Developing requirements for large software systems requires continuous and effective coordination of tasks, resources, and people. Research in team cognition suggests that the traditional input-process-output model is insufficient for the level of coordination needed in the development of such large systems. Coordination in these projects is greatly affected by human and behavioural factors, relying...
As software specifications for complex systems are practically never entirely complete and consistent, the recipient of the specification needs domain knowledge in order to decide which parts of the system are specified clearly and which parts are specified ambiguously and thus need inquiry to get a more detailed specification. By analyzing the evidence gained in multiple-case study, the necessary...
