CMMI二级过程域(PP/PMC)

分类: 软件过程改进
1、项目策划(Project Planning
 
1.1、目标(Purpose)

       The purpose of Project Planning (PP) is to establish and maintain plans that define project activities.
       项目计划的目的是,建立和维护用以定义项目活动的计划
 
1.2、简介(Introductory Notes

     One of the keys to effectively managing a project is project planning. The Project Planning process area involves the following activities:
     项目策划是高效管理项目的关键(因素)之一。项目策划过程域包括以下活动
     & Developing the project plan
         开发项目计划
     & Interacting with relevant stakeholders appropriately
         与利益相关方适当的互动
     & Getting commitment to the plan
         取得对计划的承诺
     & Maintaining the plan
         维护计划
      Planning includes estimating the attributes of work products and tasks, determining the resources needed, negotiating commitments, producing a schedule, and identifying and analyzing project risks. Iterating through these activities may be necessary to establish the project plan. The project plan provides the basis for performing and controlling project activities that address commitments with the project’s customer. (See the definition of “project” in the glossary.)
    策划包括:估计工作产品及任务的属性、确定资源需求、协商承诺、产生进度表,以及识别和分析项目风险。订定项目计划的时候可能需要反复进行上述活动。项目计划是执行及控制项目活动的基础,其目标是完成项目客户的承诺。 (在术语表中查看项目的定义。 )

      The project plan is usually revised as the project progresses to address changes in requirements and commitments, inaccurate estimates, corrective actions, and process changes. Specific practices describing both planning and replanning are contained in this process area.
       项目进行中,项目计划常因下列情况而需修订:需求和承诺变更、不准确的估计、纠正措 施及过程更改。说明策划及重新策划的特定实践,也包含在本过程域之内。

      The term “project plan” is used throughout this process area to refer to the overall plan for controlling the project. The project plan can be a standalone document or be distributed across multiple documents. In either case, a coherent picture of who does what should be included. Likewise, 
monitoring and control can be centralized or distributed, as long as at the project level a coherent picture of project status can be maintained.
   术语“项目策划”在整个过程域中,被用来表示控制项目的整体计划。项目策划可以是单一的文档,或者是分布式、互相交互的多个文档。无论采用何种形式,由谁做,做什么事是必须要被清晰的描述的。同样的,监控也可以是集中的,也可以是分布式的,只要保证在项目层面,项目状态有一个清晰地图景,并且这样的状态图景是可维护的,就可以了
*****************
       For product lines, there are multiple sets of work activities that would benefit from the practices of this process area. These work activities include the creation and maintenance of the core assets, developing products to be built using the core assets, and orchestrating the overall product line effort to support and coordinate the operations of the inter-related work groups and their activities.
      对于生产线来说,有多种能够从此过程域中受益的工作活动集,这些工作活动包括建立和维持核心资产、使用核心资产开发要建设的产品,和筹划整个产品线,以支持和协调各个(相互关联工作组的(业务)运作和它们的活动。
       In Agile environments, performing incremental development involves planning, monitoring, controlling, and re-planning more frequently than in more traditional development environments. While a high-level plan for the overall project or work effort is typically established, teams will estimate, plan, and carry out the actual work an increment or iteration at a time. Teams typically do not forecast beyond what is known about the project or iteration, except for anticipating risks, major events, and large-scale influences and constraints. Estimates reflect iteration and team specific factors that influence the time, effort,resources, and risks to accomplish the iteration. Teams plan, monitor, and adjust plans during each iteration as often as it takes (e.g., daily). Commitments to plans are demonstrated when tasks are assigned and accepted during iteration planning, user stories are elaborated or estimated, and iterations are populated with tasks from a maintained backlog of work. (See ―Interpreting CMMI When Using Agile Approaches‖ in Part I.)
    在敏捷环境中,由于实施增量开发,使得对项目的计划、监控、和重新规划的频率比传统开发方式更加频繁。当整个项目的高层次计划(或工作投入)建立之后,团队会在每一次增量或迭代开发中,对实际工作进行评估,计划,和实施。团队通常不会对超过项目或(本次)迭代的已知情况进行预测,除非预测到有风险,或者遭遇到影响较大的事件,或遇到了比较严重的干扰或限制。估计是对(本次)迭代和团队的特定因素的反映,这些因素影响着完成本次迭代所需要的的时间、成就、资源以及风险。在每次迭代过程中,团队的计划,计划的监控,和计划调整是频繁发生的(每一次计划实施的时候都可能发生,例如,每天发生)。计划的承诺在以下时机被展示:当(迭代计划中的)任务被分配和接受的时候;用户故事被详细阐述或评估的时候;以及迭代被分配成任务(通过被维护工作 backlog )的时候。(查阅第一部分“使用敏捷方法时 CMMI 的说明)。

2、项目监控(Project Monitoring and Control
 
2.1、目标(Purpose)
      
      The purpose of Project Monitoring and Control (PMC) is to provide an understanding of the project’s progress so that appropriate corrective actions can be taken when the project’s performance deviates significantly from the plan.
   项目监控(Project Monitoring and Control, PMC)的目的是了解项目进度,以便在项目执行绩效严重偏离计划时,能采取适当的纠正措施。

        
2.2、简介(Introductory Notes

       A project’s documented plan is the basis for monitoring activities, communicating status, and taking corrective action. Progress is primarily determined by comparing actual work product and task attributes, effort, cost, and schedule to the plan at prescribed milestones or control levels in the project schedule or WBS. Appropriate visibility of progress enables timely corrective action to be taken when performance deviates significantly from the plan. A deviation is significant if, when left unresolved, it precludes the project from meeting its objectives.
       文档化的项目计划是监控各项活动、沟通(项目)状态及采取纠正措施的基础。项目的进展情况,主要是通过工作产品、任务属性、工作量、项目成本的实际值,与(已描述的)里程碑,或项目进度中的控制水平(区间),或工作拆分结构(WBS) 的规划值的比较来决定的。当执行绩效显著偏离原订计划的时候,保持项目进展上适当的可见度,可以使项目能够及时地采取纠正措施。如果偏离未被解决,则会妨碍项目目标的达成,那么这样的偏离就可以看做是“显著的”。
 
      The term “project plan” is used throughout this process area to refer to the overall plan for controlling the project.
      在整个过程域中使用“项目计划”一词,来代表(能够)控制项目的那个“全盘计划”。
 
      When actual status deviates significantly from expected values, corrective actions are taken as appropriate. These actions can require replanning, which can include revising the original plan, establishing new agreements, or including additional mitigation activities in the current plan.
   当项目的实际状况重大偏离预期值时,可以适当地采取纠正措施。所采取的纠正措施可能需要重新进行项目策划,而重新规划可能包括修订原计划、订定新的协议(或契约),或在现行计划中增加额外的缓解活动。
