内容記述 | ソフトウェア開発工数の見積において,工数は要員数(人)と工期(月)の積で表現されるが,現実には人と月は可換とはいえない.また,適正工期は開発規模によって決定され,規模を一定とすると工数,要員数はトレードオフとなる関係である.本稿では,IPA/SEC収集のプロジェクトデータセットに基づいて,工数,要員数,工期,開発規模の関係式を導出する.導出された関係式より,工期と要員数は1:1の関係ではなく,工期を半分にした場合,(開発規模が一定であっても)約2.7倍の要員数が必要となるケースがあること等がわかった.; In software effort prediction, the effort is expressed as the product of team size (persons) and project length (months): however, a person and a month are not exchangeable actually, In addition, the project length is strongly influenced by the project size. Hence, there is a trade-off among length and team size when the project size is constant. In this paper, we derive quantitative relationship of such a trade-off among effort, project size, length and team size, using a project dataset established by the Software Engineering Center (SEC). Information-technology Promotion Agecy, Japan. The derived relationship quantitatively revealed that the person and the month are not exchangeable, e.g. if the project length is shortened to 50%, the team size increase up to 270%. | |||||
