Harness Engineering: Building Your Lean, Mean Delivery Machine

Handing a developer a coding agent doesn't double your delivery. I've watched teams get busier, not faster.

What multiplies output is the harness around the model: the codified context, skills, hooks, sub-agents and ways of working, plus a squad built to run it.
One rule makes the whole thing work: if it's not in the repo, the agent doesn't know. And the part I genuinely didn't see coming: codifying the AI forced the humans to align.

I'll open a real harness I run on Google Cloud, delivering with a fraction of the planned team at a throughput that sounds made up until you see the headcount delta. I'll also be honest about the parts that still need tuning every single week.

The weekend pioneer who ships miracles is real.

But how many pioneers does your org have, and can you run an enterprise on pioneers alone?

This talk is how you get from one to many.

Takeaways:
1. The harness is what multiplies output, and the squad is what runs it. "It didn't happen overnight, and it didn't happen by accident."
2. You can't run an enterprise on pioneers. IC → codified harness → SME-led squad is how weekend-hero output scales without losing cadence or quality.
3. The harness can rot. Left uncurated it poisons its own context; the agent doesn't hallucinate, it just gets confused. Owning it is a weekly discipline.


Duration: 30 min (25 + 5 Q&A), scalable to 45. Audience: builders, architects, engineering leads. Deck built; drawn from live production delivery on Google Cloud. Part 1 of a Build / Secure / Scale signature set.
