Production Hardening

Pilot to Production — from promising demo to dependable system.

You've proven the idea works. We do the unglamorous 80% — evaluations, guardrails, monitoring, scaling, and cost control — that turns a pilot into a production system with an owner and an SLA.

What's included

Everything a pilot is missing to go live.

Not a rewrite — the evaluation, safety, and operations layer that makes an existing pilot trustworthy at scale.

Evaluation suite wired into CI

Automated tests that score output quality on every change, gating releases before they ship.

02

Guardrails & graceful fallbacks

Input validation, output checks, and degradation paths when the model is unsure.

03

Full observability & tracing

Every request traced: what was asked, retrieved, generated, and why — in your existing stack.

04

Drift & cost monitoring

Alerts when accuracy decays, data shifts, or spend creeps, before users notice.

05

Staged rollout & handover

Canary release, review gates, and runbooks so your team owns it with confidence.

Engineering deep dive

How it's actually hardened.

The evaluation gate and the topology — not a slide about “best practices.”

Case study

Support-Bot Pilot Hardened for Production Scale

Professional services · Mid-size consulting firm

The challenge

A document-summarisation pilot that leadership loved and engineering dreaded: no tests, unknown accuracy, and inference costs that tripled with every new team onboarded.

The approach

We built an evaluation suite from 300 real documents, added guardrails and full tracing, introduced model-tiering to cut cost, and shipped through a staged rollout with human review on low-confidence outputs.

Pilot audit → evaluation harness (300 test cases) → guardrails & tracing → model-tiering → staged canary rollout
64%Inference cost reduction
96.4%Eval pass rate at launch

The difference

The typical approach vs the elhaa approach.

Typical approach
With elhaa
Quality
Judged by demos and anecdotes
Scored by an evaluation suite on every change
Failures
Discovered by users in production
Caught by guardrails and alerts first
Costs
Found on the monthly invoice
Modelled and engineered before scaling
Ownership
Depends on whoever built the pilot
Runbooks and dashboards your team operates
How the engagement runs

Four steps from audit to owned system.

1

Audit the pilot

Assess the existing POC: quality, architecture, risks, and true cost at scale.

2

Define ‘good’

Agree evaluation criteria and thresholds with stakeholders before touching code.

3

Harden

Add evals, guardrails, monitoring, and security controls layer by layer.

4

Release & operate

Staged rollout with review gates, then handover with runbooks and dashboards.

How success is measured

Agreed in week one, on a dashboard by go-live.

Quality

Eval pass rate

Share of test cases passing the agreed thresholds, per release.

Reliability

P95 latency & uptime

Response times and availability at real traffic, not demo traffic.

Economics

Cost per 1K requests

Unit economics tracked against the cost model, with alerts on creep.

Safety

Guardrail catch rate

Bad or low-confidence outputs intercepted before reaching users.

FAQ

Questions about Pilot to Production AI.

Yes — that's common. We audit what exists, keep what's sound, and rebuild only what blocks production readiness.

We build an evaluation suite from real examples of your task, agree pass thresholds with your stakeholders, and gate every release on those scores.

We tell you early. The audit phase is designed to surface deal-breakers in weeks, not months — sometimes the honest answer is a redesign, and occasionally it's 'don't ship this.'

Alongside, always. Your engineers pair with us through the hardening work — that's how the knowledge transfers, and it's why the system doesn't depend on us after handover.

We're pragmatic and vendor-neutral: open standards where possible (such as OpenTelemetry for tracing) and either your existing observability stack or lightweight open-source tooling. The eval harness is plain code in your repository, not a proprietary platform you're tied to.

Sounds like your situation?

A 30-minute call. We'll tell you honestly whether this is the right solution — and what it would take.
