https://harishtalks.com/ Harish Duddupudi on platform architecture, AI agents, cloud-native systems, engineering leadership — and the life around all of it. en-ca Mon, 17 Aug 2026 12:00:00 GMT https://harishtalks.com/writing/the-harness-is-the-asset/ https://harishtalks.com/writing/the-harness-is-the-asset/ Mon, 17 Aug 2026 12:00:00 GMT An agent is a composition — persona, rules, skills, tools — and all of it belongs in the repository. Notes on running a whole product development lifecycle as cooperating agents, and on when parallel is the wrong call.

Two launches this February make clear that assumption is inverting — and the hard part is the same one it has always been.

After a decade of bespoke everything, the fleet problems that remain are organisational, not technical.

The thing that actually decides whether a programme ships is whether four organisations can agree on an interface.

Conflating them is how budgets get spent badly.

The technical question — in-vehicle interface or extended vehicle — decides who gets paid.

Together they invalidate assumptions the core was built on — starting with the idea that settlement happens later.

The remaining problems are semantics, workflow and the fact that a shared record is not a shared understanding.

Reconciling continuous delivery with computerised system validation is the defining problem of the decade.

The code generation was never the hard part — the approval gates and the state model were.

Most teams place that bet by accident, along the shape of the org chart that existed the week the project started.

It also cost more than the pattern's advocates admit — here is the ledger, both columns.

It is that I answered the question instead of finding out why it was being asked.

I do not think that is a coincidence, and it is not really a wellness argument. Harish Duddupudi personal leadership
