传播项目模型变更到执行者流程
从企业模型那里传播项目模型。
获取到项目模型的执行者模型。
从企业模型中获取项目模型。
这就需要另一步：从企业模型中传播变更到项目模型中。
That requires another step: propagation of changes to the project models from the enterprise models.
获取项目模型到企业模型：从项目到企业模型获取变更。
Harvest project models to enterprise models: Harvest changes from a project to the enterprise model.
在定义上，项目模型与企业模型总是存在一定程度的差异性。
By definition, project models are always somewhat at variance with the enterprise models.
对于每一个处理项目模型的个人来说，必须要有一个私人流程。
There must be a private stream for every individual who works on the project models in any capacity.
企业模型和项目模型之间的互动驱动了本文中记录的许多规程。
The interplay between enterprise models and project models drives many of the procedures documented in this article.
例如，有一种政策规定只有项目模型管理员会执行获取和传播操作。
An example of this is a policy that only the project model manager may perform harvest and propagate operations.
项目模型管理员可能希望执行自己的模型管理任务，如图12所示。
Project model Managers would be expected to perform model management tasks on their behalf, as shown in Figure 12.
在企业层次里，变更可以从获得的范例模型发布，并从项目模型获取。
At the enterprise level, changes can be propagated from the acquired exemplar models and harvested from the project models.
这就需要另一步：从企业模型中传播变更到项目模型中。 。
That requires another step: propagation of changes to the project models from the enterprisemodels.
在最新的企业模型和最新的项目模型之间，可能会有冲突性的变更发生。
There may be conflicting changes between the latest enterprise models and the latest project models.
项目模型管理员可能期望代表这种没有多少技术含量来执行这些例行程序。
The Project Model Manager might be expected to perform these procedures on behalf of those less technically inclined.
本段解释了要么是项目模型管理员要么是数据建模人员执行的存储库操作。
This section explains the repository operations that either the Project model Manager or a software or data modeler will perform.
模型管理政策需要在模型层中应用，例如，在企业和项目模型流之间应用。
Model governance policies need to be applied at model layer boundaries, for example, between the enterprise and project model streams.
所有这些变更会成为企业模型的一部分，或者在某个时段从项目模型中删除。
All such changes are intended to become a part of the enterprise models or to be removed from the project models at some point.
项目模型：该层包含了源自企业模型的模型，并含有暂时性的差异。
Project models: This layer contains models that descend from the enterprise models and contain transient differences.
如果模型管理员需要的话，这些变更可以进一步传播到其他所有的项目模型中。
These changes can be further propagated to all other project models if desired by the model managers.
从企业模型中播种项目模型：创建项目流程并将它们发布到企业模型的最新版本。
Seed project models from enterprise models: Create project streams and seed them with the latest version of the enterprise models.a.
例如，每周一上班工作开始的时候，将项目模型的新版本传播给每一个项目执行者。
For example, weekly at the start of business on Monday, the new version of the project model is propagated to each of the project's practitioners.
与之类似的是，重要项目模型的采用可能会激发所有其他项目间相同类型的最终发布。
Similarly, the adoption of important project model changes may trigger the same type of eventual propagation throughout all other projects.
项目模型是怎样升级这些变更的(意思：与企业模型的最新推荐版本保持同步化)？
How do the project models get updated with those changes (meaning: become synchronized with the latest recommended version of the enterprise models)?
另一层意思是这些新的版本必须成为企业模型，所有项目模型，所有操作模型的新父类。
Another implication is that these new versions must become the new parents of the enterprise models, all project models, and all practitioner models.
在项目模型管理员创建后续流程以作为业务分析员使用的代理时，注意这个方案并不会变更。
Notice that this scenario does not change when the descendant stream is created by the Project Model Manager as a proxy for the use of a Business Analyst.
新的特性会立即向所有其他项目模型传播，此时企业中的所有模型将会达到一种完美的排列。
The new features would be propagated immediately to all other project models, and all models in the enterprise would come into perfect alignment at that moment.
当然项目模型管理员选择重构未接受的模型变更，删除它，或者为稍后再次的获取拒绝变更。
The project model manager may, of course, choose to re-factor the unaccepted model change, to remove it, or to bring the rejected change forward for harvesting again later.
回到图3，范例模型，企业模型和项目模型按照以下方式相关，起始向下流至后代。
Recalling Figure 3 again, Exemplar models, Enterprise models and Project models are related as follows, with ancestors flowing downward to descendents.
DARPA还想研究项目模型，允许开发者在安全性、可靠性、功效和性能方面更轻松地设计。
DARPA also wants to study programming models that allow developers to more easily design in security, dependability, power efficiency and high performance.
