Accessibility Principles Global Supplier Assurance (GSA)

15 June 2015 Version 1.0


Principles – Background and Approach  As part of the Business Disability Forum – Technology Taskforce, Barclays has committed to support the Procurement Protocol, which states – ‘We will require, help and encourage our ICT supply partners to develop and deliver accessible products and services. We will formally consider accessibility in all our procurement decisions. We will purchase solutions which are as accessible as possible…In all purchasing decisions, it will be mandatory to formally consider the accessibility of any ICT product, service or system, together with the processes they enable.’  To meet the protocol, as well as our commitment to be the most accessible ‘Go-To’ bank, we must build accessibility into the sourcing and supplier management processes and create an environment for continual improvement. At Barclays we have implemented the following:

The existing Barclays Supplier Code of Conduct (CoC) includes a section on accessibility and suppliers are asked to self-certify their compliance on an annual basis.

Accessibility requirements are included in all relevant specification documents and specifically considered as part of the contract award decision process.

Barclays requires that suppliers adhere to the principles and related standards listed in this document.

Principles – Background and Approach Our accessibility principles:  ICT Accessibility is about ensuring that our internet sites and systems are easy to see, hear, understand, navigate and interact with, regardless of a user’s age, abilities, disabilities or circumstances. The foundation of the Web Content Accessibility Guidelines 2.0 (the basis for the Barclays Standards) lies upon four guiding principles or characteristics of accessibility. To summarize, an accessible system is Perceivable, Operable, Understandable and Robust (POUR). Implementing the POUR principles places our customers, colleagues, and clients, at the center of what we are creating. Accessibility is more than simply an application of technical requirements; it is very much about the human factor. The subsequent slides provide a high level overview of accessibility requirements through 12 principles and should be read first before referring to the more detailed, comprehensive and technical documentation on accessibility standards. Our standards:  Our accessibility standards have been developed to ensure new systems and enhancements to systems developed by and for the Barclays Group are made accessible to all customers and colleagues. These systems are now publically available to suppliers via our extranet. They are based on industry-wide accessibility standards and guidelines such as the W3C guidelines for web content (WCAG 2.0 AA) and application guidelines (desktop and mobile), along with specific criteria related to Barclays systems, recommendations made by recognised accessibility charities as well as manufacturer accessibility guidelines. To better understand the importance of and need for accessibility at Barclays, its benefits and why we encourage other organisations and suppliers to become more accessible, read our research on the accessibility business case. 3 | Accessibility Principles | 01/06/2015 Unrestricted

Accessibility Principles 1 – 4 of 12 Accessibility Principle


Why this is important

1. Perceivable non-text information

Text alternatives are provided for all non-text content such as images, charts and graphs. Labels are associated programmatically with interface objects.

If this principle is not implemented, any user who cannot see well enough to read the text or make out the graphics will not be able to perceive the information it contains.

2. Perceivable video and audio information

Captions and transcripts are provided for audio and video content.

If this principle is not implemented, users who cannot hear well enough will not be able to understand the information being given. If audio output is used to alert the user to an incident, users who cannot hear the alert will not know the incident has occurred.

3. Perceivable structure and presentation

Content is adaptable and made available to assistive technologies (“AT”). Users have access to the operating system accessibility tools, without affecting application functionality and any page titles, headings, forms and tables are clearly communicated via AT.

If this principle is not implemented, the structure and information cannot be determined by the AT, and therefore cannot be rendered in other formats as needed by the user.

4. Perceivable and distinguishable information

Sufficient contrast is used to make things easy to see and hear and colour is not relied upon to provide meaning.

If this principle is not implemented, the information conveyed through colour differences may not be seen by users with colour vision deficiencies. For audio screen reading software can find it hard to hear the speech output if there is other audio playing at the same time.

Accessibility Principles 5 – 7 of 12 Accessibility Principle


Why this is important

5. Operable functionality via multiple input methods

All content can be accessed without the use of a pointing device or pointing gestures in a logical way, shortcuts are provided to allow users to skip over large amounts of navigation or to complete common tasks, and keyboard focus and text cursors are clearly visible.

If this principle is not implemented, some users will be unable to use functions in the application/website. Users with limited motor control or hand tremors may be unable to control a pointing device accurately enough to target small objects. Some users may be impaired to the point that they can only operate a computer via a single two position switch.

6. Operable timeouts

Sufficient time is allowed to accommodate the slowest users by warning users and allowing them to either adjust, extend or turn off time limits.

If this principle is not adhered to, users with disabilities such as blindness, low vision, dexterity impairments and cognitive limitations, who require more time to read content or to perform functions such as filling out on-line forms, may be unable to do so. If functions are time-dependent, it will be difficult for some users to perform the required action before a time limit occurs.

7. Operable without causing seizures

The type of animated content used does not cause seizures. All forms of flickering and blinking are avoided.

If this principle is not implemented, items that change or move on a page can completely prevent some users from concentrating on the important information. Strobing, blinking, flashing and flickering can cause seizures in sensitive users (e.g. users with photo-sensitive epilepsy).

Accessibility Principles 8 – 10 of 12 Accessibility Principle


Why this is important

8. Operable navigation

Help users navigate and find content. Design and navigation is clear and consistent. Users should be able to confidently predict where interface elements can be found. Buttons, form controls, touch areas and links are large enough to be selected without the possibility of selecting adjacent controls. Multiple methods of reaching content are provided.

If this principle is not implemented, many users with reduced dexterity in their hands will find it difficult to operate because they either cannot accurately target the small controls or because uncontrolled movements cause their hands to stray off them. For users with cognitive impairments, inconsistent navigation can be confusing as they have to learn and remember a new navigation for each page or section.

9. Understandable content

Make text readable and understandable by using a clear typeface (non-serif i.e. Verdana) on a plain background. Use the simplest language possible for information, instructions, prompts and outputs.

If this principle is not implemented, users who are blind, partially sighted or have colour vision deficiencies may be unable to perceive all of the information that is presented in text and graphics. Users with reading impairments will experience difficulty comprehending and interpreting written language.

10. Understandable and predictable behaviour

Make content appear and operate in predictable ways. When content updates dynamically (i.e. without a page refresh), screen readers may not be aware. These functions can easily be made accessible. Options include ARIA roles and alerts, as well as front-end development frameworks that specifically support accessibility.

If this principle is not implemented, for any object on the screen, users may be unable to identify what it is, what it is for, what state it is currently in and how to operate it.

Accessibility Principles 11 – 12 of 12 Accessibility Principle


Why this is important

11. Understandable forms and instructions

Help users avoid and correct mistakes. If certain form fields are required, the field should be labelled accordingly, and configured to alert the screen reader user. After submitting the form, users will need to be alerted to submission confirmation and any submission errors and be given an easy way to navigate to those errors and correct them.

If this principle is not implemented, users with some impairments will have more difficulty creating error-free input. In addition, it may be harder for them to detect that they have made an error. Typical error indication methods may not be obvious to them because of a limited field of view, limited colour perception, or use of AT.

12. Compatibility with assistive technologies (Robust)

Maximise compatibility with current and future technologies. Descriptions and instructions for all accessibility features are provided.

If this principle is not implemented, the solution will not behave in a predictable way to users of AT. It is important that content follow conventions and be compatible with APIs so that AT can more easily work with new technologies as they evolve.
