An empirical evaluation

The first is the planning process or how planning is accomplished. The second is planning evolution or howplanning evolves as a learning system. Both perspectives can provide practical guidance on how organizations will change theirplanning process over time in an attempt to improve their effectiveness as well as leverage their investment in SISP. This paperdraws on prior literature to identify key dimensions of SISP and its effectiveness. The evolution of these dimensions is studied asa three-stage model. The results provide an interesting insight into how planning evolves as organizations reconcile seeminglycontradictory ‘‘rational’’ and ‘‘adaptive’’ dimensions of planning. This balanced approach to planning is shown to be moreeffective, providing strong implications for both research and practice.# 2004 Elsevier B.V.
