3 Structure of the TMMi
The structure of the TMMi is largely based on the structure of the CMMI. This is a major benefit because many people/organizations are already familiar with the CMMI structure. The CMMI structure makes a clear distinction between components that are required (goals) or recommended (specific practices, example work products, etc.) to implement. This aspect is also included in the TMMi. In this chapter, the components and structure of the TMMi are described. In addition the support provided by the CMMI to a TMMi implementation is described.
TMMI的构架很大程度上依赖于CMMI的架构。这样做最大的好处是很多人或组织对于CMMI的构架很熟悉。CMMI的架构在不同的等级间很清晰的区别来描述目标和建议。这个概念同样在TMMI中适用。在这个章节，各个组件和架构被描述。另外也描述了一些CMMI对TMMI提供的支持。
3.1 Required, Expected and Informative Components
The various components are grouped into three categories: required, expected and informative.
需求，期望和信息组件
每个组件从3个方面来归纳：需求，期望和信息
3.1.1 Required Components Required components describe what an organization must achieve to satisfy a process area. This achievement must be visibly implemented in an organization’s processes. The required components in TMMi are the specific and generic goals. Goal satisfaction is used in assessments as the basis for deciding if a process area has been achieved and satisfied.
需求组件描述了组织为了满足过程域应该做到哪些目标。这些做法必须被组织认真执行。TMMI需求组件分为通用和指定的目标。目标满意度被使用来评估过程域是否达到和满足。SG/GG
3.1.2 Expected Components Expected components describe what an organization will typically implement to achieve a required component. Expected components guide those who implement improvements or perform assessments. Expected components include both specific and generic practices. Either the practices as described or acceptable alternatives to the practices must be present in the planned and implemented processes of the organization, before goals can be considered satisfied.
期望组件描述了组织通常如何做来满足需求组件。需求组件指导了谁执行过程提高或者做评估。期望组件包含了通用和特定实践。SP/GP
3.1.3 Informative Components Informative components provide details that help organizations get started in thinking about how to approach the required and expected components. Sub-practices, example work products, notes, examples, and references are all informative model components.
信息组件提供了细节来帮助组织达到需求和期望部分。子实践。举例工作产品。日志，举例和引用 是信息组件的内容。
