對於營造廠而言，工程進度與成本績效為影響專案成功度的主要因素，為此國際專案管理協會(PMI, Project Management Institute)為整合進度與成本管理因子以評量反映按工程進度完成之成本績效，在其專案管理知識體指南(PMBOK)一書中，提出實獲值管理(Earned Value Management)方法來評估專案預估與實際完成之進度與成本績效。
實獲值管理雖能將工程專案資料轉換為績效指標藉此有效地監督專案工期與成本的表現，但隨著專案的規模增長，專案資料將隨之複雜導致難以利用人力應用實獲值管理；為解決此問題，本研究擬應用營建資訊雲(Construction Information Cloud)，以此系統輔助營造廠換算實獲值管理的各項指標並產生圖表。
CIC係雲端營建工程資訊管理系統，此系統旨在將專案資料記錄於雲端資料庫，以不同模組區分管理各階段之專案內容。本研究將整合合約預算模組、執行預算模組、進度管理模組、採購發包模組、日報管理模組及包商計價模組等資料匯入至管理表報模組；將上述各模組資料相互整理後即可自動轉換為實獲值管理的三項基本績效指標(PV、EV及AC)，藉此產生圖表來監督專案表現。

For construction firms, project progress and cost efficiency are the primary factors influencing the success of a project. To address this, the Project Management Institute (PMI) integrates schedule and cost management factors to assess cost efficiency reflecting progress in accordance with project progress. In their Project Management Body of Knowledge (PMBOK), they introduce the Earned Value Management (EVM) method to evaluate the alignment of projected and actual progress and cost efficiency in a project.
While EVM converts project data into performance indicators to effectively monitor project duration and cost performance, the complexity of project data increases with project scale, making it challenging to implement Earned Value Management through manual efforts. To address this issue, this study aims to leverage the Construction Information Cloud (CIC) to assist construction firms in calculating various EVM indicators and generating charts.
CIC is a cloud-based construction project information management system designed to record project data in a cloud database, categorized by different modules for managing various project stages. This study will integrate data from modules such as contract budget, execution budget, schedule management, procurement and contracting, daily report management, and subcontractor billing into the management and reporting module. Once the data from these modules is organized, it can be automatically transformed into the three fundamental EVM indicators (PV, EV, and AC), generating charts to monitor project performance.
