Contribution
Self initiated Project
This project was done for WBA - Wholesale Business Analytics which offers different telecom operators to record and manage the journey of a deal that includes, budget forecasting and settlement.
When I saw the screens, I realised the need to make their products accessible for everyone because of its complexity and use of colour contrasts.
I pitched them to take this up as an Initiative to improve their overall experience.
We identified
More than 35% of
users have visual disabilities
About WBA
WBA (Wholesale Business Advisor) is one of the products which Mobileum offers to multiple operators in the world to records and manage a journey of a deal.
Constraints
Since it is an ongoing live product, we could not make a lot of structural changes. We could only go to that route with time.
No scope to accommodate as a separate task, should be a picked up with other ongoing big enhancements
PRODUCT GOAL
Redesign the existing interface to make it accessible for everyone to use
My Role
Strategize and execute plan while accommodating the usual goals and responsibilities of the bigger picture
My Approach
Discovery
I began by meticulously delineating the WCAG Guidelines' parameters, ultimately crafting a comprehensive checklist by amalgamating various sources and supplementary guidelines for AA standard.
Implementation
After carefully reviewing the checklist, I went ahead with the analysis of the current design to determine the minimal changes needed to accomplish our objective.
Design
At this stage, I incorporated all the changes in the existing screens without much structural change ensuring the accessibility score increase to match AA standards
I began by understanding
How is this interface perceived
*Evaluated this screen for various color blindness disabilities and other vision disabilities.

Checklist Mapping
After reviewing various web checklists and standards, I found it challenging to maintain organization and ensure future scalability.
As a solution, I created a checklist adhering to the AA standard, which can be utilized to assess any screen with ease.
