Various preventive measures have been developed or proposed to manage the situation, including digital preventive technologies to support contact tracing or physical distancing. The complexity of the pandemic and the rapidly evolving nature of the situation pose challenges for the design of effective preventive technologies. The aim of this conceptual paper is to apply a systems thinking model, DSRP (distinctions, systems, relations, perspectives) to explain the underlying assumptions, patterns, and connections of the pandemic domain, as well as to identify potential leverage points for design of preventive technologies. Two different design approaches, contact tracing and nudging for distance, are compared, focusing on how their design and preventive logic are related to system complexity. The analysis explains why a contact tracing technology involves more complexity, which can challenge both implementation and user understanding. A system utilizing nudges can operate using a more distinct system boundary, which can benefit understanding and implementation. However, frequent nudges might pose challenges for user experience. This further implies that these technologies have different contextual requirements and are useful at different levels in society. The main contribution of this work is to show how systems thinking can organize our understanding and guide the design of preventive technologies in the context of epidemics and pandemics.<\/jats:p>","DOI":"10.3390\/informatics10010007","type":"journal-article","created":{"date-parts":[[2023,1,11]],"date-time":"2023-01-11T04:45:58Z","timestamp":1673412358000},"page":"7","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Addressing Complexity in the Pandemic Context: How Systems Thinking Can Facilitate Understanding of Design Aspects for Preventive Technologies"],"prefix":"10.3390","volume":"10","author":[{"given":"My","family":"Villius Zetterholm","sequence":"first","affiliation":[{"name":"Department of Informatics, Linnaeus University, 39231 Kalmar, Sweden"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5292-3833","authenticated-orcid":false,"given":"P\u00e4ivi","family":"Jokela","sequence":"additional","affiliation":[{"name":"Department of Informatics, Linnaeus University, 35252 V\u00e4xj\u00f6, Sweden"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"111676","DOI":"10.1016\/j.envres.2021.111676","article-title":"COVID-19 and emerging infectious diseases: The society is still unprepared for the next pandemic","volume":"202","author":"Frutos","year":"2021","journal-title":"Environ.
