The impact of information systems on business flexibility from the managerial perspective: multiple cases of enterprise systems enhancement and ongoing changes

Today, flexibility is widely concemed as the key capability an organisation should possess due to the fast change of business and technology environment (Haeckel 1999; Golden and Powell 2000). Business is fundamentally concerned with and driven by changes. It requires flexibility to quickly respond to new conditions, to absorb sudden shocks and to accommodate diversity and heterogeneity. All of these demands, in turn, feed through to the computer-systems that modem organisations rely upon (CBDi Forum 2001). The attainment of information system flexibility is becoming an essential requirement for the business (Golden and Powell 2000; Behrsin et al 1994). Despite ITAS has been developed to achieve great flexibility and functionality in order to provide more agile and more effective solution for the businesses, it is also Widely subject to criticism for its inflexibility and rigidity (Allen and Boynton 1991; Avison et al 1995; Davenport 2000). This research addresses the IS flexibility issue and studies "how organisations adapt their ISs/ESs to accommodate ongoing business changes" A model of tactical ES adaptation for ongoing business changes has been developed from three organisations' ES post-implementation experience. This model depicts a complicated decision making process for ES adaptation to support ongoing business changes and attain flexibility. It demonstrates the dynamic relationship among emerging business needs, adaptation tactics, adaptation activities, performance and resource measurement, and risk evaluation
