The Second Wave Arrives

Wave two is the legacy estate everyone avoided: mainframe-adjacent systems, vendor-locked SaaS, and single-human workloads.

Recap. Year one delivered a landing zone and a pilot partnership. Year two opens with a migration programme that has consumed the easy workloads — and a wave two list that violates every design assumption in the decisions document.



Outline

  • Hook: The programme board adds three workloads nobody volunteered for in discovery week
  • Context: Greenfield patterns vs. mainframe-adjacent, vendor-locked SaaS, single-human dependencies
  • Tension: Platform is opinionated vs. platform must take this workload or the programme misses target
  • What happened: (draft — expand with fakey.xyz wave-two onboarding)
  • NZ field note: The meeting where platform said “not on the golden path” and programme said “then the target slips”

Sections to Draft

  • Symptoms of wave two (identity models, data gravity, runtime exceptions)
  • The BUILD / ROUTE / DECLINE framework under programme pressure
  • Metric table: wave-one vs. wave-two time-to-environment
  • Steal-this checklist

Part 2 — “Showback Becomes Chargeback Becomes Politics.” Year one costs were centralised and nobody cared. Year two, finance wants attribution — and the first true platform bill lands on a business unit that did not ask for a landing zone.

One Block

List your wave-two workloads before the programme board does — and mark which design assumptions each one breaks.
