Outline Mintzberg again Galliers & Leidner Early assumptions about IT strategy Assumptions change… Peppard et al (2014) Ad hoc IS planning SISP Building an IS capability IS Strategizing
Remember Mintzberg’s view of Strategy? Source:H. Mintzberg and J. A. Waters, “Of Strategies, Deliberate and Emergent,”Strategic Management Journal 6 (1985), pp. 257-72.
Galliers & Leidner: Strategic Information Management • IT management must not only be sensitive to the phase of a technology, but also its impact on the organization • As technology, environment and organization change, so too must the priorities which organizations give to their IS portfolios. • The strategic impact of IS/IT on an organization will vary over time
The early assumptions on IT strategy The strategic alignment model (Henderson & Venkatraman, 1993) Assumes that linkages/alignments between key components must be in place
Assumptions change over time… 1980s 2000s 1950s
Ad hoc bottom-up approach to determining IS • Praxis: Ad hoc approach to determining EDP and computing requirements • Practitioners: IT staffs • Practices: Most emphasis on building systems rather than determining strategy. Illustrative tools: Systems development methodologies • Description: Ad hoc, bottom up, primarily driven by technology requirements. IS plan operational in focus, for the most part identifying individual applications (cf Galliers and Sutherland, 1991)
IS planning • Praxis: Top down approach to determining IS needs to meet business goals. Shared group understanding of a few key individuals (Ciborra, 1994) • Practitioners: IT staffs • Practices: Planning based on an informal network of a few key individuals (Pyburn, 1983; Earl, 1993)Illustrative tools: IBM Business Systems Planning Andersen Consulting Method 1 Critical success factors (Rockart, 1979) • Description: Formal top down planning for IS. IS plans reactive to business plans. Aligning to business goals (Kriebel, 1968; Zani, 1970; McFarlan, 1971; King and Cleland, 1975; Zachman, 1978; King, 1978)
Strategic planning for information systems • Praxis: Team approach (Mentzas, 1997). Involving multiple stakeholders (Earl, 1993). Importance of feedback in assessing IS planning effectiveness (Baker, 1995) • Practitioners: IS strategy promoted as a business management issue (Earl, 1989). Senior management and IT staffs • Practices: Focus on themes (Earl, 1993). IS plans periodically reviewed to adapt to changing circumstances (Earl, 1993). Illustrative tools: Customer resource lifecycle, Strategic thrust analysis, Five forces analysis, etc • Description: Proactively seeking opportunities for competitive advantage from IT (McFarlan, 1984; Porter and Millar, 1985; Earl, 1989)
Building an IS capability • Praxis: IS capability embedded in fabric of the organization • Practitioners: All employees • Practices: Influenced by organizational culture; and information orientation of organization (Marchand et al., 2000) • Description: Acknowledging that having a strategy is only part of what is required. Ability to continually identify opportunities, deploy technology, implement change and use information and IT (Peppard and Ward, 2004)
IS strategizing • Praxis: Cognitive and intellectual dimensions. ‘‘The most important direct predictor of alignment in this study was a high level of communication between IT and business executives’’ (Reich and Benbasat, 2000) • Practitioners: All employees • Practices: Co-evolution of business and IT strategies (Benbya and McKelvey, 2006; Breu and Peppard, 2003) • Description: IS strategy something that organizations do rather than have. Integrating IS considerations into the discourse on business and knowledge strategy (Galliers, 2011). Functional strategies having a digital component; fusion of IS and business strategies – the digital strategy (Bharadwaj et al., 2013)
Summary IT strategy has become a key concern for today’s organizations The role and meaning of IT strategy depends heavily on the role and meaning of the character of IT There are several distinct approaches to IT strategy – a firm must make informed decisions regarding what approach to pick
