建築師會選擇性的摘取建築計畫書中設計資訊。使用參與設計之前提下，客戶和建築對建築計畫書的看法並不一致，而造成雙方對計劃書型式及想藉計劃書溝通之內容意義有所差異。本次調查運用紮根理論來探討臺灣建築師、圖書館員(客戶)在圖書館建築專案中分別擁有不同關注點、意圖、獲取資訊方式和運用/理解建築計畫書之行為。圖書館員對建築計畫書會易於採取整體規範做法，而建築師則傾向採用程序性逐步操作方式。雙方作為專業人員都會追求掌控設計，而造成建築計畫書實際成為彙整設計需求之廣告。因此資訊可及性和訊息診斷性成為建築師審視建築計畫書中訊息的主要認知因素。

Architects selectively cognize design information in the design program. The “user participation design” context, and how clients and architects perceive the role of design program lead to different programming documentations and communication of different meanings. This investigation applied Grounded Theory to explore Taiwan architects, and librarians/clients communicating design under different concerns, intentions, information acquisition, and interactive programming behaviors related to library building projects. Librarians incline to normative approach to the design program, and architects adopt procedural design operations, while both professionals pursue design control, and the design program functions as a design requirements advertisement. Thus, information accessibility and message diagnosis could be major factors for architects’ cognition of information in the design program.
