Software architecture design meetings are instances where architects discuss design concerns and make decisions about the significant elements of a software system. There is little empirical evidence about how architects make design decisions because capturing reasoning and decisions is intrusive and/or expensive, design meetings combine verbal and graphical interventions. This article describes Design Verbal Interventions Analysis (DVIA), a technique to identify design decisions in recorded design meetings by subjecting verbal interventions to transcription, classification and mapping to a decision model. The approach is illustrated with a case study of senior undergraduate student teams that were video-recorded while designing a command-and-control center for the pan-Andean spatial project. The DVIA analysis showed that the discussion developed as a set of cycles where designers engaged in concurrent resolution of several design issues at once, "jumping" among them and yet closing issues. This study shows empirically the viability of identifying design decision from the recording of verbal interventions, and point to possible ways to record and analyzes them.
