What We Were Solving

Best Buy's product assortment needed to grow to better serve our customers. Leadership decided that a third-party (3P) marketplace was the best way to expand quickly. We were tasked with creating a buying experience for 3P that maintained the experience customers expect from Best Buy.

The challenge was significant: how do you introduce third-party products into a trusted retail environment without compromising the customer experience that Best Buy is known for?

What Made This Hard

Customers had to feel confident that 3P products were legitimate and backed by Best Buy. At the same time, the business decided that paid member benefits like free shipping and protection plans would not apply to 3P products. That created a unique messaging challenge.

Core tension: Teams were having trouble communicating transparently without confusing the customer.

We needed to balance business constraints with customer expectations, ensuring trust while being transparent about different terms and benefits for marketplace products.

What I Did

I led the team, execution, and cross-functional relationships across product, engineering, and supply chain. I initiated user research and presented our direction to leadership throughout.

I had the team define marketplace principles based on third-party shopping research. We combined that with lessons from our recent checkout redesign to guide a design that built trust.

We used iterative design and evaluative research to reduce usability and value risk. I created space for early exploration and encouraged bolder ideas. We reviewed our work with real customers to improve confidence and comprehension at each step.

Key leadership actions:

  • Managed 5 designers including 4 direct reports covering content and product design
  • Facilitated cross-functional alignment across multiple stakeholder groups
  • Established research frameworks for marketplace trust and usability
  • Presented strategic direction to executive leadership

How We Worked

We moved through discovery, exploration, evaluation, iteration, and then scenario design. We used a mix of customer sentiment research and market studies to guide our content and UI decisions.

Our biggest constraint was the lack of member benefits on 3P products. Instead of focusing on exclusions, we led with what was included and used familiar UI patterns to keep things simple and trustworthy.

Design principle: Lead with what's included, not what's excluded. Use familiar patterns to build trust.

What Happened

The feature just launched, but every round of testing showed improvement. Customers felt more confident in 3P purchases and understood key details like return policies and pricing differences.

The work was praised across internal teams and recognized by leadership. It was highlighted at town halls and mentioned in public earnings calls as a key strategic effort.

Strategic impact: It created a foundation for Best Buy's future business model, supporting marketplace growth and retail media investment.

What I Learned

I don't need to be involved in everything to have an impact. I can support other leaders by giving them tools and frameworks that help them lead more effectively.

I saw my team embrace bold exploration and become more confident in their decisions. If I could go back, I'd push for higher quality earlier in the process.

"When we have aligned goals and trust in each other, the work becomes more fun and more successful."
— Key insight from the project

This project reinforced the value of iterative research and the importance of balancing business constraints with customer needs. The success came from building trust through transparency and familiar patterns rather than trying to hide limitations.
