From decision to delivery, with clear ownership.

We define the problem to address first. Then we agree what will change, who will implement it and what will count as completed work.

Explore the working phases

New evidence can reopen an earlier decision.

The link between strategy and implementation.

At Hornpiper, GTM Engineering is the discipline of putting go-to-market and revenue decisions into practice through data, workflows and technology. Strategy, implementation and operations share a commercial objective.

Our method is not a universal prescription. We separate observation from interpretation and assess the priority constraint hypothesis alongside alternative explanations. New evidence can reopen a decision.

Diagnose

Which problem should we address first?

We examine the commercial objective, customer journey and available data together. We define a problem that can be investigated without treating a symptom as a proven cause.

Team interviews and a review of current workflows
Assessment of data coverage, gaps and alternative explanations

Deliverable: A priority problem, constraint hypothesis, information gaps and an initial measurement.
Your team’s role: Clarify the objective, provide relevant data access and involve the process owners.

Decision point: Agree on the problem definition and what evidence could change the assessment.

Design

What will change, and how will we judge it?

We connect offer, content, channel, process and technology decisions to the priority problem. Each proposal has an owner, dependencies and evaluation criteria.

Design of workflows and necessary data definitions
Definition of scope, measurement plan and implementation sequence

Deliverable: An implementation plan, ownership map and acceptance criteria.
Your team’s role: Make commercial decisions and confirm team capacity, budget and dependencies.

Decision point: Approve scope and exclusions before implementation starts.

Build

Does the proposed work function in practice?

We implement agreed content, campaign, measurement or system changes. Deliverables are tested against use cases, with failure handling and team handover considered together.

Implementation of scoped content, channels, CRM or integrations
Acceptance tests, access checks and team guidance

Deliverable: Tested deliverables, an open-issues list and usage documentation.
Your team’s role: Evaluate deliverables against real working scenarios and decide on go-live.

Decision point: Check acceptance criteria and record open risks and the go-live owner.

Operate

What did we learn, and what should change next?

We review system use and commercial signals. Data quality is checked before outcomes are interpreted in context. Where needed, we revisit the problem definition or design.

Performance and error reviews at the agreed cadence
Planning of experiments, improvements and next priorities

Deliverable: A decision record, improvement backlog and next review plan.
Your team’s role: Maintain operational ownership, share changes on the ground and decide priorities.

Decision point: Record the decision to continue, change or stop alongside the evidence and measurement limits.

What do we agree before starting?

You do not need to buy all four phases from scratch. If a design or implementation already exists, we assess its suitability first. Ongoing operational support is scoped separately.

A shared objective and decision owner

We establish the commercial question and who makes the decision when priorities change.

Deliverables and acceptance criteria

We define what counts as completed work. Technical acceptance and evaluation of commercial outcomes are separate considerations.

Handover and operating ownership

Documentation, access, maintenance and follow-up responsibilities are part of delivery. Indefinite support is not assumed.

Common questions

Does every engagement include all four phases?

No. Existing work is assessed first, and the engagement starts where support is needed. Phase depth, implementation ownership and ongoing support are agreed separately.

How does the internal team participate?

Decision owners join diagnosis, validate design and take explicit roles in the operating model.
