Transforming Pharmacy
Supply Chain at Scale
Role: Lead Product Designer | Company: Walgreens Pharmacy

Quick Facts
Role: Lead Product/Service Design
Company: Walgreens Pharmacy
Scope: Supply chain workflow redesign + enterprise design system migration
Impact: ↓22% drop in call center inquiries; 30% reduction in fulfilment time
The Challenge
However, the objective wasn't just a visual "reskin." We had to keep the pharmacy operations running ("keep the lights on") while simultaneously scrapping and replacing inefficient, legacy workflows. If a process was identified as a hurdle to accuracy or speed, we rebuilt it from scratch—even if it meant the pharmacists had to retrain.
Why This Mattered
-
Inefficient workflows were slowing down inventory tracking and approvals, leading to revenue loss and pharmacist fatigue
-
As a mandatory pivot point, any "nice-to-have" stayed as-is to ensure continuity
-
Critical inefficiencies were redesigned entirely to ensure the new platform was a high-performance asset
My Role
I led a research-driven redesign initiative—identifying root causes of inefficiency, deciding what to keep and what to kill. I spent time in pharmacies to understand exactly which parts of the old system were non-negotiable so that we wouldn't break critical habits during the migration.
Key Insight
When presented to the executives to get their buy-in for a system-wide transformation, we concluded that the problem wasn’t just the interface.
The workflows themselves were broken—impacting how the supply chain operated day-to-day. Fixing the UI without rethinking the system would only recreate the same problems in a new design language.
Approach
1. Deconstruct the Inefficiencies: I used contextual inquiry to watch pharmacists interact with the inventory. If a workflow forced them into manual workarounds or "memory-heavy" tasks, I flagged it for a total rebuild rather than a migration.
2. Developed New Interaction Standards: For the scrapped workflows, I designed new interaction patterns within the Microsoft Fluent framework. These weren't just new looks; they were new ways of working—engineered for speed and error prevention.
3. Validate the "New Normal": Because we were introducing new ways of working, I used usability testing to ensure the new workflows were intuitive enough that the "learning curve" for retraining was as short as possible.


The Transformation
-
From: A cluttered system of "legacy habits" and inefficient inventory tracking
-
To: A high-speed, omnichannel ecosystem built on modernized logic and proprietary control

The Result
I restructured the platform’s information architecture and proposed a new dashboard model based on familiar patterns—using table-based layouts to support large-scale data visibility and drill-down workflows. This aligned quickly with stakeholders and secured initial approval.
-
Speed to Value: The new workflows cut fulfilment time by 30% almost immediately
-
System Stability: We successfully navigated a "non-negotiable" overhaul of critical tasks without disrupting nationwide pharmacy service
-
Reduced Overhead: Cleaning up the logic at the root caused a 22% drop in calls to the help desk

Refine — Challenge assumptions
Rather than stopping at approval, I questioned whether the solution truly improved the experience.
I explored an alternative: a list-based view—allowing users to scan global data and access details inline.
It reduced clicks and improved real time decision-making.
Scale — Extend across contexts
The new pattern:
-
Reduced interaction steps
-
Improved data visibility and speed of use
-
Scaled naturally to mobile, through nested adaptive views

Final Outcome

The result was a more efficient, flexible system that not only solved the original workflow challenges—but improved how users interact with data across devices.
