必须定义切实可行的SLA，以塑造FSB的整合性和可用性，因为这是迭代中的工作。
A feasible SLA must be defined for build integration and availability of FSB, as this becomes the duration of an Iteration.
另外，有效地评估可用性的方法也能帮上不少忙。在本文中，我将定义并且着重讨论可用性的四个层面：易学性，简洁，效率，以及美感 [1] 。
It is also helpful to have concrete methods for analyzing usability, and in this article I'll define and focus four dimensions of usability: Learnability, Simplicity, Efficiency, and Aesthetic [1].
按照其定义，此类核心组也视为特定服务的高可用性域。
