Large-scale agile frameworks suggest several practices for coordination between teams in software development projects. These prescribed coordination practices are often described as how to be performed in detail but without explaining the intended impacts. At the same time, agile values emphasise the need for tailoring practices that are not helpful. This study examines how three agile coordination practices influence accountability, predictability, and common understanding, which are important conditions for coordination. A qualitative research strategy was used to investigate three case organisations that implemented the scaled agile framework (SAFe): one bank, one government agency, and one department within the automotive industry. The empirical data consists of 28 semi-structured interviews and observations. The findings show the differing impacts of three investigated agile coordination practices and how the tailoring of practices affects coordination.
