    Modernization Roadmap

    A staged modernization plan that upgrades the stack without halting the business.

    Why it matters

    Big-bang rewrites kill startups. A staged modernization roadmap with target-state architecture, migration sequencing, rollback plans and explicit build-vs-buy decisions is the only safe way to upgrade while you're still shipping.

    Scope covered

    Target-state architecture (3-yr horizon)
    Migration sequencing + parallel-run windows
    Risk register + rollback plan per wave
    Build-vs-buy decisions on top 10 components
    Capacity & dependency planning
    Modernization KPI dashboard
    How we run it

    Senior-led delivery sequence

    A senior-led delivery sequence — not a template dump. Each phase is operated with your team, not handed over as a deck.

    1. 01
      Week 1

      Target-state & ADRs

      Workshop the 3-yr target architecture, lock guiding principles and capture ADRs for the top 10 directional decisions.

    2. 02
      Week 2

      Wave sequencing

      Slice the journey into waves with parallel-run windows, dependencies, capacity and explicit exit criteria per wave.

    3. 03
      Week 3

      Risk & rollback

      Run pre-mortems per wave; build rollback playbooks, failure-recovery runbooks and a live risk register with owners.

      Week 4–5

      Build-vs-buy & board pack

      Decide build / buy / partner on top 10 components with TCO; assemble the board-grade roadmap and secure sign-off.
