UX Usability Requirements and Guidelines Working Document

Overall mission of UXC requirements: Human users shall be able to understand the need for any personal information and be enabled to supply it with the least disruption to their work flow at the service provider site.

NOTE: the Requirements in bold reflect what was revised and turned into the FMO in June, 2015 for the combined requirements across all groups and committees. Below each requirement there is supplemental information and links about each HLReq. In addition, we have created a UXC Dictionary page.

1) HL Requirement, USABLE-1: 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. (Category: Usable language)

• Consult the UXC Resources page located here for examples of non-normative UX practices: https://www.idecosystem.org/wiki/UXC_resources

• Consult the UXC Dictionary page located here for examples of UXC definitions of terms in these requirements and supplemental guidelines: https://www.idecosystem.org/wiki/UXC_Dictionary

• The term "user-centric" design comes from the IDESG founding document: the National Strategy for Trusted Identities in Cyberspace dated April 15, 2011. This term is further described in the UXC Dictionary and exists in a common semantic domain.

2) HL Requirement, USABLE-2: Entities MUST assess the usability of the communications, interfaces, policies, data transactions, and end-to-end processes they conduct in digital identity management functions.

• Consult the UXC Guidelines and Metrics page: https://www.idecosystem.org/wiki/User_Experience_Guidelines_Metrics

3) HL Requirement, USABLE-3: Information presented to USERS in digital identity management functions MUST be in plain language that is clear and easy for a general audience or the transaction's identified target audience to understand. (Category: Clarity of pathways, options, solutions)

• Instructions for use of the system should be visible or easily retrievable whenever appropriate.  :• Help and documentation information should be easy to search, focused on the users' task, listing concrete steps to be carried out, and be concise.

• Platform conventions for words, actions, and situations are consistent across the platform.

       o Example: Users should not have to wonder whether different words, situations, or actions mean the same thing across the platform.

• The system should speak the users' language, following real-world conventions and making information appear in a natural and logical order.

       o Example: Systems should use words or phrases and graphics or icons familiar to the user rather than system-oriented terms.
       o Example: "privacy enhancing technology" - research shows that "privacy protection" is the preferred term by real users.                            

• Error messages should be expressed in plain language, without codes, clearly indicating the problem and constructively suggesting a solution.

• The user’s identity status on a system should be clear to the user.

       o Example: It should be clear to the user whether their identity is anonymous, pseudonymous or verified.

• Any change in identity status should be presented in clear language to the user.

       o Example: If a process requires a user to switch to a verified identity from a more anonymous state, the user should be clearly prompted to change their identity status.

• Descriptions of states of identity (verified, anonymous, pseudonymous) should be linked to clear, easy to read, understandable and concise definitions.

• If standard definitions are available, they should be used.

• The design of the website should eliminate information that is irrelevant or rarely needed.

• Layout and look/feel/branding, in addition to language, should also eliminate information that is rarely needed.

4) HL Requirement, USABLE-4: All choices, pathways, interfaces, and offerings provided to USERS in digital identity management functions MUST be clearly identifiable by the USER. (Category: Accessibility for all)

• Organizations should operate in a manner that allows individuals to easily switch service providers if the organization fails to meet user expectations, becomes insolvent, is incapable of adhering to policies, or revises their terms of service. (V2)

• Systems should provide clear and easy to use pathways to help users recognize, diagnose, and recover from user-made errors.

• The information needed by the user to understand any choice should be clearly visible in a single, visible window. Dialogues should not contain information that is irrelevant or rarely needed.

• To mitigate the risk of errors, systems should allow the user the option to cancel, skip or decline, before they commit to a pathway action as well as provide a confirmation notice after they commit.

• If an entity decides an action is required, and a user chooses to skip or decline this action, the Entity's system should state clearly to the user if the transaction will not be completed.

• If a user accepts, skips or declines an option, the Entity's system should state clearly to the user the transaction was or was not completed.

• Entity's systems should allow users the choice to proceed anonymously, pseudonymously or with any chosen / assigned identity where appropriate.

• Entity's systems should allow the user choice and clear options for changing the status of their identity. For example: switching to anonymous browsing.

• Information users need to make decisions should be readily available and transparent to the user.

• The identity of the Entity and Entity's systems with which the user is interacting should be clearly visible and understandable to users at all times. This includes third parties and changes between Entities and users during sessions.

• When a new user chooses an identity provider, the available options should be clearly presented so that a user can make an informed decision. When a new user visits a Relying Party site, the user should be presented with information about the request for identity proofing, verification or attributes and the types of identity providers or frameworks that are acceptable.
 :• Clear pathways should exist for users to procure desired services.

• The user should be presented with pathways to the identity service they desire, such as: privacy options, identity caching, etc.

5) HL Requirement, USABLE-5: All digital identity management functions MUST make reasonable accommodations to be accessible to as many USERS as is feasible, and MUST comply with all applicable laws and regulations on accessibility. (Category: Response to user feedback)

• Entities should review all accessibility standards and apply what they deem feasible to their sites based upon their legal and regulatory environment.

• All Entities, when feasible, should provide equivalent access to and use of information and systems to users with disabilities that is comparable to the use and access by those who are users without disabilities.

• All IDESG compliant sites must provide all feasible functionality to any user with a compatible internet connected device as those available to individuals without disabilities.

• Users with disabilities should have access to documentation tailored to their needs, as is feasible.

• User Centered Design that accounts for accessibility issues must be used whenever possible.

• Additional industry requirements, should when feasible be reviewed and used. They include but aren't limited to health, finance, universal accessibility, etc.

• Some existing standards and regulations include:

• Section 508 contains information about accessibility. https://www.section508.gov/

• ISO: TBD

6) HL Requirement, USABLE-6: All communications, interfaces, policies, data transactions, and end-to-end processes provided in digital identity management functions MUST offer a mechanism to easily collect USERS' feedback on usability.

• All IDESG compliant sites should provide a mechanism to gather feedback from users on site usability, adjusting the site design in response when appropriate.

• Users should be provided equitable choices around the mechanisms they can use to express their feedback to entities. Parameters, risks and benefits for those choices should be clear to the user.

• Additional information on collecting user feedback can be found in our UXC Guidelines and Metrics page: https://www.idecosystem.org/wiki/User_Experience_Guidelines_Metrics

7) HL Requirement, USABLE-7: Wherever public open STANDARDS or legal requirements exist for collecting user requirements, entities conducting digital identity management functions MUST offer structured opportunities for USERS to document and express their interface and accessibility requirements, early in their interactions with those functions. Entities MUST provide a response to those user requirement communications on a reasonably timely basis.

• Any entity "collecting personal data," whether they are first or third parties, would mean that the entity is interacting with users directly and therefore should provide a response to user requests early on in the interaction or collection.  :• As a general principle, consent choices or other similar must-see-this-first information should be exchanged in a first encounter, and then honored in and presented in a consistent manner thereafter.

• Suggested ways for User Experience mitigation includes using pop-up boxes or email responses to user requirement communications. Links to information regarding additional use should provide adequate time for users to read the information presented to them.

• The entity gathering information should state whether identity information is being used, and the user must be notified.

USABLE-BP-A. RECOMMENDED ATTRIBUTE REQUIREMENTS QUERY Entities conducting digital identity management functions SHOULD offer persistent opportunities for USERS to document and communicate their unique requirements about their attributes and how they are used. Entities SHOULD provide good-faith responses to those communications about requirements, before the USER is asked to agree to share their attributes.

• As a general principle, consent choices or other similar must-see-this-first information should be exchanged in a first encounter, and then honored in and presented in a consistent manner thereafter.

• Suggested ways for User Experience mitigation include pop-up boxes or email responses to requests. Links to information for additional use and adequate time to read should be included in the process for end users.

• Entities must state clearly in an easy to find manner to users whether identity information is being used.

• Special attention must be paid to the unique dynamics and vulnerabilities for users around attribute exchanges, particularly toward transparency of communications.
