Summary of key concepts in this research and their connections to similar concepts in the literature

	Definition in this study	Related concepts
Relational interface	Relational interfaces refer to the touchpoints through which the resource bases of buyer and supplier are connected by exchange activities (Araujo et al., 1999)	We found several studies referencing Araujo et al. (1999) with different terms like buyer-supplier interface (Holma et al., 2022), supplier interfaces (Ferreira and Lind, 2023) and organizational interface (Sundquist and Melander, 2021)Resource interface: Specific contact points between two resources defined along relevant technical, economic, and social dimensions” (Baraldi, 2003, p. 18)
Relational friction	Results of the destabilizing forces or movements toward heavy resource ties, activity links or actor bonds occur as a result of changes within the established relational interfaces of actors (authors’ definition), such as seeking innovative processes in standardized traditional environments like public procurement	Friction (actor–network perspective): Performative tension between actors and networks while a new resource or process is adopted in a network (Mattila, 2017)Resource friction: Result of any destabilizing force or movement of resources in relation to other interconnected resources (Håkansson and Waluszewski, 2002a, 2002b)Network tension: Discomfort generated by ambiguity that can have various sources, such as contradictory and unclear communications, the absence of communication, a lack of sufficient planning, and incongruity between actors’ aims (Tóth et al., 2018)
Coping activities	Activities to reduce the effects of the relational frictions between actors	Coping strategies: Approaches to resolve frictions and misalignments between actors (Mattila, 2017)Lubricants: Elements that reduce friction in resource contact points (Hauke-Lopes et al., 2023)
Friction distribution	Relational frictions can trigger other frictions, which we categorized by elaborating on (Hoholm and Olsen, 2012): Direct frictions: Relational frictions occurring at the buyer–seller interfaces of our focus Indirect frictions: Relational frictions that arise with interfaces involving other actors in the network	Friction effects (direct and indirect): They can be direct (local) or distributed across resource interfaces and affect other resources (Hoholm and Olsen, 2012)
