[Abstract] Strategic planning of information systems is, perhaps, going to be more problematic in today’s
world of rapid change and uncertainty. SISP is a cornerstone of the information system discipline, and
very little attention has been paid to its success based on the resource-based view of the firm (RBV). This
paper provides a model for IT capability and strategic information system planning success by
considering environmental and organizational factors that may influence this relationship in a contingency
model. A review of existing IT capability and SISP literature is given to identify the opportunities in
building successful SISP. A model is developed by hypothesizing the IT capability, as independent
variables lead to SISP success as a dependent variable in which organizational and environmental
influences are considered as moderating variables. The control variables are firm size, firm structure, and
industry type. The study proposes a model to conceptualize the relationship between IT capabilities and
SISP success and contingency factors moderating that relationship. This paper explains the ways of
exploiting IT capabilities as specialized and integrated knowledge of the firm in IT area to create a more
successful SISP. The researchers believe that the aim to build a model for SISP success based on RBV
theory is important because this new perspective will be helpful for gaining a superior assessment and
better underpinning of the SISP from a knowledge-based perspective.
