The document discusses the need for innovation in enterprise IT outsourcing, highlighting issues related to siloed IT systems and their inability to adapt effectively to transformational needs in the face of globalization and technological advancements. It emphasizes the necessity for a model-driven approach to create a holistic understanding of enterprise requirements, improve interoperability, and foster data-driven decision-making. Solutions proposed include optimizing the design of operational processes, addressing non-interoperability, and developing modular IT architectures that cater to diverse enterprise needs.

50. IT Plant Architecture
• What
– Arrive at an architecture for IT plant catering to varying needs of customers in
same domain
• Why
– Large enterprises needs plethora of applications to meet their needs.
– Needs of no two customers in same domain are exactly identical
– Various situations Service Providers need to service customer are
• Deliver as-is solutions
• Manage known , unknown configurations
• Manage known , unknown extensions
• Deliver parts and integrate existing systems
– Problems
• Not designed to manage these scenarios
• follow clone-n-own approach
• Increased ADM cost
• Customer not sure of certainty of meeting their needs

51. IT Plant Architecture
• How
– Modularity of IT plant
• Investigate mechanism, techniques for modular design for
– System of system scenario
– Multi-layer architecture
– Capturing Commonality and Variability
– Design time and Runtime variability
– Integration
• Investigate automation for COTS integration
• Evaluation of COTS for quality attributes
– Performance
– Reliability
– Configurabity
– Evaluation of NFR
