Name a product that has poor accessibility. How would you improve it and measure the success?

A product with poor accessibility is a common mobile banking app that lacks screen reader compatibility and sufficient color contrast. To improve this, I would first conduct user testing with individuals who rely on assistive technologies to identify specific pain points. Then, I would implement ARIA (Accessible Rich Internet Applications) labels for all interactive elements, ensure a minimum color contrast ratio of 4.5:1 for text and background, and provide adjustable font sizes. Success would be measured by increased task completion rates for users with disabilities, positive feedback from accessibility audits, and a reduction in reported usability issues related to accessibility.
