Objectives This study explores the concept of "permanent temporality" within the project management frameworks of non-profit organizations dedicated to addressing Society 5.0 challenges through recurring project cycles. Material and methods By analyzing survey data from the Polish non-profit sector, the research identifies a high degree of projectification and highlights unique tensions arising from the "triple constraint" of time, budget, and scope. Results The paper utilizes a theoretical framework grounded in paradox theory, proposing "permanent temporality" as a specific contextual adaptation of existing temporality paradoxes. This approach allows for a nuanced distinction between project-oriented and non-project-oriented entities, revealing how managers must navigate the contradiction between short-term funding cycles and the long-term, sustainable implementation of an organization's mission. Conclusions The study concludes that "permanent temporality" is a pervasive phenomenon where transient project forms are multiplied into a permanent mode of activity. To manage these paradoxes, the author proposes corrective strategies such as mission-alignment audits, diversification of funding, and the implementation of "project exit" strategies. Future research should focus on international comparative analyses and exploring deprojectification as a conscious organizational choice.
