Why my perspective is different
The Boundary Model emerged from builder-side exposure to the way SAP BTP extensions fail after go-live: not only as local defects, but as broken contracts across identity, tenant, runtime, integration, data, and lifecycle boundaries.
Builder-side SAP BTP background
- Former SAP engineer with builder-side exposure to SAP BTP platform and extension architecture.
- Worked across CAP, XSUAA, AppRouter, Work Zone, multitenancy, integration, and lifecycle-related failure modes.
- Involved in SAP Build Code / Joule-era platform work and AI-assisted extension generation context.
- Experience diagnosing cross-product failures where local correctness did not produce global architectural validity.
Why this matters
Most external reviews see SAP BTP from the outside: projects, components, configuration, and delivery milestones. My perspective was shaped from the builder side: how identity, tenancy, runtime, integration, data, and lifecycle boundaries actually fail after systems go live.
Why I can issue this kind of verdict
This perspective comes from builder-side SAP BTP work, not from implementation delivery alone.
My background includes SAP Build Code and Joule-era platform engineering context, CAP-based extension architecture, identity propagation, multitenancy, Work Zone entry paths, and cross-product integration failure modes.
The Boundary Model is not a generic consulting framework. It emerged from repeatedly seeing SAP BTP extensions fail across runtime, identity, tenant, data, integration, and lifecycle boundaries after local implementation had already appeared correct.
What I claim
- I provide independent architecture judgment.
- I classify boundary and jurisdiction failures.
- I issue fixed-scope written verdicts.
- I do not replace delivery teams.
- I write and publish openly on post-go-live SAP BTP extension failures, data boundaries, identity propagation, integration boundaries, and lifecycle architecture.
What I do not claim
- I am not SAP official support.
- I do not speak for SAP.
- I do not sell implementation staffing.
- I do not claim every BTP issue is architectural.
- I do not replace customer or vendor execution responsibility.
The Boundary Model
The Boundary Model is the public articulation of this perspective: six runtime-visible boundaries used to classify whether an SAP BTP extension is still structurally safe to evolve, and what must be decided before more delivery continues.
