Businesses typically structure their activities with workflows, which are often implemented in a rather static fashion in their IT systems. Now-a-days, system requirements change rapidly as businesses try to maintain their competitive edge, calling for similar agility of the IT systems. To this paper, the authors present StPowla, an approach that marries service oriented architecture, policies and workflows to support the agile execution of business workflows. In StPowla, the business is modeled by workflows, whose tasks are eventually carried out by services.
