I) Discover
The first stage is focused on understanding user needs through research and feedback. Here, designers gauge what the experience is now, define the problem and lay the groundwork for new ideas and user-centred solutions.
Make accessible by:
- Intentionally seeking different perspectives by involving a diverse range of users via nontraditional recruitment methods, with appropriate compensation.
- Gathering insights through multiple channels so people with disabilities or technological needs can access them.
- Using clear, inclusive language in all communications to avoid any groups feeling unseen and, thus, unmotivated to participate.
II) Define
Insights gathered during discovery will help clearly articulate the core problem or challenge at hand. Here designers analyze the findings, determine key themes, and create a specific problem statement to guide design and development efforts.
Make accessible by:
- Involving diverse users to co-create the problem statement, validating it against their experiences and needs.
- Using easy-to-understand visual aids during in-person sessions to help convey complex ideas.
- Use feedback loops to capture insights in different ways to collectively refine and ultimately define the problem statement.
When reviewing design, engage quality assurance engineers to conduct accessibility audits to catch potential issues before development begins.
III) Develop
The second diamond concentrates on the approach — all ideas are on the table when it comes to answering that defined problem. Here, teams collaborate to generate and refine those ideas through prototyping and iterative testing, collecting user feedback and adjusting as necessary. This phase ends with a tailored, sturdy solution that meets user needs.
Make accessible by:
- Using inclusive design frameworks.
- Taking time to deliberate on implicit bias by interrogating your assumptions so you don’t accidentally leave any groups out.
- Absorbing unique insights from people with various backgrounds and abilities, making for more innovative and inclusive products.
- Creating low-cost, low-fidelity prototypes that can be easily modified based on user feedback.
- Detecting common issues through automated testing tools but prioritizing manual testing for nuanced usability concerns that AI may overlook.
- Test drive UX through various accessibility scenarios — such as vision, hearing, and cognitive or motor impairments — not just for compliance but ease of use and efficiency.
IV) Deliver
In the final stage, designers test different solutions at a small scale, rejecting those that won’t work and tweaking those that will. The chosen solution is finalized and, before it is launched, a final round of testing ensures it meets user requirements and business goals. Its performance is monitored as it rolls out.
Make accessible by:
- Making your final product accessible to all users by adhering to top standards (e.g., WCAG, ADA, ACA).
- Providing accessible training and support to broaden inclusivity and supporting all users to engage effectively.
- Supporting users to give ongoing feedback through accessible channels.
- Considering the widest range of user scenarios to identify potential barriers and reducing risks of exclusion early.
- Creating a transparent “accessibility debt” tracking system that allows users to help prioritize improvements from that backlog.
- Using manual testing for accessibility with screen readers (JAWS, NVDA, VoiceOver) and keyboard-only navigation, which can snuff out real-world usability issues.
