包括单个项目或者根据项目和组织的需要建立的相关联的项 目群都认为是合适的 The common measures for the organization consist of process and product measures that can be used to characterize the actual performance of processes in the organization s individual projects By analyzing the resulting measurements a distribution or range of results can be established that characterize the expected performance of the process when used on an individual project 组织的公共度量由过程及产品度量项构成 可用于描述织内的单个项目的 实际过程性能 通过分析度量的结果 可以建立结果的分布或范围 当用 于单个项目时 他们描述期望的过程性能特征 Measuring quality and process performance can involve combining existing measures into additional derived measures to provide more insight into overall efficiency and effectiveness at a project or organization level The analysis at the organization level can be used to study productivity improve efficiencies and increase throughput across projects in the organization 质量与过程性能度量可以将现有的的度量项组合成为另外的衍生度量 在 项目或组织层面提供全面的效率和效果方面的更深入的理解 组织层面的 分析能被用来研究组织中项目的生产力 提升效率 并且增加组织中各项 目的生产能力 The expected process performance can be used in establishing the project s quality and process performance objectives and can be used as a baseline against which actual project performance can be compared This information is used to quantitatively manage the project Each quantitatively managed project in turn provides actual performance results that become a part of organizational process assets that are made available to all projects 预期过程性能可用来设定项目的质量及过程性能目标 亦可作为与实际项 目性能比较的基线 这些信息用来以量化方式管理项目 反过来 每个已 量化管理的项目所提供实际的性能结果 将成为组织过程资产的一部分 这些数据对所有项目是可用的 Process performance models are used to represent past and current process performance and to predict future results of the process For example the latent defects in the delivered product can be predicted using measurements of work product attributes such as complexity and process attributes such as preparation time for peer reviews 过程性能模型用于展现过去及目前的过程性能 并用来预测过程的未来的 结果 例如 在预测交付产品中潜在的缺陷时 可以通过使用诸如复杂度 这样的工作产品属性以及诸如同行评审准备时间这样的过程属性来进行预 测 When

Establish Quality and Process Performance Objectives 建立质量及过程性能目标 SP1 2 Select Processes 选择过程 SP1 3 Establish Process Performance Measures 建立过程性能度 项 SP1 4 Analyze Process Performance and Establish Process Performance Baselines 分析过程性能并建立过程性能基线 SP1 5 Establish Process Performance Models 建立过程性能模型 Specific Practices by Goal 特定目标的特定实践 SG 1 Establish Performance Baselines and Models 建立性能基线及模型 Baselines and models which characterize the expected process performance of the organization s set of standard processes are established and maintained 建立并维护描述组织标准过程集期望的过程性能特征的基线和模型 Prior to establishing process performance baselines and models it is necessary to determine the quality and process performance objectives for those processes the Establish Quality and Process Performance Objectives specific practice which processes are suitable to be measured the Select Processes specific practice and which measures are useful for determining process performance the Establish Process Performance Measures specific practice 在建立过程性能基线和模型之前 应先确定那些适合被度量的过程的 选 择过程 特定实践 质量与过程性能目标 建立质量与过程性能目标 特 定实践 这些度量对决定过程性能是有用的 建立过程性能度量项 特 定实践 The first three practices of this goal are interrelated and often need to be performed concurrently and iteratively to select quality and process performance objectives processes and measures Often the selection of one quality and process performance objective process or measure will constrain the selection of the others For example selecting a quality and process performance objective relating to defects delivered to the customer will almost certainly require selecting the verification processes and defect related measures 本目标的前三个实践是相互关联的 常常需要同时并且迭代地执行 以选 择质量与过程性能目标 过程和度量项 通常 一个质量与过程性能目标 过程或度量的选择 往往会约束其他的选择 例如 选择一个与交付给客 户的缺陷有关的质量与过程性能目标 几乎肯定需要选择验证过程以及与 缺陷相关的度量项 The intent of this goal is to provide projects with the process performance baselines and models they need to perform quantitative project management Many times these baselines and models are collected or created by the organization but there are circumstances in which a project may need to create the baselines and models for themselves These circumstances include projects that are not covered by the organization s baselines and models For these cases the project follows the practices in this goal to create its baselines and models 本目标的目的就是为项目提供需要执行定量项目管理的过程性能基线和模 型 很多时候 这些基线和模型都是由组织来收集和创建 但有些情况下 项目可能需要建立自己的基线和模型 这些情况包括项目没有被组织基线 和模型所覆盖 对于这样的情况 项目需要遵照本目标的实践去创建它自 己的基线与模型 SP 1 1 Establish Quality and Process Performance Objectives

Causal Analysis and Resolution and Organizational Performance Management 组织质量与过程性能目标提供了过程性能分析和定量项目管理活动的关注 点和方面 然而 应当注意 在建立与现有过程能力存在显著差异的质量 与过程性能目标时 需要使用在 原因分析与解决 和 组织级绩效管理 过 程域中的技术 Example Work
