RAG Evaluation: What We Measure Before Production — Lessons From Delivery

Straight answer: RAG Evaluation: What We Measure Before Production — Lessons From Delivery — a field note from Shriram IT Ventures for engineering and product leads who need decisions, not another framework essay.

Who this is for

Use boring technology where the risk is operational. Save novelty for the one wedge that makes the product worth buying.

Decisions that still look smart in 18 months

Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.

Build checklist we actually use

Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.

Failure modes we keep seeing

Ship a thin vertical slice, measure, then widen. Big-bang rewrites rarely survive the first month of real traffic.

How we measure rollout

Teams that write trade-offs down before coding burn fewer sprints when a stakeholder changes their mind mid-build. We keep ADRs short on purpose.

We update this when delivery patterns change on live client work.
