Delivery model

How we actually work.

No process theater. A five-stage delivery model engineered for clarity, accountability and software that holds up at scale.

How we work

A five-stage delivery model. Boring, repeatable, and honest.

  1. 01

    Discovery

    We listen first — to your operations, constraints, customers and the outcome you actually need. Output: a written scope and success metric.

  2. 02

    Solution Design

    A senior architect produces a system design, integration map, security model and delivery plan you can defend to your board.

  3. 03

    Development

    Engineering in small, observable increments. You see working software every week, not waterfall theater.

  4. 04

    Deployment

    Hardened release, environment cutover, observability and a runbook your team can operate.

  5. 05

    Support & Optimization

    Ongoing partnership — SLAs, evolution, AI-driven improvements and a roadmap that compounds.

Methodology

Discover · Design · Build · Validate · Operate

Every Vestval engagement runs the same five phases — sized to the work. The phases are observable, named, and reviewable. Nothing is implied; everything is on the schedule.

  1. Phase 01

    Discover

    Stakeholder interviews, system audit, constraints, success criteria. Output: a decision-grade brief — not a slide deck.

    • · Discovery brief
    • · System & data audit
    • · Risk register
    • · Success metrics draft

  2. Phase 02

    Design

    Architecture, data model, UX, integration map and rollout plan. Trade-offs are explicit and signed off before code.

    • · Architecture doc
    • · UX flows
    • · Data model + contracts
    • · Rollout plan

  3. Phase 03

    Build

    Senior engineering with weekly demos. Trunk-based, observable from day one, instrumented to be debuggable in production.

    • · Working software weekly
    • · Test + observability harness
    • · CI/CD pipelines
    • · Operational runbooks

  4. Phase 04

    Validate

    Real users, real data, real conditions. Acceptance against the success metrics — not vibes. Security and AI eval gates apply here.

    • · UAT + load tests
    • · Security review
    • · AI evaluation pass
    • · Go/no-go decision

  5. Phase 05

    Operate

    Production support with named senior owners, SLOs, incident response and a roadmap of compounding improvements.

    • · SLA + on-call
    • · Quarterly reviews
    • · Cost & performance reports
    • · Roadmap of compounding work

Operating principles

Senior by default

Every engagement is led and staffed by senior engineers. No bait-and-switch staffing.

Observed weekly

You see working software, dashboards and decisions every week — not waterfall theater.

Written commitments

Scope, success metrics and SLAs are written down. We hold ourselves to them publicly.

Long horizons

We work with clients we can serve for years. Engagements are designed to compound.

FAQ

Engagement FAQs

  • Both. Fixed-scope for well-defined products; T&M for platform and AI work where discovery is ongoing.
