Engagement Model · Four phases, written gates

A method built to produce defensible decisions, not deliverables nobody reads.

Every engagement passes through the same four phases, and every phase ends with a written deliverable a partner has signed. A client may leave us at any gate holding something of independent value.

Typical stewardshipMulti-year

Engagement Model

Four phases · written deliverables at each gate

Diagnostic

Four to six weeks. A senior partner and two architects map the system, the team, and the constraints, and produce a signed assessment regardless of next steps.

04–06 weeks

Architecture

Target-state design with options analysis, cost projection, and a regulator-facing transition narrative. Reviewed by a second partner before delivery.

08–12 weeks

iii

Execution Oversight

We embed senior architects with the implementation team, your staff or your integrator, and chair the technical steering committee.

06–24 months

Stewardship

Quarterly review of the operating model. We attend the audit committee on request. Often the longest phase, and the one our clients value most.

Deliverables at Each Gate

What you hold when a phase closes

i · Diagnostic

A signed assessment of the system, the team, and the constraints, written to stand on its own whether or not the engagement continues.

Current-state architecture map
Risk & constraint register
Capability & team assessment
Partner-signed findings memo

ii · Architecture

A target-state design and the reasoning behind it, in a form a regulator or board can follow without translation.

Target-state reference design
Options & trade-off analysis
Cost & timeline projection
Regulator-facing transition narrative

iii · Execution Oversight

The artefacts that keep delivery honest: a chaired steering committee and a documented record of every consequential decision.

Steering-committee charter

Cutover & rollback runbooks
Quality & acceptance gates

iv · Stewardship

The standing review that keeps the operating model defensible long after go-live, and an open seat at the audit committee.

Why the Gates Matter

From the partner desk

The most expensive architectural decision is the one made twice. A written gate forces the decision to be made once, deliberately, and to survive the people who made it. G. Avanzato, Founding Partner
