Handling CONCERNs in the design

• Create the new CONCERN (relating it to the element causing  the CONCERN). • Take action to resolve the CONCERN.  Generally this is done  via a Trade Study or another engineering team action that can  be documented (for example – a calculation, technical study,  research, etc.). • Close the CONCERN based on the results of the engineering  study or analysis. • Generate a “new” element in the architecture to reflect the  decision (for example – a new requirement or constraint on  the system design).
