Fundamental Design Tasks and Activities

Understanding the challenges in Iteration 0

Iteration 0 refers to the work done before incremental development begins.
迭代0是指增量开发开始之前完成的工作。

• This includes early product planning, getting the development team started up,setting up their physical and tooling environment, and making an initial architectural definition.
  这包括早期产品规划、启动开发团队、设置物理和工具环境以及制定初始架构定义。
• All of this work is preliminary and most of it is expected to evolve over time as the project proceeds.
  所有这些工作都是初步的，其中大部分工作预计将随着项目的进展而不断发展。

Structural Modeling and Behavior Modeling

A structural model is a formal way of representing the objects that are used and created by a business system
结构模型是表示业务系统使用和创建的对象的正式方式。

One of the primary purposes of behavioral models is to show how the underlying objects in a problem domain will work together to form a collaboration to support each of the use cases.

Sequence Diagrams：show object interactions arranged in time sequence,vertically
序列图：显示按时间顺序排列的对象交互，垂直

Communication Diagrams：show object interactions arranged as a flow of objects and their links to each other, numerically
通讯图：以数字方式显示排列为对象流的对象交互及其相互之间的链接

Design Thinking Fundamentals 设计思维基础

1. Human rule. All design is social in nature.

2. Ambiguity rule. Preserve ambiguity.

3. Redesign rule. All design is redesign.

4. Tangibility rule. Make ideas tangible to facilitate communication

5. 人治。所有设计本质上都是社会性的。
   2.歧义规则。保持歧义。
   3.重新设计规则。所有的设计都是重新设计。
   4.有形规则。让想法具体化以促进沟通。
