L2 · Commercial Architecture Specification

Design how the business will run first. Then specify what the technology must build.

An 8–12 week design engagement. We run decision workshops with your commercial team and lock the operating model block by block — every decision evidenced, every option discounted with the 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 build against. Each one carries the decision trail — the evidenced recommendation, the workshop outcome, the options discounted, and the reason 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 an 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 use. Change control agreed before go-live, not invented after.

L2 needs a completed L1 audit.

L2 builds on what L1 surfaces. We don’t skip the audit and start specifying — the design brief from L1 sets the scope and the priorities. If you have an audit from 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 one 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

We bring a recommended design into the room before each workshop — built from what your team said in L1 and what works at comparable organisations. Your team then challenges it, improves it, and decides it. The starting point, not the answer.

Decision workshops

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

80% readout

The corrected recommendation, carrying the room’s decisions. A final refinement window before the specification locks. 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 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. The ones below are examples drawn from a customer-lifecycle programme — an L2 specification can cover any commercial transformation domain L1 identifies, not just CRM. Each workstream produces its own specification pack, and 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 authority, pricing exposure — the architecture of conversion in your specific business.

Workstream 02

Onboarding & First Value

The first 90 days after acquisition. Setup, activation, the first-value moment, the 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 into a confirmed decision.

Workstream 05 · integrating

Governance Architecture

Who decides, how changes get approved, and what gets measured. 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 don’t parallelise the architecture — that’s 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 spends its time defending scope creep. Three numbers worth knowing.

What L2 prevents

15–30%

Typical rework cost without a specification

On platform programmes that proceed without a specified operating model. Configured processes get torn out and rebuilt because the 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 you’ve 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. But the FTE arrives without the frameworks and without a blue-chip transformation track record — and the salary continues long after the project should have ended.

Investment

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

L2 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 trail. Both protect against drift once the build begins.

The principle

Architecture before technology.

Build the software around the business, not the business around the software.
