The Challenge
For decades, Walmart Vision Centers have utilized outdated legacy platforms and burdensome paper-based processes which impact the associate and patient experience. To improve patient order times, enhance the associate experience, and realize millions in cost savings, Walmart needed to innovate and embrace new technologies in the Vision Centers.
The Outcome
Through a months-long process of user research, discovery, compliance reviews, stakeholder reviews, and hundreds of design iterations, our team launched the MVP release of a new native iOS iPad app for associates and patients.
This app enables associates to do their work as they move about the Vision Center (no longer tied to a desktop and a filing cabinet) and digitizes critical steps in their workflow, such as managing patient records, handling HIPAA-related legal documents, and enrolling patients in automated text messages about their orders.
Furthermore, this MVP release laid the foundation for many future releases, such as digitizing prescriptions, allocating patient insurance, managing orders, and more.
Business Needs
1.
Reduce the average patient order time to increase throughput and sales.
2.
Cut transactional costs by automating and digitizing current manual processes.
3.
Improve the associate experience by providing modern tools that enable them to work more effectively.
4.
Minimize HIPAA breaches through secure digital record keeping and removing paper-based record retention.
User Research
This technology modernization project would significantly change how Vision Center associates supported patients and went about their daily tasks. With this in mind, we began our project with a series of user research interviews with Vision Center associates to develop empathy for what they loved and hated about their work.

Associate Quotes
💬 “So much of our time is spent on navigating the software. We should be focusing more on patient needs.”
💬 “Our systems make us look incompetent at times instead of like knowledgeable professionals.”
💬 “It's taking forever, and people are just looking at you...we get nervous because people are waiting, and work keeps piling up.”
💬 “Our cabinets are so jammed full of files that they're breaking.”
MVP User Flow
While our North Star vision for the iPad app entails full feature parity with the current legacy platform and enhanced ways of working such as utilizing OCR for automated prescription scanning and intake, our MVP would need to be one small step towards that North Star experience.
We collaborated closely with our product, business, and engineering partners to ensure that our MVP experience could stand independently and deliver value immediately to our associates, patients, and the company.

Iterative Design Process
Through a highly collaborative design process, our team, which consisted of myself and the lead designer, worked through hundreds of iterations based on constant reviews with key stakeholders.
User Testing
Amid our ongoing design reviews and iterations, we conducted a usability research study with 5 Vision Center associates in the field to test our iPad prototype and gain valuable insights from our end users.
Research Findings
Through our usability study, we discovered that many aspects of the designs were easy and intuitive and didn't require any training to understand. However, we also uncovered specific steps or components that caused concern or hesitation for associates that were critical opportunities for us to improve.
We took our findings back to our stakeholders and informed them of how we would plan to evolve our designs to address these learnings.
Iterations
With research insights from user testing, we made design updates throughout our prototype to address critical issues. Below are a few examples of our iterative approach.
Continued User Testing & Findings
We conducted an additional round of usability testing with field associates. We found that we had addressed many of the pain points discovered in our first round of testing. Additionally, we uncovered a few small opportunities for improvement and other larger items to keep in mind for future releases.
Final Iterations
We made updates to our designs based on our second round of usability findings and went through several more design reviews and updates to polish the look and feel of the iPad application.
Engineering Handoff
Once we received final leadership approvals, I prepared our source of truth file for our engineering partners. Over the course of this project, we hired many new iOS engineers who weren't familiar with Walmart's design system and components, so we took extra care to annotate in great detail to ensure interactions and design specifications were clearly documented.
Outcomes
The MVP version of this iPad app was rolled out to all 3,000 Walmart Vision Centers by the Spring of 2023, streamlining daily processes for 15,000 associates and reaching 6.5 million patients annually. Since launching, the Vision Center Associate Experience team has continued to build upon this foundation and the app now supports adding prescriptions, looking up insurance benefits, and ordering prescription eyewear.
Below are some of the key success metrics from this initial launch:
1.
Three minutes per patient order saved by beginning the patient lookup or profile creation process on the iPad while the customer is browsing for frames.
2.
Three minutes per patient order saved on back office time spent by the associate by digitizing the signing and collection of HIPAA legal documents.
Additionally, this saves Walmart associates from printing, filing and storing 6.5 million pieces of paper per year.
3.
Since the launch of the new iPad app in all Vision Centers in Q2 of 2023, the Vision Center NPS rose from 72 to 84 showing the impact on the customer experience.
