Project Motivation • We are not adequately serving users who want to
compare, select, and access data from our catalog well, as evidenced by: § NASA ACSI feedback § UWG feedback § Requests to USO for data selection assistance § ESDIS-contracted Blink usability study
• We now have the metadata and system infrastructure necessary to make a dramatic improvements to the data selection workflow

Where we are
• Have implemented and improved all major functionality of the current Search § This is not the fully-realized Search § It sets the stage for the dramatic improvements
• We have performed intensive in-house testing • We are looking for feedback on the usability of
the current functionality

Usability Testing
“The extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use.” ~ISO 924-11
• Usability testing provides a qualitative method of gathering feedback from users about: § Effectiveness - can users do what they want to do? § Efficiency – is the amount of effort required in line with
expectations? § Satisfaction – how do users feel about their experience?
• Usability tests are conducted by watching users conduct a set of relevant tasks. Users are asked to verbalize their thoughts throughout the process.
