Functional Coverage

Note

Functional coverage graphs are useful for designers to estimate their design time, and help account for two situations:

• “We didn’t know about that”

• “We didn’t think about that”

These two are, by definition, hard to time-box and conceptually malleable as management risks during project planning, and later materialize as technical risks during development

Presenting estimates in such a fashion helps compartmentalize the development into phases, and buffers for these occasions
