Strategic information systems planning (SISP) is the process of identifying a portfolio of computer-based applications to support an organization’s business plans and to help it realize its business goals (Lederer and Sethi 1988). The extent of SISP success may be associated with more or less comprehensiveness in the planning process and the stability of the environment (Salmela 1996).
