L2 · Commercial Architecture Specification

Design the operating model first. Then specify what the technology must build.

An 8–12 week design engagement. We run decision workshops with your commercial team. We lock the operating model block by block — every decision evidenced, every option discounted with reasons recorded. The output is a build-ready specification your implementation partner can quote against, not interpret from.

What L2 produces

Five deliverables. Decisions evidenced. Build-ready.

L2 produces concrete artefacts your implementation partner is bound to deliver against. Each one carries the decision audit trail — the evidenced recommendation, the workshop outcome, the options discounted, and the rationale behind every choice.

Workstream Specification Packs

One pack per major design area. Each contains the design principles, the operating model, every decision made, and the build requirements your partner is bound to.

Target Operating Model

How the business will run after the platform goes live. Customer processes, decision rights, exception handling, governance. Specified before configuration starts.

Build Specification

Entity model, fields, triggers, SLAs. The technical artefact your partner configures against, with owner named per row — including where third-party tools sit.

Target Technology Architecture

The system map. Where data lives, how it moves, which platform owns the truth. Integration boundaries fixed before any code is written.

90-Day Calibration Plan

The post-launch window for refining values, cadences, and edge cases the design surfaces in operation. Change control agreed before go-live, not invented after.

L2 requires a completed L1 audit.

L2 builds on the inputs L1 surfaces. We don’t skip the audit to begin specification directly — the design brief from L1 sets the scope and the priorities. If you have an audit produced by another party, we’ll review it as part of L2 scoping. See the L1 audit →

How L2 works

Five steps. Decisions made in sequence, never skipped.

Each step produces the input the next runs against. The decisions are workshop-driven and audited. The build team gets a specification — not a vision.

Inception

Workstream scoping with the sponsor. L1 outputs synthesised. Peer benchmarks gathered. Operational owners named per block.

Evidenced Recommendation

Three sources drawn together: what your commercial team said in L1, best practice from parallel organisations, and the architectural direction toward streamlined operations and customer-centred experience. The starting point per block — evidenced, but not the answer.

Decision workshops

Your commercial team works through each block. Options discounted with reasons recorded. The room often goes broader than the recommendation — that is the value.

80% readout

Corrected recommendation with the room’s decisions. Final refinement window before specification lock. Every decision evidenced and reversible through change control.

Build spec & handover

Decisions translated into entity model, triggers, SLAs. The specification handed to your implementation partner with the decision audit trail intact.

What L2 typically covers

Workstreams. Designed in parallel, integrated by design.

Most L2 engagements run four to five workstreams. The exact mix depends on the L1 audit. Each workstream produces its own specification pack. The governance workstream is the integrating layer that keeps the others aligned through delivery.

Workstream 01

Customer Acquisition

The lead-to-customer journey. Channel routing, qualification, deal desk authority, pricing exposure. The architecture of conversion in your specific model.

Workstream 02

Onboarding & First Value

The first 90 days after acquisition. Setup, activation, the first-value moment, relationship manager intro. The window where retention is decided.

Workstream 03

Lifecycle Engagement

Day-to-day servicing, self-service usage, lifecycle communications. The interactions that drive renewal or attrition over time.

Workstream 04

Renewal & Retention

The renewal window. Value evidence, risk signals, the conversation guide. Turning renewal from a cold ask to a confirmed decision.

Workstream 05 · Integrating

Governance Architecture

Decision rights, change control, KPIs, calibration plan. The layer that keeps the other four aligned as the build proceeds.

Engagement timeline

Eight to twelve weeks. Four design phases.

Timing scales with the number of workstreams. The sequence is fixed: scoping before drafting, drafting before workshops, workshops before lock. We do not parallelise the architecture — that is where most programmes fail.

The investment, in commercial terms

What L2 prevents. What L2 costs. What it costs in-house.

A specified operating model is the difference between a programme that delivers the business case and one that defends scope creep. Three numbers worth knowing.

What L2 prevents

15–30%

Typical rework cost without specification

On platform programmes that proceed without a specified operating model. Configured processes torn out and rebuilt because the upstream gap surfaces too late.

What L2 costs

3–6%

Of the implementation budget it protects

L2 typically costs a small fraction of the platform spend it de-risks. It isn’t a standalone purchase — it’s insurance on the delivery already approved.

What it costs in-house

£30K/mo

Senior FTE, fully loaded with pension & benefits

Twelve weeks comes to £90K — the same as L2 at its upper bound. The FTE arrives without frameworks, without bluechip transformation track record. And the salary continues long after the project should have ended.

Investment

£45K–£90K. Scoped to the workstream mix.

L2 investment scales with the number of workstreams, the complexity of each, and the integration depth. We confirm the figure during scoping against the L1 design brief — never as an open range carried into the engagement.

Worth knowing: every L2 engagement includes the 90-day calibration plan and the full decision audit trail. Both protect against drift after the build begins.

The Principle

Architecture Before Technology.

Design how the business will operate. Then specify what the platform must build to support it.
