解析 参考译文
在系统规划/计划阶段，系统分析师会通过组织初步的调查活动去研究系统需求并给出建议方案。在获得批准后，系统分析师将和客户的管理人员和系统用户坐在一起去分析当前系统的问题和发现机会点，确定项目范围和系统约束，并初步得出系统预期收益、系统开发时间和开发成本。一般而言，系统需求仅仅是描述表象，而没有触及根本的问题。系统分析员通常采用鱼骨图来进行因果分析，发现问题和机会，确定项目范围和约束，并开展了实际调查以评估项目的可行性，估算成本和收益，给出时间约束。该阶段输出的可行性报告后面是项目计划，主要包括了预估的项目工期，人力资源需求，项目成本，项目收益和后续软件开发生命周期阶段预期目标等。
