Background: Sustainable organizational change has become one of the greatest challenges facing contemporary businesses. The metal manufacturing industry is important in the transition, due to its impact on global GDP and the climate. SMEs covers a large portion of the metal manufacturing industry, where their transformation is crucial as well. Problem: Despite the importance of sustainable change, there is limited research on how manufacturing SMEs can effectively manage a sustainable transformation. This gap necessitates elucidating the context of SMEs in sustainability, and exploring methods for sustainable change management within these organizations.  Purpose: The aim of this research is to explore sustainability and organizational change in the context of manufacturing SMEs, to provide a deeper understanding on how manufacturing SMEs can sustainably transform their business activities through adequate methods and processes. Method: This research takes on the philosophical position of critical realism and utilizes a qualitative, explorative, and inductive approach. Semi-structured interviews were conducted with ten managers from manufacturing SMEs. A thematic analysis was also adopted to extend the previous research.  Conclusion: Manufacturing SMEs adopt various sustainability activities, in line with the triple bottom line. They are also going towards a more formal approach for sustainability. Economic performance and sustainability go together for manufacturing SMEs, whereas more knowledge is connected to higher altruistic motivations and clear sustainability strategies. A combination of continuous incremental and transformational change is evident. This research found a six-step process for SMEs sustainable change management, elucidating their more flexible and adaptive culture alongside specific advantages and challenges. Their capabilities of learning and an informal culture facilitates fast decision-making and the continuous improvement of their practices, facilitating economic performance and sustainable change.

Det drivs många utvecklingsprojekt inom offentlig sektor, men det saknas kunskap om hur dessa projekt kan bidra till ett hållbart utvecklingsarbete. Syftet med avhandlingen är att förstå och förklara hur resultat och kunskap från utvecklingsprojekt kan integreras i den ordinarie verksamheten i offentliga organisationer och bidra till långsiktiga effekter, som har ett värde för brukarna, organisationen och de anställda. I forskningen saknas en etablerad begreppsapparat för att studera hållbar utveckling i organisationer. En utmaning har därför varit att identifiera och analysera tidigare forskning, för att därigenom definiera begreppet hållbart utvecklingsarbete och viktiga förutsättningar för ett sådant arbete. Den teoretiska referensramen baseras på ett institutionellt perspektiv: nyinstitutionell organisationsteori kombineras med Giddens struktureringsteori och sociologisk professionsteori, som synliggör spänningar mellan konkurrerande styrformer som byråkrati, marknad och professionalism. Avhandlingen utgår från en interaktiv forskningsansats och består av två empiriska delar: en  kvantitativ enkätstudie som inkluderar 348 utvecklingsprojekt inom vård och omsorg samt en kvalitativ flerfallstudie av fyra utvecklingsprojekt. Studierna visar att olika faktorer främjade projekten på kort och lång sikt. Tydliga projektmål, styrning och kompetent projektledning hade betydelse för de kortsiktiga projektresultaten, men mycket begränsat påverkan på den långsiktiga hållbarheten. Istället var det ett aktivt ägarskap, och andra faktorer kopplade till ledningen i mottagarorganisationerna, som tydligast främjade ett hållbart utvecklingsarbete. Studierna visar även hur konflikter och motstånd i projekten påverkade förutsättningarna för långsiktig hållbarhet. Det gällde konflikter mellan olika yrkesgrupper, mellan ledning och professionella samt mellan byråkratiska och professionella styrformer. En slutsats är att en analysmodell för hållbart utvecklingsarbete behöver komplettera ett organisatoriskt och institutionellt perspektiv med ett professionsperspektiv. / There are many development projects in the public sector, but there is a lack of knowledge about how these projects can be made sustainable. The aim of the thesis is to explain how project results and knowledge can be integrated into public organizations and contribute to long-term effects and value for clients, organizations and employees. The scientific literature lacks an established conceptual framework for studying sustainability in organizations. Therefore, it has been a challenge to identify and analyze previous research in order to delineate and define the concept of sustainable change in organizations. The research is based on an institutional perspective: neo-institutional theory in combination with Giddens' structuration theory and sociological profession theory, which reveal tensions between three competing logics of control, i.e., bureaucracy, market and professionalism. The method is inspired by an interactive research approach and comprises two empirical parts: a quantitative survey study, including 348 development projects in health and social care, and a qualitative multi-case study of four development projects. The studies showed that different sets of factors supported short-term project success and long-term sustainability. Project-related factors, such as goal setting and project management, had little impact on sustainability. Instead, it was primarily active ownership, and other factors related to management of the recipient organization, that influenced the routinization of project results. The studies also exposed several conflicts and tensions that affected project sustainability. There were conflicts between occupational groups, between management and professionals, and between the logic of rational, bureaucratic management and the logic of occupational professionalism. Thus, understanding sustainable change in organizations requires a professional perspective to complement the organizational and institutional perspectives.
