15 IM AR Definition: Situational Applications Situational application development involves aggregating, customizing, or extending an existing collection of simple web services –Built to solve an immediate, specific business problem –Typically performed by non-traditional programmers (e.g., business professionals, analysts, other IT staff, etc.) –Makes use of pre-existing software components or services such as spreadsheets, report generators or vertical business applications already in use –Manipulates static and increasingly dynamic content – information-centric –Accelerated by a community-based development approach Integration is pushed to the edges and on a global scale

16 IM AR The Accelerating Evolution of Software New tools and approaches to develop situational applications – applications built with simplicity, efficiency, and just enough function to solve the business problem at hand – are emerging –Proliferation of easy-to-use software, tools and techniques (e.g., Web 2.0, LAMP, PHP) –Wide availability of domain-specific web services (e.g., Google maps, UPS, NoAA) –Simple application paradigms to manipulate, integrate, and publish dynamic content (e.g., QEDWiki) –The rapid growth in computer literacy and non-traditional programmers These trends will result in significant challenges for enterprise IT environments –Supporting and enabling community-based development within the enterprise –Refactoring interfaces to enterprise applications as consumable web services –Dealing with the growing heterogeneity in the IT environment –Facilitating the development, deployment, and management of situational applications Situational application development approaches will fundamentally change the way applications are developed and deployed, accelerating the proliferation of consumable web services Situational application development paradigms are emerging which will challenge traditional IT development
