Strategic Thrusts Wiseman, Rackoff and Ulrich (1985) The Theory of Strategic Thrusts is an approach to linking Strategy and IT pioneered by Wiseman, Rackoff and Ulrich in 1985. While the pace of competition intensified in the 80s and 90s, simultaneously computers and software applications became more powerful and affordable. No wonder the use of information systems as competitive weapon has been accelerating ever since. But how can an organization discover opportunities for Strategic Information Systems (SIS)? Rackoff, Wiseman and Ulrich developed and implemented a six-phase planning process to identify and evaluate SIS and to win top management support in their article "Information Systems For Competitive Advantage: Implementation of a Planning Process" (MIS Quarterly; Dec85, Vol. 9 Issue 4, p285, 10p, 2). Strategic thrusts are major competitive moves (defensive or offensive) made by a firm, directed at one or more strategic targets.
