Evaluating the adoption of strategic information systems planning (SISP) in global organisations

Abstract

In a comprehensive review of literature on the strategic adoption of information systems (IS), various approaches to strategic IS adoption were unable to verify and coordinate different factors for IS investment as a strategic business unit. An assessment of different models in this area through the review of empirical case studies was required to identify the factors that affect IS strategic adoption, because these factors support the evaluation and adoption of both the process and result of IS strategic adoption. Thus, a study to investigate and evaluate the adoption of strategic information systems planning (SISP) within organisations is required in order to identify the factors that affect this type of adoption. The research in this thesis takes into account the adoption process and the factors for the adoption of SISP. There is also a need to understand and evaluate different IS planning techniques within a framework that can support decision-makers through the entire IS strategic adoption process. This framework is a component of the proposed novel model that considers other crucial factors that influence IS strategic evaluation and adoption. Decision-makers may employ such a model and evaluation framework that considers important SISP criteria, such as (a) SISP benefits, (b) SISP requirements and, (c) SISP drivers, as an important reference tool. After presenting the conceptual components of this research, the empirical side expresses the application of a qualitative research approach through a case study strategy to investigate the proposed model of SISP adoption. As a result, two global organisations were investigated, reported, and analysed. Additional factors for the adoption of SISP emerged from these analyses. The proposed conceptual model was modified to present 11 factors that influence the adoption of SISP, including (a) planning team; (b) benefits; (c) requirements; (d) drivers; (e) costs; (f) IS performance measurement; (g) framework for the evaluation of SISP techniques; (h) SISP methods; (i) SISP tools; (j) support; and (k) IS strategy. The primary contribution of this thesis is a comprehensive novel model for the evaluation and adoption of SISP. The model includes two levels of original contribution. Firstly, it accounts for previous studies in SISP and their factors, which supports the conceptual level of this contribution. The researcher incorporated and extended these studies to merge the factors which were recognised in the normative literature. In addition, factors from empirical work have also been combined in the proposed model, thus developing a consistent paradigm for the evaluation and adoption of SISP. Secondly, the concept and process of the proposed model can be applied as an educational guide throughout the IS strategic evaluation and adoption process. Nevertheless, this model contains a proposed framework for the evaluation of IS strategic planning techniques as factors that influence the adoption of SISP. This framework is novel, since it is a part of the proposed model as well as a classification of IS planning techniques, and supports decision-makers’ understanding and evaluation of planning techniques during the adoption of SISP.
