Electronic records management is a part of the information management domain. Knowledge about how electronic records are used is important to design e.g. electronic records management systems (ERMS), when records at creation must meet stated and implied needs both present and future. Knowledge about the use of electronic records can result in design implications for information systems managing records. The use of electronic records has been studied, and variations in that use, by applying a temporal lens. The research aims to study how temporal structures in a knowledge intensive and time-critical organization affect the use of electronic records. The Swedish police have been studied, guided by the following research question: “How do different temporal structures in operational police work affect the use of electronic records?” The study uses qualitative research. The research shows that the use of electronic records shifts depending on different temporal structures, and moves from traditional user, mediated user, “bricoleur”, and producer. The shifts and variations in the use of electronic records are important considerations in design, when all these different users’ needs must be fulfilled.
