- APPROACH

How we engineer AI.

Eight commitments that shape every Prozone AI engagement. They reflect decisions we have already made about what kind of AI work we put our name on - and what serious AI engineering looks like in production.

- COMMITMENTS

Eight engineering commitments.

Decisions we've already made about what serious AI work looks like - so each engagement starts from the methodology, not from scratch.

01

Data first, model second

Quality of an AI system is mostly the quality of its data pipeline. Models change every year; the data and the domain don't. We invest disproportionately in extraction, structure and validation - that's where durable value compounds.

02

Retrieval is engineering

The retrieval layer decides what the model can know. Hybrid lexical-semantic search, multi-stage ranking, learned ranking with domain priors - designed and measured per domain. Off-the-shelf retrieval rarely holds up on serious data.

03

Evaluation is a deliverable

We build the eval harness before the system. Golden sets, regression tests, hallucination measurement - shipped alongside the system and audited continuously. Quality is verifiable, not a matter of trust.

04

Right tool for the task

Fine-tune when behaviour must be internalized. Retrieve when knowledge changes faster than retraining. Prompt when effort is better spent elsewhere. Real systems combine all three, weighted by the domain.

05

Agentic systems with guardrails

Agents that take actions need a strict action surface, an explicit trust boundary, and an eval harness that tests multi-step behaviour - not a chatbot with API access and a prayer.

06

Continuous evaluation in production

The accuracy number at launch is the least interesting one. We design telemetry, drift detection and quality dashboards from day one - so the partner can see whether the system is improving or drifting.

07

Domain-in-the-loop

Subject-matter experts shape the data, the rubric, and the failure modes. AI does not replace the expert - it changes where the expert spends their time. Every system encodes a working partnership with the domain.

08

Privacy & deployment posture

Where the system runs is part of the design. On-prem, private cloud, hybrid, on-device - chosen by where the data can legally live. AI capability that creates a new exfiltration path is AI capability we don't ship.

- ENGINEERING SEQUENCE

How an engagement actually unfolds.

Six phases, sequenced. The shape varies per engagement, but the order rarely does - because each phase determines what the next one can decide.

01

Domain modelling

Co-developed ontology with subject-matter experts before any model is selected.

02

Retrieval architecture

Hybrid retrieval, structured parsing and entity linking designed up front.

03

Reasoning layer

Models selected to fit the reasoning load, not the other way around.

04

Evaluation harness

Built before the system. Golden sets, retrieval metrics, regression tests.

05

Production integration

Auth, audit, monitoring and operational handover, inside existing platforms.

06

Continuous evaluation

Production traffic feeds back into the eval. Quality measured on a recurring cadence.
