The theories of social exchange, task-technology fit, and technology acceptance are utilized in a field study of software development methodologies. This investigation includes the effects of user experiences on perceptions of acceptance and usage of a methodology. More specifically, perceptions of the outputs and deliverables from a methodology and perceptions of challenges and obstacles to using and applying a methodology were found to significantly and positively influence perceived usefulness and negatively influence ease of use of a methodology, respectively, within a developer's organization. Perceived usefulness was a positive and strong antecedent to perceptions of fit between the methodology and client problems, and the strengthening of efficacy beliefs about the methodology.

This paper evaluates the dynamic aspects of the UML in the context of interorganizational workflows. Two evaluation methodologies are used. The first one is ontological and is based on the BWW (Bunge-Wand-Weber) models. The second validation is based on prototyping and consists of the development of a workflow management system in the aerospace industry. Both convergent and divergent results are found from the two validations. Possible enhancements to the UML formalism are suggested from the convergent results. On the other hand, the divergent results suggest the need for a contextual specification in the BWW models.

This paper describes how three organizations adopted information system (IS) process innovations (ISPI) using a sample of over 200 adoptions over a period of four decades. Four distinct periods that roughly follow Friedman's and Cornford's categorization of IS development eras are analysed in terms of the rate and distribution of ISM adoptions. These eras include early computing (1954-1965), mainframe (1965-1983), office computing (1983-1991), and distributed applications (1991-1997). We distinguish the following four types of ISPIs: base line technologies (T);tools (TO);description methods (D);and managerial innovations (M). We analyse for each era the rate of adopting different types of ISPIs, identify who made adoption decisions for those ISPI types and determine whether these ISPIs originated internally or externally. Within the three organizations, the types and rates of ISPI adoptions varied significantly. These variations can be attributed to learning mechanisms, the influence of legacy platforms and differences in the boundary spanning activities. With the exception of base line technologies, project managers were the most prominent decision-maker group, suggesting a situated ISPI adoption process. In most ISPI adoptions, internal search and experiments were the main source of innovation. The variation in ISPI adoptions can thus be partly explained by development environments, the types of IS involved and attention bias.
Most studies of DSS failure involve survey research, based on factor models. This paper takes an alternative approach and reports on the intensive investigation of a single DSS project in a manufacturing company. The ...

This paper identifies factors that affected over 200 information system (IS) process innovation adoption decisions in three organizational environments over a period that spanned four decades. The analysis is based on Rogers's (1995) theory of Diffusion of Innovations (DOI). The results show that several DOI factors strongly affect IS process innovation adoption. These include user need recognition, availability of technological infrastructure, past experience, own trials, autonomous work, ease of use, learning by doing and standards. Yet, a large number of IS process innovation adoptions followed no discernible pattern.

With the increased pressures to deliver software applications at a faster rate and at a lower cost, software reuse is rapidly becoming an influential technology for software development. In this paper, software reuse is viewed as a systematic approach, encompassing all attempts to leverage software assets across systems by reusing them in development efforts. This paper focuses on grounding a descriptive and explanatory theory of the individual and organizational barriers associated with the adoption of reuse. A case study research method was used. A series of five cases were selected on the basis of theoretical replication. The five sites share commonalties in issues critical to the research. The findings of this research indicate that barriers occur at both the individual and at the organizational level. One of the key findings was that barriers at the individual level are actually a consequence of the interaction of barriers caused at the organizational level. Several other significant findings emerged as well.

This paper discusses the findings of a field study of experienced systems developers which investigated the use of systems development methodologies (SDMs) in practice. Among the main findings to emerge are the following. There is a wide difference between the formalized sequence of steps and stages prescribed by a methodology and the methodology-in-action uniquely enacted for each development project. Also, there is much evidence which suggests that developers omit certain aspects of methodologies not from a position of ignorance, but from the more pragmatic basis that certain aspects are not relevant to the development environment they face. Thus, methodologies are tailored to the needs of the prevailing development environment and, being documented in a single manual often, are framed at a higher level of granularity that specifies broad activities and objectives, rather than specifying in a very detailed fashion the exact manner in which development should take place. Additionally, the findings clarify the apparently contradictory position in the literature as to whether developer experience is positively or negatively correlated with methodology use. The study would suggest that experienced developers are likely to use methodologies, albeit ones which have been heavily customized to the exigencies of the particular situation.
