Since the last eNews submission in April 2018, the SDP Consortium successfully submitted a documentation pack of roughly 30 documents for its Pre-CDR, M20, milestone to the SKAO. The documentation pack included key Systems Engineering documents, Interface Control Documents (ICDs) and an updated snapshot of the latest SDP Architecture views since the M19 submission and review in November 2017.
In late June, a two-step review process was undertaken between SDP Consortium representatives and the SKAO M20 review panel. The first step was a documentation review process where the objective was to understand and assess the suitability and risks associated with the SDP design before entering the CDR review process. The second step was a face to face meeting which first analysed the suitability of SDP software architecture to meet the needs of its stakeholders, conducted using the SEI ATAM (Architecture Trade-Off Analysis Method) process and based on scenarios generated previously and then discussed observations made against the documentation pack in the first step.
