Healthcare organizations often face the challenge of integrating diverse and geographically disparate information technology systems to respond to changing requirements and to exploit the capabilities of modern technologies. Hence, systems evolution, through modification and extension of the existing information technology infrastructure, becomes a necessity. This paper takes a process perspective of healthcare delivery within and across organizational boundaries and the presents a disciplined approach for evolving healthcare systems towards a service-oriented architecture using the enterprise system bus middleware technology for resolving integration issues and the business process execution language for supporting collaboration requirements.
