Evaluation

• The process of systematically collecting data
  that informs us about what it is like for a
  particular or group of users to use a product for
  a particular task in a certain type of environment

Design should progress in iterative cycles of
design-evaluate-redesignSave moneySave time
5
Iterative design, with its repeating cycle of
design and testing, is the only validated
methodology in existence that will consistently
produce successful results. If you dont have
user testing as an integral part of your design
process you are going to throw buckets of money
down the drain- Tognazzini (Usability
Consultant)

Some good reasons

• Problems are fixed before product is shipped, not
  after.
• The team can concentrate on real problems, not
  imaginary ones.
• Engineers code instead of debating.
• Time to market is sharply reduced.
• Good product design that works for sales pitches.
