Design: design methodology, prototyping, cybersecurity case study

Intro to Design

• Have the insight of the users who are they.
• To include children or not.
• Testing your design with users.
• Involving the users from the very start of your design.
• What other people are doing in your niche, and you should probably design something similar for familiarity reasons of mental models
• Define your goal, is it an innovative idea, or something already existing but adding a value over it.
• Don’t wait until your product is finished, take input from the users from the very first stage of design.

Design Methodologies

Design Process

The Golden rule is;

• Know Your User.
• Where do ideas come from?
• Many processes;
  • Iterative design

• System centered design
  • What can be built easily on this platform?
  • What can I create from the available tools?
  • What do I as a programmer find interesting to work on?
• User centered design
  • Design is based upon a user’s
    • Abilities and real needs
    • Context
    • Work
    • Tasks
• Participatory design
  • Problem
    • intuitions wrong
    • interviews etc. not precise
    • designer cannot know the user sufficiently well to answer all issues that come up during the design
  • Solution
    • designers should have access to a pool of representative users. That is, END users, not their managers or union reps!
• Designer centered design

  “It’s not the consumers’ job to know what they want.”

  Steve Jobs

Case Study: SSL Warnings – example user

• User knows something bad is happening, but not what.
  • User has good general strategies (worry more about sites with sensitive info)
  • Error message relies on a lot of information users don’t understand
