First trip since Feb. 2020
Hi! I’m Eva :)
Dead horse? @evaferreira92
Beating a Dead horse @evaferreira92
To waste time and effort trying to do something that
is impossible. “ ” Mr. Merriam-Webster
Tech Debt.

What is Technical Debt? And… what isn’t Technical Debt?
¿Bad Code?
Bad Code = Lack Lack of knowledge, lack of caring,
lack of quality control
Bad code is usually more harmful than Techical Debt @evaferreira92
¿Tech Debt?
Technical Debt is a conscious Trade-off
It happens when we choose to gain something otherwise-unattainable immediately
in return for paying it back (with interest) later on. “ ” Mr. Harry Roberts

The Theming Example
!important all the things
This is my garbage and I’m proud of it. @evaferreira92
@evaferreira92
@evaferreira92
Congrats! You have just created Technical Debt! Now… will you
repay? @evaferreira92
None
None
Consequences of not repaying • Accumulates interests • Snowball effect
• Team members are sad @evaferreira92
Repaying Tech Debt The Accessibility Part
An annual accessibility analysis of the top 1,000,000 home pages
How many passed a basic WCAG test?
WCAG includes (but not limited to) • Alternative texts for
images • AA Contrast ratios • Labels for inputs • Document language attribute • Buttons and links with discernable texts @evaferreira92
At least 20%? @evaferreira92 At least 10%? At least05%?
At least 20%? @evaferreira92 At least 10%? At least05%?
At least 20%? @evaferreira92 At least 10%? At least05%?
At least 20%? @evaferreira92 At least 10%? At least05%?
Only 2,6% passed. @evaferreira92
Most common errors • Lack of alternative texts for images
• Non-compliance color contrasts • Lack of labels for inputs • Lack of document language attribute • Buttons and links without discernable texts @evaferreira92
<html lang="es">
Fun facts “Despite being 2021, 14,501 home pages had <marquee>
and 341 home pages had blinking content (<blink> or text-decoration: blink).” https://webaim.org/projects/million/
Why does this happen? Lack of accessibility is more often
than not, a conscious trade-off.
None
How do we begin repaying? Repaying accessibility technical debt
Current Tech Debt Improvements to current a11y bugs
Spare time to improve it • Small, well-defined tasks
15% of sprint • Fix bugs • Rebuild broken components • Build new features Skip navigation, etc. @evaferreira92
Track and document @evaferreira92
None
You can’t repay what you don’t acknowledge @evaferreira92
Avoid creating more (Accessibility Technical Debt)
Long term warning! The following recommendations might take soooome time
Cultural change in the company You need people who care.
@evaferreira92
Update processes • Automated tests Built into CI •
Manual tests • QA Process • Internal demos with Screen Reader @evaferreira92
Design Systems • Fix a11y here! Colors, contrast, font-sizes,
font families Labels and alts • Whatever what Brad Frost and Jina Anne say @evaferreira92
None

Hire Front-end developers @evaferreira92
Hire Front-end developers @evaferreira92
No code can fix bad design. If the design is
inaccessible, so is the website.
Bad UX flows

@evaferreira92
Team work It’s not 1999 with webmasters doing the whole
thing anymore
None
You can’t avoid Tech Debt But you CAN avoid putting
the burden on users with disabilities
Thank you! @evaferreira92
