计算机系统技术和标准的不断改进，使得信息系统生命周期规划的新方法更加实用和经济。这种名为“开放系统业务流程重组”的新方法有以下关键成功因素（CFS）。首先，任务关键型业务流程必须有负责持续改进的主管。其次，必须对关键业务流程进行基准测试和评估，以消除所有步骤和功能中的浪费。第三，系统架构必须围绕开放系统框架构建，以支持关键流程。本文展示了业务流程再造的关键要素及其与提高业务竞争力的联系。

THE CONTINUED IMPROVEMENT OF COMPUTER SYSTEMS TECHNOLOGY AND STANDARDS MAKES NEW APPROACHES TO INFORMATION SYSTEMS LIFE CYCLE PLANNING MORE PRACTICAL AND AFFORDABLE. THIS NEW APPROACH--ENTITLED BUSINESS PROCESS RE-ENGINEERING FOR OPEN SYSTEMS HAS THE FOLLOWING CRITICAL SUCCESS FACTORS (CFS). FIRST, MISSION CRITICAL BUSINESS PROCESSES MUST HAVE EXECUTIVE OWNERS WHO ARE TASKED FOR THEIR CONTINUOUS IMPROVEMENT. SECOND, KEY BUSINESS PROCESSES MUST BE BENCHMARKED AND ASSESSED FOR ELIMINATION OF WASTE IN ALL STEPS AND FUNCTIONS. THIRD, SYSTEMS ARCHITECTURES MUST BE BUILT AROUND THE FRAMEWORK OF OPEN SYSTEMS TO SUPPORT KEY PROCESSES. THIS PAPER SHOWS THE CSFS OF BUSINESS PROCESS RE-ENGINEERING AND THEIR LINK TO IMPROVED BUSINESS COMPETITIVENESS.
