规则是关于在应用程序中执行活动的规定性程序集
企业规则存在于企业中，无论它们是否被写下来，
谈论，甚至是组织意识的一部分。然而，这是相当普遍的
组织为特定目的以正式方式收集规则的实践。
业务规则是一种控制操作的规则，最初作为
项目初始阶段或活动期间的正式需求收集过程
分析或事件分析。在这种情况下，收集业务规则与
确定流程工作流的更大发现过程。项目，如
启动支持新的或更改的业务操作的新系统或服务
可能会为需要员工的组织带来一套新的业务规则
以新的方式概念化组织的宗旨。这种做法是巧合
业务规则收集容易产生不一致甚至冲突的数据
不同组织单位或同一组织单位内的业务规则
随着时间的推移。
DoDAF元模型提供了一组关于规则的清晰、简洁的数据，有助于
创建规则，并允许与需要类似规则的其他人共享这些规则
信息
规则不是一个过程-这两者虽然相关，但却非常不同。过程是
从现有事物（输入）产生新事物（输出）的转换，而规则
规定了用于确保输出符合预期的准确程序
执行该过程的每个实例。

关于规则数据组，应注意以下事项：
a、 规则约束活动。例如，限速规则限制驾驶活动。
一些看似静态的规则具有限制可能活动的效果。对于
例如，安全围栏必须为10英尺高的规则限制了
建筑安全围栏。在某些条件下，该约束可能适用或变化。
例如，在恶劣天气条件下，速度限制可能较低。
b、 安全分类、安全标记、可发布性等是指南的类型。
类似地；规则是一种更强的指导形式。
c、 一个重要的约束类型是服务策略，它约束对能力的访问
表演者。
d、 根据定义，条令限制了军事行动。
核心流程中的使用
规则数据用于创建、记录和共享支持的所有类型的规则
运营活动和/或运营过程中能力的执行（复合
活动）。这些数据可以包括：
a、 定义必须交换或传递数据的事务的流程
执行***的活动，如PPBE、CPM、JCIDS或DAS。
b、 定义访问网络中心内信息或服务的方法的规则

Rules are prescriptive sets of procedures regarding the execution of activities within an
enterprise. Rules exist within the enterprise whether or not they are ever written down,
talked about, or even part of an organization&＃39;s consciousness. However, it is fairly common
practice for organizations to gather rules in a formal manner for specific purposes.
Business rules are a type of Rule that govern actions and are initially discovered as part of a
formal requirement-gathering process during the initial stages of a Project or during activity
analysis, or event analysis. In this case, the collecting of the business rules is coincidental to
the larger discovery process of determining the workflow of a process. Projects such as the
launching of a new system or service that supports a new or changed business operation
might lead to a new body of business rules for an organization that would require employees
to conceptualize the purpose of the organization in a new way. This practice of coincidental
business rule gathering is vulnerable to the creation of inconsistent or even conflicting
business rules within different organizational units, or within the same organizational unit
over time.
The DoDAF Meta Model provides a set of clear, concise data about rules that facilitates the
creation of rules and enables the sharing of those rules with others requiring similar
information.
A rule is not a process - the two, while related, are very different. A process is a
transformation that produces new things (outputs) from existing things (inputs), while a rule
prescribes the exact procedures to be used to ensure that the output is as to be expected in
each instance that the process is executed.

DoDAF Meta Model for Rules
(Click image to enlarge)
The following should be noted about the Rules Data Group:
a. A Rule constrains Activities. For example, a speed limit rule constrains driving activity.
Some seemingly static rules have the effect of limiting possible activities. For
example, a rule that security fences must be 10 feet high constrains the activity of
building security fences. This constraint may apply or vary under certain conditions.
For example, speed limits can be lower in poor weather conditions.
b. Security classification, security marking, releasability, etc. are types of Guidance.
Similarly; a Rule is a stronger form of Guidance.
c. An important Constraint type is a Service Policy that constrains access to capability
Performers.
d. Doctrine, by definition, constrains military action.
Usage in Core Processes
Rules data are used to create, document, and share rules of all types that support
operational activities and/or the execution of capabilities in operational processes (composite
activities). These data can include:
a. Processes that define transactions where data must be exchanged or passed to
execute a specified activity, such as PPBE, CPM, JCIDS, or DAS.
b. Rules that define methods of accessing information or services within the net-centric
