在变更管理领域，高零件数量的复杂产品的制造一直是一组独特的困难。为了更好地响应当今的市场需求，需要通过不断引入新功能来满足需求快速变化的更小、更多样化的细分市场的期望。为了实现盈利，公司必须严格控制ECO（工程变更单）流程。本文概述了利用信息技术和开发集成工程信息系统应对变更管理挑战的新策略。 该系统是使用UNIX工作站、RDEMS、专家系统和技术出版——数据管理软件开发的。

MANUFACTURING OF COMPLEX PRODUCTS WITH HIGH PARTS COUNT ALWAYS PRESENTED A UNIQUE SET OF DIFFICULTIES IN THE AREA OF CHANGE MANAGEMENT. TO BE MORE RESPONSIVE TO MARKET DEMANDS TODAY REQUIRES MEETING EXPECTATIONS OF SMALLER AND MORE DIVERSE MARKET SEGMENTS WITH RAPIDLY CHANGING NEEDS BY CONSTANTLY INTRODUCING NEW FEATURES. TO DO THIS PROFITABLE, THE FIRM MUST HAVE TIGHT CONTROL OF THE ECO (ENGINEERING CHANGE ORDER) PROCESS. THIS PAPER OUTLINES A NEW STRATEGY IN DEALING WITH THE CHALLENGES OF CHANGE MANAGEMENT BY TAKING ADVANTAGE OF INFORMATION TECHNOLOGY AND DEVELOPING INTEGRATED ENGINEERING INFO SYSTEM. THE SYSTEM IS DEVELOPED USING UNIX WORKSTATIONS, RDEMS, AND EXPERT SYSTEM, AND TECH PUBLISHING--DATA MANAGEMENT SOFTWARE.
