The SAP Reference Business Architecture (RBA) framework assists in understanding the structure and linkage between business capability and process models, and between business and solution architecture. Also, it delivers guidance in the organization and management of enterprise and business domains, end-to-end processes, and solution components.
Key Components of Reference Architecture Content
- Business Architecture and Solution Architecture are focal points
- Business Capability Model and Business Process Model are pivotal elements
Business Capability Model (BCM):
- Organizes business capabilities are essential for achieving strategic objectives
- Adheres to the mutually exclusive and collectively exhaustive MISI principle
Organized by:
- Business Domain
- Business Area
- Business Capability (what the business does to generate value)
Business Process Model (BPM):
- Classifies business processes into eight end-to-end groups
- Linked to the APQC framework, especially the Process Classification Framework (PCF)
- Connects to BCM via business activities
Solution Architecture
- Depicts solution components, their roles, business functions they provide, and the data objects they manage
- Solution Capability Model and Solution Process Model are the main aspects
- The product map details all solution capabilities and components for implementing business capabilities
Linkage Between Business and Solution Architecture
- Business Capabilities are tied to various solution capabilities and components
- Both architectures are anchored by four Enterprise Domains:
- Develop Product and Service
- Supply (Fulfill Demand)
- Customer (Generate Demand)
- Corporate (Plan and Manage Enterprise)
Entity and Object Relations
BCM
- Describes what the organization must deliver
- One-to-one ownership assignment to business areas and domains
BPM
- Defines how the organization delivers business value via structured processes
- Business activities linked to APQC’s Process Classification Framework (PCF)
Model Integration
- Solution capabilities and components aligned with business capabilities to support processes and activities
- Capabilities from BCM can be reused across different BPMs
Industry-Specific Customization
- Flexibility to tailor business capability maps for different industries
- Ability to apply multilayer filtering for organizations spanning multiple industries
The SAP Enterprise Architecture Framework interconnects business capabilities and processes with solution architecture, structured under enterprise domains. Business capabilities map to solution capabilities, fulfilling strategic organizational needs while maintaining consistency and flexibility across various industries and processes.
