On custom software development, to validate the price of software, price is sometimes estimated with multiplying software development effort by unit cost of software engineers. To multiply the unit cost, we should know the participation rate of developers based on their roles such as project manager. However, software user companies do not always know such rate. Hence, the goal of our study is to support unit cost estimation without using the rate of developers. To achieve the goal, we clarified factors which affect the unit price, and showed the distribution of the unit price on each factors. In the analysis, using 99 data points where missing values were eliminated by listwise deletion, we applied multiple linear regression. Additionally, we applied bivariate analysis, using 220 to 446 data points where pairwise deletion was applied. As a result, we clarified the relationships between the unit price and some factors such as programming language and contract type on the basic design phase.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"972","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"960","bibliographicIssueDates":{"bibliographicIssueDate":"2022-04-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"63"}]},"relation_version_is_last":true,"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20729/00217600","subitem_identifier_reg_type":"JaLC"}]},"weko_creator_id":"44499"},"id":217708,"updated":"2025-01-19T15:23:47.425895+00:00","links":{}}
