PurposeThe aim of this article is to give an overview of the development and current state of projectification research. The inquiry was driven by a threefold research question: How has projectification been understood and defined over time, what has the trajectory of the development been and what are the main trends and emerging ideas?Design/methodology/approachThe article is an integrative literature review of research done on the notion of projectification to date. An interdisciplinary, integrative literature review was conducted using Scopus and Web of Science as primary sources of data collection. The full data set consists of 123 journal articles, books, book chapters and conference contributions. With the data set complete, a thematic analysis was conducted.FindingsAmong other things, the review outlines the development and scope of projectification research from 1995 until 2021 and discusses four emerging images of projectification: projectification as a managerial approach, projectification as a societal trend, projectification as a human state and projectification as a philosophical issue. These characteristics emphasize some common features of each of the images but also imply that the way projectification is understood changes depending on the paradigmatic perspective taken by the researcher, the time and place in which the observation was made and the level of observation.Originality/valueThe authors have outlined and discussed four images of projectification – projectification as a managerial approach, projectification as a societal trend, projectification as a human state and projectification as a philosophical issue – where each image represents a special take on projectification with some prevalent characteristics. By doing this, the authors provide a systematic categorization of research to date and thus a basis upon which other researchers can build when furthering the understanding of projectification at large.
