In this process we have hit the limit of what can be achieved with a detailed software design that is primarily captured in pdf/word documents.\n  Trade-offs between hardware and calibration software are required to meet stringent science requirements. To support such trade-offs, more software needs to be developed in the early phases of the project: simulators, archives, prototype recipes and pipelines.
