Chapter 2: The Process of Interaction Design (c2 (The Double Diamond…

- - - - It is a process:
        
        Focused on discovering requirements, designing to fulfil requirements, producing prototypes and evaluating them
        
        Focused on users and their goals
        
        Involves trade-offs to balance conflicting requirements
      - Generating alternatives and choosing between them is key
      - Four approaches: user-centered design, activity-centered design, systems design, and genius design
  - - - Phase 3: Developing possible solutions.
      - Phase 4: Delivering the solution.
    - - Phase one: Discovering the problem.
      - Phase two: Defining the problem.
- - - - Full time: constant input, but lose touch with users
      - Part time: patchy input, and very stressful
      - Short term: inconsistent across project life
      - Long term: consistent, but lose touch with users
    - - Crowdsourcing design ideas
      - Citizen science
      - Online Feedback Exchange (OFE) systems
- - - - Team effort
      - Explore different perspectives
      - Avoid incorrect assumptions and unsupported claims
- - - - – those who interact directly with the product
      - – those who manage direct users
      - – those who receive output from the product
      - – those who make the purchasing decision
      - – those who use competitor’s products
    - - Larger than the group of direct users
      - Identifying stakeholders helps identify groups to include in interaction design activities
- - - - – their context
      - – what information do they require?
      - – who collaborates to achieve the task?
      - – why is the task achieved the way it is?
    - - – can be described as future scenarios
      - – can be rooted in existing behaviour
