- ▪ 各个组件可能是由不同的个人或小组设计的。组件之间存在着确定或不确定的相互作用关 系，所以各个小组要协调他们的设计，交流各自的信息。为了更好地管理这种协作过程，开发人员应该在系统设计阶段明确组件之间那些已知的相互作用。 - ▪ 各个组件可能是由不同的个人或小组设计的。组件之间存在着确定或不确定的相互作用关 系，所以各个小组要协调他们的设计，交流各自的信息。为了更好地管理这种协作过程，开发人员应该在系统设计阶段明确组件之间那些已知的相互作用。

- 首先是基本的相互作用关系 (fundamental interaction), 它与 示意图中连接各组件的那些线条相对应。例如， 一张纸从纸张托盘移动到打印装置中，因为 这种基本的相互作用关系是系统运行的基础，所以，在最早设计示意图时就应该计划好，并 要很好地加以理解。其次是附属的相互作用关系 (incidental interaction), 它是功能单元特定的 实体设置或组件之间具体的几何排列造成的。例如，纸张托盘中的传动器所引起的震动会干 扰打印墨盒在X 轴的精确定位。 It is most likely that a different person or group will be assigned to design each chunk ¡ Because the chunks interact with one another in both planned and unintended ways, these different groups will have to coordinate their activities and exchange information ¡ To manage this coordination process better, the team should identify the known interactions between chunks during the system-level design phase There are two categories of interaction l Fundamental ¡ Those which correspond to the lines on the schematic that connect the chunks to one another ¡ These are the fundamental interactions of the systems operation l Incidental ¡ Those that arise because of l the particular physical implementation of functional elements, or l because of the geometric arrangement of the chunks ¡ An incidental interaction graph is used to document this type of interaction, see next slide - 首先是基本的相互作用关系 (fundamental interaction), 它与 示意图中连接各组件的那些线条相对应。例如， 一张纸从纸张托盘移动到打印装置中，因为 这种基本的相互作用关系是系统运行的基础，所以，在最早设计示意图时就应该计划好，并 要很好地加以理解。其次是附属的相互作用关系 (incidental interaction), 它是功能单元特定的 实体设置或组件之间具体的几何排列造成的。例如，纸张托盘中的传动器所引起的震动会干 扰打印墨盒在X 轴的精确定位。 It is most likely that a different person or group will be assigned to design each chunk ¡ Because the chunks interact with one another in both planned and unintended ways, these different groups will have to coordinate their activities and exchange information ¡ To manage this coordination process better, the team should identify the known interactions between chunks during the system-level design phase There are two categories of interaction l Fundamental ¡ Those which correspond to the lines on the schematic that connect the chunks to one another ¡ These are the fundamental interactions of the systems operation l Incidental ¡ Those that arise because of l the particular physical implementation of functional elements, or l because of the geometric arrangement of the chunks ¡ An incidental interaction graph is used to document this type of interaction, see next slide
