Process models are fundamental for structuring Information Systems Development (ISD) endeavors and contribute significantly to ISD projects’ efficiency and effectiveness. On the one hand, agile process models have been increasingly adopted in software development. In general, the agile approach emerged to overcome the limitations of the classical models, such as the late delivery of products or the lack of response to changes. On the other hand, regarding ISD, as far as we know, there are no specific proposals for agile processes. Considering the socio-technical nature of ISD, agile processes cannot be adopted in this context without being adequately tailored. This paper describes an ISD agile process model, underlying principles, and activities. It also discusses the model’s practical feasibility, benefits, and limitations.
