As the design process progresses, analytical techniques guide the
continuing effort to arrive at a mature design. While the design process
concerns the actual additions, deletions, and changes to the design embodied
on drawings and in engineering test models, design analysis evaluates the
ability of the design to meet performance specifications at low risk. Those
analyses oriented to the reduction of design risk include, but are not limited
to, stress and stress/strength, worst case tolerance, sneak circuit, failure
models and effects, and thermal analyses.
