Vision Center Last-Mile Delivery

Overview

Walmart wanted to enable same-day contact lens delivery directly from Vision Center inventory, allowing eligible online orders to be fulfilled locally and delivered within hours. While the customer experience was already being developed, the operational model required to support fulfillment had yet to be defined.

Once a customer places an order, how does that order reliably make it from a Vision Center shelf to a customer's doorstep?

Unlike traditional retail fulfillment, Vision Centers were never designed to function as delivery hubs. Inventory was limited, fulfillment processes did not exist, and operational requirements were still evolving. I joined the project to define the associate experience and establish the workflows required to make the service operationally viable.

While the customer experience focused on purchasing contact lenses online, the associate experience needed to account for everything that happened afterward: inventory validation, preparation, packaging, driver handoff, delivery recovery, inspections, order changes, and customer support scenarios.

Delivery would only be as reliable as the operational system behind it, and that system didn't exist yet.

The situation

Several weeks before I joined the project, leadership had requested estimates for the associate-side experience needed to support delivery. As customer-facing work expanded and requirements evolved, executive attention increasingly shifted toward the unfinished operational side of the initiative.

By the time I became involved, timelines were compressed, expectations were high, and many operational questions remained unanswered. The initial requirements described the concept but left significant gaps in execution details.

At the same time, stakeholders across Vision, delivery, operations, engineering, compliance, and product all had legitimate concerns that needed to be addressed. What initially appeared to be a straightforward delivery initiative quickly revealed itself as a much larger operational challenge.

The real question: how do we make sure every order can be prepared, handed off, tracked, recovered, inspected, modified, and completed when real-world conditions go wrong?

The outcome

In less than five weeks, I delivered a complete workflow architecture for Vision Center last-mile delivery, spanning order preparation, packaging, driver handoff, failed delivery recovery, inspections, order changes, and inventory reconciliation.

Three engineering-ready specification packages turned a high-level delivery concept into an operational system stores could execute, and gave stakeholders confidence the service would work reliably, not just in theory.
