Conway's law is an adage named after computer programmer Melvin Conway, who introduced the idea in 1967;〔http://www.melconway.com/Home/Conways_Law.html〕 it was first dubbed Conway's law by participants at the 1968 ''National Symposium on Modular Programming''.〔Yourdon, E. N., and Constantine, L. L. ''Structured Design'' (Prentice Hall, 1978), p. 400〕 It states that Although sometimes construed as humorous, Conway's law was intended as a valid sociological observation. It is based on the reasoning that in order for a software module to function, if it has multiple authors they must communicate frequently with each other. Therefore, the software interfaces structure of a system will reflect the social boundaries of the organization(s) that produced it, across which communication is more difficult. ==Variations== Eric S Raymond, an open source advocate who co-founded the Open Source Initiative, restated Conway's law in ''The New Hacker's Dictionary'', a reference work based on the Jargon File he maintained for years. The organization of the software and the organization of the software team will be congruent, he said. Summarizing an example in Conway's paper, Raymond wrote that "If you have four groups working on a compiler, you'll get a 4-pass compiler". James O. Coplien and Neil B. Harrison stated that "If the parts of an organization (e.g. teams, departments, or subdivisions) do not closely reflect the essential parts of the product, or if the relationship between organizations do not reflect the relationships between product parts, then the project will be in trouble... Therefore: Make sure the organization is compatible with the product architecture". The impact of Conway's Law can be seen in the design of corporate websites. Nigel Bevan, a usability expert, states that "Organisations often produce web sites with a content and structure which mirrors the internal concerns of the organisation rather than the needs of the users of the site."〔(【引用サイトリンク】format=PDF )〕 A similar effect may be found when websites undergo design by committee. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Conway's law」の詳細全文を読む スポンサード リンク
