USABLE-1. USABILITY PRACTICES

Entities conducting digital identity management functions MUST apply user-centric design, and industry-accepted appropriate usability guidelines and practices, to the communications, interfaces, policies, data transactions, and end-to-end processes they offer, and remediate significant defects identified by their usability assessment.

SUPPLEMENTAL GUIDANCE

All user experience in a digital identity management role will conform to this requirement and other USABLE requirements.

The term "user-centric" design is a key tenet and requirement of the IDESG founding document: the National Strategy for Trusted Identities in Cyberspace (NSTIC) dated April 15, 2011. This term is further described in Appendix A and is a common term in the User Experience domain.

The term “user-centric” permeates the NSTIC Strategy (now stored at: https://obamawhitehouse.archives.gov/sites/default/files/rss_viewer/NSTICstrategy_041511.pdf) and the IDESG principles, dated April 15, 2011. This term is further described in Appendix A and is a common term in the User Experience domain. Besides those items related to security, privacy and interoperability, these UX items are part of the strategy:

• Transparency, the user understands the data collected and how it will be used
• Reduced Cognitive Load on the User, minimize the number of authentication factors, like passwords.
• Easy to Use by automating the user’s ability to know and change data held about them.
• Improve confidence by showing users that web sites are part of a trusted framework.
• Choice to present alternative identifiers or authentication servers to authorize access.
