Manufacturing & Automotive

SAP S/4HANA migrations are among the most complex IT transformation programmes a manufacturer can undertake. Enterprise architecture contributes by documenting the current system landscape, designing the target architecture, mapping all interface dependencies, and producing the business process documentation that guides configuration decisions. Without a solid EA foundation, S/4HANA programmes routinely encounter scope surprises, integration failures, and delays caused by undiscovered system dependencies. Portamus's SAP ERP certification means we combine EA methodology with practical SAP architecture knowledge.

We start with an architecture assessment of the existing IT and OT landscape, then work with operational and IT stakeholders to define the target Industry 4.0 architecture — typically spanning IIoT platform selection, edge computing design, MES integration patterns, and the data architecture connecting shop floor to enterprise analytics. The output is a phased implementation roadmap that manufacturing operations teams can execute without disrupting production.

Yes. Automotive OEM digitalisation requirements — such as EDI mandates, supplier portals, quality data exchange, and increasingly, product carbon footprint reporting — create complex integration demands for tier suppliers. We design the integration architectures, define data exchange standards, and produce the technical specifications needed to meet OEM requirements without building custom integrations for every customer.

The OT/IT boundary requires careful treatment because the operational constraints on shop floor systems — availability, latency, change management processes — differ fundamentally from enterprise IT. Our architects work with both IT and operational technology stakeholders to design integration layers, define data flow patterns, and establish governance processes that enable data exchange between OT and IT environments without compromising production stability.

A focused EA assessment for a single manufacturing site or business unit typically takes four to six weeks. For multi-site manufacturers or organisations undertaking ERP consolidation across several production facilities, we recommend a phased approach — starting with a scoped landscape assessment before designing the full target architecture — which may take three to four months for the complete engagement.
