Unformatted text preview: rements, and top level requirements, are initially the most interesting.
The process I use, is described in earlier INCOSE lectures [Gilb, SQC, 2005] and [Gilb 2005, CE
book, Spec QC chapter].
A small team of experts and managers will usually uncover 20-40 Major defects per page against
