However, fundamental assumptions of agile development are challenged when applying the methods at a very large scale. An interpretative revelatory case study on one of the largest software development programmes in Norway shows how agile methods were adapted and complemented with practices from traditional methods to handle the scale. The programme ran over four years with 12 co-located development teams and a total of 175 people involved. The case study was conducted retrospectively using group interviews with 24 participants and documents. Findings on key challenging areas are reported: customer involvement, software architecture, and inter-team coordination. The revelatory study also suggests refinements of a research agenda for very large-scale agile development. 收起
