CH5 Designing the Product: Framework and Refinement

Creating the Design Framework The design framework defines the overall structure of the users’ experience. 
Defining the interaction framework 
Define form factor, posture, and input methods（决定平台及明确他们各自的限制与要求） 
Define functional and data elements（决定数据的种类及承载它们的框架） 
Determine functional groups and hierarchy（决定功能和视图，归纳整理各个功能的位置） 
Sketch the interaction framework（决定粗略的设计框架） 
Construct key path scenarios（决定主要用户路径 - 以任务为主） 
Check designs with validation scenarios 
Alternative scenarios（其他case - 区别于主要用户路径的其他用户操作） 
Necessary-use scenarios（必要但少见的case） 
Edge-case use scenarios（极端case） 
Defining the visual design framework 
Develop experience attributes（确定产品的特性 - 形容词来形容他的feel，务必要具体，并且考虑竞品的特色及公司的branding） 
Develop visual language studies（确定视觉样式，充分考虑用户体验） 
Apply the chosen visual style to the screen archetype 
Defining the industrial design framework 
Collaborate with interaction designers about form factor and input methods 
Develop rough prototypes 
Develop form language studies 
Defining the service design framework 
Describe customer journeys 
Create a service blueprint 
Create experience prototypes 
Refining the Form and Behavior 
Validating and Testing the Design 
Usability testing is, at its core, a means to evaluate, not create 
Usability testing is not user research 
Summative evaluation - used in product comparisons, to identify problems prior to a redesign 
Formative evaluation - conducted during the design process
