The system will be separated in independent services which are small, software components.

The services are combined, creating an application system that should remain easily adaptable and changeable. The requirement for this is that the development processes and the culture of software development are flexible.

• For every business-critical project
• For solving complex tasks such as modernizing existing systems
• Step-by-step migration of large legacy systems. SOA offers appropriate mechanisms due to the flexibility and power of its individual components
• Interface issues will get under control

• Better understanding and higher transparence of business processes
• Better exchangeability, maintainability and expandability through unification and standardization
• Different technologies (and programming language) can be combined
• Legacy systems can be integrated
• Better structured, documented and to business processes oriented IT services
• Agile changeable flexible business processes (quicker "time to market")
• Quality improvement through better testability and comparability
• Minor change risk
• Medium to long term cost savings
