side results of the three case studies.

  • The “Three-Question Filter” you can apply to any design input this week.

  • Why “ready enough” is where expensive ambiguity hides.

Throughout this month, I am publishing a breakdown video series on YouTube showing side-by-side outputs from this experiment. If you want to see exactly how structured concept development looks in practice check out the links below.

About “Pierce the Design Fog”

If you found this insight helpful, consider sharing it with a lead engineer or project manager who is currently navigating their own design fog.
