Expand reach to collaborative processes which are often paper or Excel-based and preceding or parallel to processes covered in back-end systems.

Business need
• Many users work based on paper, Excel, or mail
• Volatile processes which are not tracked (not measurable)
• Processes inside current systems are not flexible enough
• Implement new processes without upgrading the existing ones

Approach
• Build Packaged Composite Applications covering
• Use SOA for integrating with back-ends
• Use modeling to offer the flexibility needed

Summary
1. Composite Applications empower companies to drive innovative business processes leveraging existing IT investments.

2. Composite Application Frameworks (like SAP CAF) provide a methodology and toolset to efficiently develop and manage composite applications—following SOA principles.

3. Metadata-based modelling tools help developers to abstract from technologies, frameworks, and programming languages and at the same time improve flexibility, productivity, and quality.
