Leveraging shearing layers model for providing of agility of enterprise information system
Keywords:
enterprise information system, information systems development and support, shearing layers modelAbstract
Issue of providing of agility of enterprise information system (IS) which is defined as an ability to detect changes in external environment (for example changes of functional requirements) and effectively react to these changes is discussed. System’s splitting to relative weakly bound modules which can develop independently is considered as a main manner to provide agility. Enterprise IS is considered as a combination of few layers that exist in different time scales and relationships between them are minimal. Variants of such splitting are discussed, it is shown how this approach complements the more traditional views on IS which is based on enterprise architecture in the design of agile systems.References
