Walmart Contactless Auto Experience

Led end-to-end program management for a high-priority customer auto care enhancement featuring self check-in and IoT-based lockbox integration.

Tire Installation Self Check-In

About the Project

As part of a broader initiative to launch Auto Care Center of the Future experience, I led a program to enhance an existing tire installation flow. Previously, customers could buy tires online and schedule an installation appointment. The goal of this enhancement was to introduce a Self Check-In feature that allowed customers to check in on the day of their appointment, support scenarios with less than four tires, and integrate IoT-based lockboxes for key drop-off.

The program was high-priority, tied to executive goals, and came with a tight launch deadline to launch by the end of September. The feature would pilot at a store already remodeled with vendor-installed lockbox systems and then roll out to additional stores in phases.

Goals:

  • Simplify the in-store check-in process for tire installation appointments
  • Enable self-service check-in on appointment day
  • Support flexible tire purchase scenarios (less than four tires)
  • Integrate IoT lockbox systems for secure key drop-off
  • Launch pilot by end of September to meet executive commitments

My Role

  • Owned end-to-end program management, including planning, technical discovery, execution, launch, and vendor coordination
  • Aligned and coordinated across 12+ cross-functional teams including Cart, Checkout, Fitment, Auto Care, IoT Integration, Order Amendments, Check-In, Comms systems, and In-store systems
  • Acted as the central point of accountability for delivery timelines, API coordination, technical dependencies, and cross-team execution
  • Managed third-party vendor relationships for IoT lockbox integration

Program Management Approach

  • Program Planning & Architecture Definition
    • Partnered with Product, Design, and Architecture to define user entry points, check-in flows, and system requirements for customer check-in, parking instructions, and key drop-off at lockbox
    • Collaborated with architecture teams to map new data flows and interactions between multiple legacy and modern systems, especially around fitment, cart, and order management
    • Defined feature boundaries and scope to prevent scope creep while accommodating edge cases
  • Cross-Team Alignment
    • Mapped dependencies across 12+ teams including Cart, Checkout, Fitment, Auto Care, IoT Integration, Order Amendments, Check-In, Comms systems, and In-store systems
    • Conducted product walkthroughs, UX design reviews, and high-level technical design (HLD) walkthroughs to secure early alignment and understand level of effort
    • Facilitated decision-making on technical approaches, user flows, and integration patterns
  • Tech Discovery & API Coordination
    • Led technical discovery sessions to define and finalize APIs across systems
    • Established clear responsibilities, sequenced data flows, and addressed edge cases like fewer than four tires and rescheduled appointments
    • Collaborated with engineering managers to set realistic development timelines once APIs were finalized
  • Testing Strategy
    • Worked with Product to define comprehensive end-to-end test scenarios covering both front-end and back-end flows
    • Created testing strategy involving upstream and downstream integration testing using test items
    • Coordinated End-to-End War Room testing, simulating the full customer journey from tire purchase to key drop-off at the store
    • Ensured IoT testing aligned with vendor availability and store readiness
  • Release Coordination
    • Drafted production release playbook covering configurations, rollout scripts, rollback plans, and communications
    • Coordinated vendor management to ensure lockboxes installed in stores could receive signals from our application via IoT platform integrated with store network
    • Secured sign-offs from Product, Engineering, and Business stakeholders before executing release plan

Tech Details

Systems Integration
Complex integration across legacy and modern systems including Cart, Checkout, Fitment, Order Management, and Auto Care platforms. Designed to handle real-time data synchronization and state management across the customer journey.
IoT Platform
Integration with third-party vendor's IoT lockbox system via platform APIs. Enabled secure communication between the application and in-store lockbox hardware for key drop-off functionality and status updates.
API Architecture
Defined and coordinated multiple APIs across systems to support check-in flows, order amendments, fitment validation, and lockbox operations. Established clear contracts, error handling, and retry mechanisms for robust integration.
Testing Framework
Multi-layered testing approach including unit testing, integration testing with test items, and comprehensive end-to-end War Room testing. Simulated real customer scenarios from online purchase through in-store check-in and key drop-off.
Release Management
Comprehensive release playbook with phased rollout strategy, configuration management, rollback procedures, and coordinated communications across teams. Designed for minimal disruption and quick issue resolution.
Store Systems
Integration with in-store systems for appointment management, customer notifications, and service workflow coordination. Ensured seamless handoff between digital check-in and physical service execution.
