Reengineering business information systems to support business continuity
by Nijaz Bajgoric
International Journal of Business Continuity and Risk Management (IJBCRM), Vol. 8, No. 1, 2018

Abstract: The paper aims at presenting an implementation framework for reengineering traditional business information systems (ISs) into ISs that support business continuity (BC) or 'always-on' ISs. The framework has been developed by using a methodology framework based on a literature review and Churchman's (1971) systemic model, particularly his definition of 'system designer'. Four reengineering drivers are identified: downtime costs, IT-oriented business models, business continuity and IS-systemic perspective. Technology enablers for implementation of such systems are presented as well. Presented framework brings some additional dimensions with regard to modern ISs particularly those related to human aspects (Churchman's client, designer and decision maker). It explores critical aspects of modern ISs such as high availability (HA) ratios, continuous data access, always-on computing, continuous computing technologies, as well as managerial aspects with regard to the roles of CIOs, system admins and business continuity managers. As such, the presented framework can be used in the projects of transforming traditional business ISs into always-on ISs.
