Cooperation and collaboration are generally an inherent part of everyday practice, and particularly among nurses. However, the technologies that support these practices are still inadequate. In this study, we present and discuss the use of classifications in nursing practice, and highlight the collective re-construction of classifications that emerge over time. Specifically, we study how the negotiation between global classifications and local practice takes place with long-term use, and depict this dynamic interaction as a pendulum movement. Furthermore, we characterize this standardization as a collective re-construction grounded in everyday practice. This paper contributes to the body of research on this topic by doing the following: (i) characterizing the process of standardization as a pendulum movement; (ii) drawing out theoretical perspectives for standardization as a collective, emerging accomplishment; (iii) stating the practical implications of our perspective. Finally, we co...
