Analysis of the communication event

• Some questions
• Product What exactly are you being asked to
  design?
• Users Who are the users? What do we know
  (would we like to know) about the users?
• Tasks What tasks will the users do with the
  product?
• Context What is the context in which these
  tasks will be carried out? Under what
  circumstances?
• Usability What usability considerations are
  relevant here?
• Your task Think pair share

8
Dimensions of Usability

• Definition
• The extent to which a product ca be used by
  specified users to achieve specified goals in a
  specified context of use with effectiveness,
  efficiency and satisfaction. ISO-9241-11
• From Nielsen
• Satisfaction, Learnability, Memorability, Errors,
  Efficiency
• Also
• Understandability, Scannability, Readability

9
Debriefing Sessions

• Presentations
• 5 minutes
• Same goals as the design rationale
• Q and A
• Remaining students will work in groups to ask
  questions relative to three pre-defined
  categories user advocacy, usability /
  effectiveness, software usage
• These groups will be formed on an adhoc basis
