Although prior research has proposed frameworks, patterns, and usercentered approaches to support explainability, there is limited empirical understanding of how existing Requirements Engineering (RE) practices support explainability requirements across the RE lifecycle, especially in an industrial context. This paper reports early ﬁndings from an ongoing industry-based study investigating how explainability requirements are elicited, speciﬁed, and validated using established RE techniques. We conducted a multi-phase qualitative study with eight practitioners at Daimler Truck, employing think-aloud protocols and moderated group discussions across requirements elicitation, speciﬁcation, and validation steps. Our preliminary analysis reveals recurring challenges across all steps, including conceptual ambiguity during elicitation, limited testability and expressiveness during speciﬁcation, and fragmented validation due to vague criteria and regulatory uncertainty. These ﬁndings indicate that current RE practices provide limited support to systematically address explainability requirements. The paper contributes empirical insights into step-speciﬁc and cross-cutting challenges and outlines a research vision toward developing an empirically grounded RE framework for explainable AI-based systems.  \nKeywords  \nExplainable AI, Requirements Engineering, Framework Proposal, User Study, Focus Group  \n1 Introduction  \nArtiﬁcial intelligence (AI) is increasingly used in domains such as medicine [6, 18], law [17], autonomous driving [3], and loan application approval [24] . In these and other high-stakes settings, AIbased systems often support or inﬂuence critical decision-making processes. Consequently, responsible users, including physicians, judges, drivers, and bankers, require varying levels of explanation to appropriately trust, assess, and act on AI outputs. Ensuring that AI decisions are interpretable is essential for safe, responsible, and legally compliant AI deployment [21, 22] .  \nStefan Wagner TUM School of CIT, Technical  \nUniversity of Munich  \nHeilbronn, Germany  \n[stefan.wagner@tum.de](stefan.wagner@tum.de)  \nFrom a software engineering perspective, developing explainable AI-based systems requires eﬀective methodologies to elicit, specify, and validate explainability-related requirements. However, as explainability has only recently emerged asa key non-functional requirement [19], practitioners currently receive limited support for systematically integrating explainability into Requirements Engineering (RE)processes. Explainability poses particular challenges for RE due to its context-dependent, multi-dimensional, and humancentered nature.  \nPrior research has increasingly investigated explainability from an RE perspective by proposing conceptual frameworks, experi  \nence reports, and user-centered methods that supportspeciﬁcexplainability  \nrelated activities [5, 29, 30] .
