Research in software engineering has made significant strides in advancing sociotechnical analysis and pioneering research methodologies to effectively tackle challenges prevalent in the industry. This evolution presents an opportunity for knowledge transfer to other technology sectors, such as integrated circuits, where research on this topic is limited. This article presents a case study to identify challenges in delivery processes on mixed-signal projects at a specific design house, considering both technical and social perspectives. We performed 17 semistructured interviews and examined the available process documents. We analyzed the data using coding techniques. We mapped 14 constructs, 13 propositions, and two explanations to identify the challenges faced by mixed-signal teams. This study discusses the social aspects of semiconductor's research, and we propose a list of possible delivery challenges in the context of the focal company. The suggested root causes of the challenges encountered in mixed signal projects are primarily attributed to two fundamental issues: the incipient specification processes and the absence of well-established collaborative practices among cross-functional teams. Requirement engineering and agile studies provide insights into the organization's implications for improvement.
