    • Why Consistency is Gooood
      • Less cognitive efforts on learning your App
      • Less cognitive resources wasted
      • Increased positive user experience
      • Happy users!
      • Users are more likely to come back
      • Users will spend more time ‘exploring’ your App
    • Two Types of Consistencies
      • Internal Consistency - Within you App
        • Two identical elements have the same behaviors and consequences
        • Internal knowledge within the App
      • External Consistency - Without you App
        • Elements in your App follow the ‘conventional’ user interface norms
        • Internal knowledge of the App in comparison to the external knowledge
        • Forward Transfer
    • Internal Consistency
      • When two identical elements have the same behaviors and consequences
      • Internal knowledge within the App
      • Limited user cognitive resources is spent
        • Learning processes minimized
      • Users more willing to explore your App
        • You are using what users already know
        • Predictable and learnable Apps
        • More cognitive resources is spent on exploring your App, as opposed to learning at the element levels
      • Happy users who keep consistently coming back!
      • NOTE: More important to implement Internal rather than External Consistency
    • Consistent Internal Behavior
      • Customization
        • Google Chrome behaves the same even if the user is allowed to customize
    • No Internal Consistency?
      • Users will spend time and energy on learning, as opposed to exploring your App
      • Frustrated users
      • Higher percentage of users are likely to leave your App within amount of short time

    • External Consistency
      • To be consistent with the ‘conventional norms’
      • Forward Transfer
        • Sounds too dry and not as creative?
        • The reality is that users want to be able to recognize various element on your App
        • Users prefer to explore Apps rather than trying to learn them all over again
    • Icons… FOR EVER!!!
    • Identifying Areas Where You Can Be Consistent

      • It’s OK to make your own controls but don’t have them behave differently than the conventional existing controls

      • If something looks DIFFERENT, it should behave DIFFERENT
