A Theory of User Acceptance of IS Project Management Methodologies: Understanding the Influence of Psychological Determinism and Experience

Despite the overwhelming advantages of using an IS project management methodology, organisations are rarely able to motivate their staff to use them: Consequently, this lack of methodology usage by individuals fails to deliver the expected advantages of better quality, control, less time and effort. We analyse the determinants of an individual‘s intention to use IS project management methodology in order to enable organisations to engineer those that meet the needs of actual users and are really used by them. Results from an exploratory field study conducted in a service organisation, are used to construct a conceptual model. Based upon this research model, we posit that: a) value of a methodology, b) workgroup influence, c) self-beliefs, d) organisational characteristics, and e) previous habits influence intention to use a methodology. Additionally, we find that the strength of these relationships depends upon the needs of an individual and the degree of prior experience they have in using similar methodology.
