<p><P>PROBLEM TO BE SOLVED: To provide a method for constructing a characteristic tree for classifying a functional requirement and a non-functional requirement (performance, reliability, reusability, and the like) especially and drawing distinction between common characteristics matching both requirements and variable characteristics. <P>SOLUTION: In required specification extraction, the characteristic tree performing classification between the common characteristics and the variable characteristics based on characteristic analysis and between a functional proposal and a non-functional proposal is constructed, a requirement item is evaluated, and a proposal list for the requirement is outputted. A plurality of characteristic tree patterns are previously set in a characteristic tree pattern table, a characteristic tree pattern is selected from the characteristic tree pattern table for constructing the characteristic tree, and an attribute of the characteristic item matching the requirement item is evaluated for indicating a recommendation point. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
