設計工作的品質一直沒有量化的方法。初次正確率（First Time Correctness Ratio, FTCR）是一工程量化品質指標，設計工作找出重點項目，定期檢查，算出項目第一次就做正確的比率。此指標資料收集容易，即時計算品質分數，可簡化品管的繁雜程序。
整個FTCR中最重要的工作為建立設計重點項目檢查，本研究為公路設計建立檢查表。參考設計管理理論、個案顧問公司工作指導書，及公司層級的部分程序，並多次訪談設計者與業主。文獻理論提出一定的設計管理作法，但訪談設計者發現，由於工作量大，一般工程師都不希望增加設計管理的負擔。但從業主角度，肯定設計檢查表的優點，如明確標準、釐清責任，但不宜加入太細項目。因此，為達業主期望，設計檢查表是設計管理的基本要求。
檢查表架構分成初設、細設兩階段。初、細設下有前置作業、專業工作、協調整合、設計輸出等四類工作。檢查表項目分成三個層次，第一層為大項目，第三層為檢查最細項，依各專業不同可填入，檢查者通常在第二或第三層勾選。
檢查表建立後，以四個公路設計計畫測試，共填寫十次。由設計者及審查者勾選項目次數中計算FTCR分數，可呈現不同階段、面向、層次的設計品質績效。而且，檢查工作及填寫的時間花費不多。FTCR能發揮品質管理的實質功能，且滿足ISO 9000：2000對績效量測與改善的規定。

The quality of engineering design work is difficult to quantify. The First Time Correctness Ratio（FTCR）is a quantitative quality measure that finds out important design items（activities）, checks them regularly, and calculates the ratios of work items being done right the first time. The data for FTCR is easy to collect and the quality score can be obtained immediately to simplify the quality procedure.
The key in FTCR is to establish checklists for design work. This research sets up a checklist for highway design based on design management theory, Work Instructions of consultant company, relevant Quality Procedures at the consultant company level, and interviews with designers and owners. Because of heavy work load, designers do not want the burden of design management. But the owners acknowledge the advantages of checklists such as unifying standards and distinguishing responsibilities, without being too detailed. Therefore, in order to meet owners’ expectation, the checklist is the basic requirement for designer’s management.
In terms of structure and composition, the checklist is divided into preliminary and detailed design stages, under which there are four dimensions: starting activities, discipline work, coordination/ integration, and design output. Under the four dimensions, check items are divided into three layers in which the first layer includes major ones and the third most detailed ones. The reviewer checks the items at the second or third layer.
After the checklist was set up, it was tested on four highway design projects and filled out ten times in three months. The FTCR scores were calculated from the reviewer’s evaluation of the work items done. The reviewer’s time spending for reviewing and filling out is less than one hour each time. FTCR can develop the essential function of quality management, and meet the requirement of performance measurement and improvement stipulated by ISO 9000：2000.
