Preparation to increase LOW CSP requirement coverage

(Goal 1) - Develop AA1/AA2 sub-system functionality

Objective:

We need to separate out the requirements marked as inspection and identify the inspection required. We currently reviewed various sources to estimate test coverage of subsystem related to requirements with inspection as verification method. We need to create a check list for these and have more constructive discussions with subsystems related to implementation timelines in order to align for AA1 delivery.

To increase AA0.5 test coverage we need to add more test cases (need to identify which requirements have enough information define test cases), in additional, some requirements need more information for L2 level testing and this has to be discussed and addressed to enable test case definition

To broaden AA0.5 test coverage by adding test patterns expanding with the AA milestone for future proving

Aim:

• Obtain, in collaboration with commission scientist, uses cases regarding how the telescope will be used in order to define test cases 
• Define a checklist with steps to inspect for requirements with review method inspection
• Clarify and clean up requirements in co-operation with system engineering 
• Prioritize the requirements on which should be test first in order to increase AA0.5 coverage

Business value:

Currently the full coverage is 37.3 % and the partial coverage 22.0% of the AA0.5 requirements. For AA1 there is an additional 6 requirements. We strive for a coverage, for our test and demonstrate requirements, of 80% for our LOW CSP AA1 FAT.
