Prioritizing Remediation of Accessibility Issues

Join Karl Groves, Director of Training at Deque Systems, as he explores the intricacies of accessibility remediation. This session will cover fundamental concepts like defining accessibility issues, understanding risk, and the importance of prioritization in addressing accessibility challenges. Learn both simple and advanced prioritization methods, focusing on user impact, ease of repair, and how to manage remediation processes effectively. Participate in a collaborative discussion as we assess ways to maximize efficiency while ensuring higher accessibility standards.

  1. Prioritizing Remediation of Accessibility Issues

  2. About Me Karl Groves, Dir. of Training, Deque Systems karl.groves@deque.com @karlgroves 571-455-4862 Also, a rock star*

  3. Agenda • What is an accessibility issue? • Why prioritize? • Understanding risk • Challenges • Remediation Approaches • Considerations • Simple Prioritization • Advanced Prioritization

  4. Things to keep in mind • I am mathematically challenged • This topic is exploratory, not declarative • Please participate, ask questions, offer new ideas

  5. What is an accessibility issue?

  6. What is an Accessibility Issue? • Bug: Term used to describe an error, flaw, mistake, failure, or fault in a computer program or system that produces an incorrect or unexpected result, or causes it to behave in unintended ways.

  7. Why Prioritize?

  8. Why Prioritize? • Apply resources most effectively • Minimize accessibility’s impact on business • Motivate development staff • Maximize positive impact for users • Reduction of Risk

  9. Understanding Risk

  10. Understanding Risk • Risk is the potential that a chosen action or activity (including the choice of inaction) will lead to a loss (an undesirable outcome).

  11. Understanding Risk • Ultimately, remediation of bugs is an effort at risk mitigation • Risks of • Poor quality (Users having problem with system) • Lost income • Ancillary losses • Administrative Complaint (public sector) • Litigation

  12. Understanding Risk • Probability Probability = (number of negative events) / (population)

  13. Understanding Risk • Risk Amount Risk Amount = (probability of a negative event) * (expected loss in case of negative event)

  14. Understanding Risk • ROI ROI = ((Risk Amount - Investment)/ Investment)*100 Where: Risk Amount = Expected loss * probability Investment = Money spent on Accessibility

  15. What factors impact our ability to fix our system? Challenges

  16. Challenges • Not all accessibility problems are equal • Time • Impact • Impact on Users • Impact on Business • WCAG Level & SC is inappropriate for determining priority

  17. Challenges • Time • Often at a premium • Time spent on after-the-fact bug repairs is time that is taken away from meeting other business needs • See, “Technical Debt”, Martin Fowler

  18. Challenges • Impact • Budgets • Resources • System

  19. Remediation Approaches

  20. Simple Prioritization • Simple Prioritization • Focused solely on time and (simple) impact • How long will it take? • How bad is the problem?

  21. Simple Prioritization • Pros • Focused on the user • Super simple • Often, “hunch” from expert is as good as something more formal • Cons • Does not take into consideration impact on business or system

  22. Advanced Prioritization • User Impact • Ease & Speed • Impact on Interface • Volume • Location • Secondary Benefit • Each item ranked: None (0), Low (1), Medium (2), High (3)

  23. Advanced Prioritization • Impact on Users with Disabilities • Broken down by type of user & impact on each • IB - Blind • IV – Visually Impaired (non-blind) • IH – Deaf & HoH • IM – Motor • IC - Cognitive • IS – Speech • Impact* = (IB + IV + IH + IM + IC + IS)

  24. Advanced Prioritization • Ease and Speed of Repair

  25. Advanced Prioritization • Impact on Interface & Operation

  26. Advanced Prioritization • Volume of Repeat Issues • How many times does the exact same issue occur? • How many times do (very) similar issues occur?

  27. Advanced Prioritization • Location of Issues • Traffic • Criticality of location

  28. Advanced Prioritization • Secondary Benefit • Older Users • Low Literacy Users • Low Bandwidth Users • Reduced Dev/ Maintenance time • Alternate Devices • SEO • Usability • Tie to org goals

  29. Advanced Prioritization • (Impact + Repair Speed + Location + Secondary Benefits) * Volume = Priority • Sort all issues according to priority • Fix em!

  30. Advanced Prioritization • What’s missing? • Normalize data? • Do some of this ahead of time? • Importance ranking for each factor • Risk from Litigious user types?

  31. Dilution Managing Remediation

  32. Managing Remediation • You have a report full of bugs • Now what do you do?

  33. Managing Remediation • Managing Remediation is a process not unlike dilution in chemistry • Dilution: The process of reducing the concentration of a solute in solution • In our case: reducing concentration (defect density) in a system Concentration = numBugs/linesOfCode

  34. Managing Remediation Accessibility Errors - High Priority - Medium Priority - Low Priority Non-CompliantSystem Partially-CompliantSystem Mostly-CompliantSystem

  35. Managing Remediation Fully-Compliant System

  36. Managing Remediation • Measuring improvement (concentrationStart - concentrationEnd) / time Only 1st order accurate. Perfect for snapshots.

  37. Conclusion

  38. Conclusion • In the quest for #perfectA11y, prioritization helps us get closer quicker • We must maximize efficiency to have high positive impact • Multiple factors exist that can be used to determine priority • Iterate remediation efforts to progressively dilute them • We can measure success
