As consultants for the largest enterprises in Slovenia, we found that even though the literature lists plenty of strategic information systems planning (SISP) methods with clear theoretical merits, the enterprises find these methods too abstract and/or too cumbersome to use in practice. To address this issue, we developed a new approach for the measurement of SISP success that attempts to combine key predictors of SISP success from the fields of strategic information systems planning and strategic business planning in a way that would be as practical as possible for everyday use in enterprises. We hope that our method will thus enable enterprises to validly, reliably and with greater ease measure and control the outcome of the SISP process by clearly defining the SISP success predictors that need to be monitored and by identifying the stakeholders responsible for their management.
