    I have no numbers recorded to provide. We ship our application with not
    only 100% of its TDD unit tests passing, but also 100% of its acceptance
    tests passing.

    Sometimes we'll find areas that don't work properly as in a classical
    bug (for example an exception being throw) other times we see that a
    requirement defect has occurred in that a feature is missing.

    The classical bugs are very rare - again no numbers sorry.
    The feature defects are more common, but not in so large a number that
    we - or rather - our customer is concerned by it.
