IBM Software Group | Rational software 5 Geographic distribution of business―the new norm  Near-shore  Internal staffing  Direct ownership  Offshore  Subsidiaries  Joint partnerships  Direct ownership of foreign facilities and hiring of employees  Outsourced  Service providers assume responsibility for life-cycle processes

IBM Software Group | Rational software 6  Executive needs  Risk management  Performance measurement  Development needs  Project and portfolio accountability  Process traceability and visibility  Secure, tamper-resistant environment  Global impact of local regulations  HIPAA, 21CFR11, Sarbanes-Oxley  Basel II, EASHW  Global standards  ISO 900x, Six Sigma  COBIT, COSO, ITIL  CMM/CMMI, SPICE (ISO 15504) Accommodating compliance―the new necessity

IBM Software Group | Rational software 7 Open computing―a new route to collaboration and innovation  Open standards  Improve data sharing by simplifying integration of disparate technologies  Open architecture  Increase collaboration by easily extending business processes  Open source  Promote innovation by leveraging community development Open architecture Open standards Open source Open computing

IBM Software Group | Rational software 8 Modular systems―greater flexibility  Maximize investments―reuse components  Leverage existing assets and investments  Avoid rip and replace  Increase flexibility―interoperable systems  Connect and share business components  Easily distribute business processes  Accelerate initiatives―scalable and agile  Add capacity or functionality quickly  Scale technology based on business demands  Increase business process efficiency―globally Today, service-oriented architecture (SOA) takes business process automation to the next level
