SAP architecture has a direct impact on operating costs. A well-structured, component-based architecture reduces maintenance effort and enables selective updates. beteo recommends regular architecture reviews as part of SAP ALM.
Architecture and Total Cost of Ownership
Many organizations view SAP architecture as a technical concern separate from business operations. In reality, architectural decisions made years or decades ago continue to drive significant operational costs today. Poorly structured landscapes, excessive custom development, and fragmented integration points all translate directly into higher maintenance costs and slower change velocity.
Key Architecture Principles for Cost Efficiency
Minimize the custom code footprint: Every line of custom ABAP code is a liability that must be tested, maintained, and adapted with every SAP upgrade. Regularly reviewing and reducing the custom code footprint through standard functionality adoption delivers lasting cost savings.
Rationalize the system landscape: Many SAP customers operate unnecessarily complex landscapes with too many systems, sandbox environments, and parallel instances. Landscape rationalization reduces license, infrastructure, and administration costs.
Design for change: Architecture should be designed to accommodate change efficiently. This means clean separation between standard and custom layers, consistent use of enhancement frameworks rather than core modifications, and documented integration architecture.
Conclusion: Regular SAP architecture reviews — ideally as a component of a broader ALM program — help organizations identify and eliminate structural cost drivers before they become entrenched. The right architecture is not the most complex one, but the one most efficiently aligned with the organization’s business requirements.
