IS literature states multiple benefits received from modeling and portrays UML (Unified Modeling Language) as lingua franca of software developers. However, empirical research has revealed that modeling and UML use could be considered even low. This master\u2019s thesis aims to get a clearer view on the state of practice of IS modeling. The empirical part of this thesis has been conducted as a qualitative study containing theme interviews of 13 practitioners from ten different software and IT service organizations operating in Finland. The opinions and experiences of these professionals were used to determine the role of modeling in agile IS development, discovering the needs, benefits, and challenges associated with modeling, as well as the used modeling methods and tools. The analysis of the interview data was abductive in which interview themes and preliminary analysis were derived from literature, and subsequent, detailed analysis emerged inductively from the interview material. The results show that in IS development modeling plays a clear communicative role which is emphasized in the early stages of development work and later in maintenance. UML is the most used modeling method and is used in an informal manner utilizing mainly drawing tools. The educational and experiential modeling backgrounds of the practitioners, organizational procedures, and customer requirements are factors that affect the use and perceived usefulness of modeling. Lack of resources such as time, competence, and organizational support emerges as the most prominent challenge. The opinions and experiences of IS professionals suggest that the challenges may stem from code-centric attitudes. These challenges can cause professionals to resort to informal modeling or to disregard modeling altogether which in turn may lead to communicative problems resulting in productivity and quality issues. Overcoming the challenges is likely to require several actions, such as training, guidelines, and tool development and deployment.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-06-10T09:40:29Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-06-10T09:40:29Z (GMT).
