【摘要】 现今大部分软件企业的项目管理,都是基于风险的项目管理。基于风险的项目管理模式往往由于太着眼于风险而忽略了生产流程本身的核心价值流程,导致部分不具备价值的步骤存在于软件生产流程当中。软件测试行业由于需要进行大量的手动测试,因此软件测试在整个软件生产的流程中占据了一半以上的人力成本的支出。高昂的软件测试人力成本无疑成为了软件生产企业的痛肋,也成为制约软件企业的竞争力的一大因素。针对以上问题,软件企业都在寻求一种适用于软件测试的改进方案,希望能实现软件测试流程改进,从而达到降低软件测试人力成本的目的。精益六西格玛方法论在制造业被认为是当今最快速最有效实现改进的方法。但在服务业,尤其是在软件测试行业,精益六西格玛结合用于软件测试的改进方面的研究在国内外都比较少。本文运用精益生产及六西格玛方法论结合的方法,以一具体的软件测试项目作例子,深入地分析两方法论结合运用在软件生产上的可行性及有效性,并运用真实的统计数据作检验分析,来证明此方法论能持之有性地帮助软件测试实现可持续发展的成本减省的目标。在具体的项目实施的实例中,本文针对软件测试遇到的实际问题,面对的影响因素等,运用精益六西格玛的相关理论,论述了以成本减省为目标的改进项目,通过立项、“网”视、简化及标准化为软件测试提供一套可行、可控、可持续自我完善的改进模型,并运用统计方法对改进方案进行实施控制及成果分析。让大家可以清楚看到此方法论在软件行业的实际运用结果,为软件行业提供具现实意义的参考。更多还原

【Abstract】 Most project management in software company by now, are risk based project management. The model of risk based project management often takes the risk into consideration too much, which leads to many non-value add process exist in the software development life cycle.Software testing is a great consumer of the human resource, which occupied more than half resource in the software produce. There is no doubt that the high cost of human resource in software testing part is a big pain point of the software company, and it is also harm to the company’s competitiveness in the market.Due to the issue above, most software companies is looking for an improvement methodology which can improve the software testing progress, which can low down the cost of testing. Lean Six Sigma, which is considered to be the most efficient and fastest way to perform the improvement in the industry company. In this paper, it is used a real software testing project of a certain company, to identify the possibility and efficiency of the combination of Lean and Six Sigma into one. All these are based on the real statistical data and it is also shown it is verification result by statistical tools, making the purpose of cost saving to be shown in front of the audience. During the sample showing, it is used the Lean Six Sigma as the main track to perform the improvement plan, which should be a meaningful example for the software testing domain.更多还原
