This case study illustrates distinctive features of case study methodology that were responsive to context in ways not often seen in case study research. Located in Alberta, Canada, the study explored the factors that supported or hindered licensed practical nurses' ability to work to the full scope of practice assigned to them by legislation but that they had not been able to fully implement in the field. While the case study method as described by Robert K. Yin provides a number of useful design components, there are several limitations, most particularly with regard to lack of rigor and the potential for bias. Due to the politically charged environment of this study, particular attention was given to devising an objective method for the selection of case study sites as well as to a number of other strategies to strengthen study rigor. An extensive literature review, theory development, a research framework, the success case method, a province-wide survey, and statistical modeling were used to produce an objective and defensible platform for site selection as well as to enhance study rigor. Study findings were well received by the diverse stakeholders who represented key sectors in the health-care system. [This content is provided in the format of an e-book.]
