Challenges and Solutions for the SKA TM Architectural Team

The SKA (Square Kilometre Array) Telescope Manager (TM) [1] is the core package of the SKA Telescope: it is aimed at scheduling observations, controlling their execution, monitoring the telescope health status, diagnosing and fixing its faults and so on. Following the adoption of the Views and Beyond (V&B) approach [2] of the Software Engineering Institute (SEI [3]), it was discussed and agreed upon to take the opportunity to setup a TM Architecture Team (TMAT) composed by a combination of team members (who drove much of the work towards the main deliverables for the final review) and others (who can help shape the architectural design). The TMAT has to make sure that the main deliverables are well aligned with the overall TM architecture (including ensuring that the SEI approach is followed to the level agreed upon), and that there are no gaps and that cross-cutting issues are taken care of properly. This paper wants to analyze the challenges that the team has to face together with the solutions proposed to ensure that the quality of the deliverables are reached.
