Abstract
After checking the quality by the review, design document created in the upstream of the waterfall model is advanced to the next step. Guideline is expected to be evaluated for adequacy of the quantitative aspect to the design document. Further, this guideline may be used to determine the review embodiment. The present study proposes unit, the evaluation method and item quantitative for evaluating the quantitative validity of the design document. This can be expected that evaluation is possible with good design document as anyone can see by this method.
