360 degrees of usability

ABSTRACT

Global usability testing and gathering ongoing user feedback from initial concept through post launch was critical to the project success. Several different methodologies were deployed during the process. During pre launch, surveys were used to gather high-level feature preference assessments; live baseline usability testing determined areas of the flow that were difficult for users to comprehend and complete. Data from the surveys and baseline usability tests was incorporated into the redesign of the feature and page flow. Iterative prototype testing of the redesign focused on identifying major usability issues and updating the design after each round of testing to solidify and finalize the design direction. Community involvement using regular focus groups and a live, interactive preview helped inform the community and soften reaction to the change. During post launch, community feedback was leveraged to gather feedback on feature enhancements while additional rounds of iterative prototype testing tested the flow efficacy. The enhancements were presented to focus groups to ensure community needs were addressed, thus completing the usability feedback loop.
