The second issue of the SJIS volume 22 features four research articles. The first article by Jan Recker and Michael Roseman presents a study on the development and validation of an instrument to measure user acceptance of process modeling grammars. The main contribution of the study is a procedural model for developing measurement instruments that ensures high levels of reliability and validity in empirical research. In the second article, Tina Blegind Jensen and Annemette Kjærgaard explore the ways in which users make sense of electronic patient record systems. The study contributes to existing literature by providing a detailed account of how users’ early sensemaking of a technology influences their subsequent actions and reactions towards it. The third article by Brit Ross Winthereik offers a theoretical expansion of the concept of enactment to understand systems development practice. The study highlights that implementation projects produce good as well as bad effects in situations where pre-set goals and expectations mix with everyday routines and activities. In the fourth article, Kristin Børte and Monika Nerland examine how a team of software professionals estimates the effort of a software project using a judgment-based, bottom-up estimation approach. Analyzing the interactional process through which the estimation tasks were executed, the study shows that software effort estimation involves complex series of explorative and sensemaking actions.
