A global medical technology manufacturer sought to align its IT landscape modernisation toward SAP BTP and a hybrid-cloud architecture — but the existing EA big-picture was incomplete, the ADOIT system architecture was not populated, and EA guardrails existed only on paper. Portamus operationalised the big-picture across the three core domains of core operations, procurement, and sales, fully integrated it into ADOIT, designed the integration architecture for SAP BTP, and introduced binding EA guardrails and a structured governance process — all within ten months.

Global Medical Technology Manufacturer Modernises Enterprise Architecture with SAP BTP
TOGAF big-picture operationalisation, ADOIT integration, and EA governance for three core domains — including hybrid-cloud integration architecture with SAP BTP.
The Engagement at a Glance
Where the Organization Stood
A global medical technology manufacturer held an incomplete EA big-picture, had no clear cloud transition paths for its SAP BTP migration, and lacked binding EA guardrails — making EA governance effectively inoperative.
Incomplete Big-Picture
The existing big-picture of the IT landscape was incomplete and not reflected in the ADOIT as-is system architecture — a reliable basis for architecture decisions was missing.
Unclear Cloud Transition Paths
The transition to SAP BTP and a hybrid-cloud environment was strategically desired but architecturally undefined — risks and dependencies were not transparent.
Missing EA Guardrails
EA principles and guardrails/guidelines existed only in draft form — solution architects worked without binding architectural constraints.
What We Did
Big-Picture Operationalisation and ADOIT Integration
The big-picture was completed and integrated into ADOIT, then finalised and adopted across the three core domains: core operations, procurement, and sales.
Hybrid-Cloud Integration Architecture
Portamus designed the integration architecture for the SAP BTP deployment and specifically addressed the challenges of hybrid-cloud environments.
EA Governance and Guardrails
EA principles were finalised, guardrails/guidelines renewed, and a structured EA governance process rolled out — solution architects now receive as-is and target architectures as decision input.
What Changed
Core Domains Covered
The big-picture was finalised and adopted across the three core domains: core operations, procurement, and sales.
Hybrid-Cloud Integrated
The integration architecture for SAP BTP was designed with explicit treatment of hybrid-cloud dependencies.
EA Tool Fully Populated
The ADOIT as-is system architecture was merged with the big-picture — the EA is now model-based and tool-supported.
Project Duration
EA governance was fully operationalised and guardrails rolled out organisation-wide within ten months.
What Made This Engagement Work
Big-Picture First
Without a complete and organisationally accepted big-picture, EA governance is not possible — investment in a solid as-is picture pays dividends in every subsequent decision.
Hybrid Cloud Requires Explicit Architecture
SAP BTP and hybrid-cloud setups create new integration complexity that leads to unmanageable dependencies without an explicit integration architecture.
Guardrails Over Case-by-Case Reviews
EA guardrails and guidelines enable solution architects to make good decisions independently — this scales better than a centralised review bottleneck.
