Retail is more advanced than ever, yet 90% of shoppers describe in-store shopping negatively, costing retailers $262 billion in lost sales anually.

The modern retailer-shopper dynamic exacerbates two acute, reinforcing pain points: retailers are underinformed and shoppers are overwhelmed.

"…65 % of the time we do not know who's shopping"

"Shopping in-store is.. overstimulation..."

Problem

Apparel retailers are losing $262B in in-store sales because of the shopping experience they're providing.*

Through interviews with 40+ retailers and shoppers we learned that shoppers are desperately overwhelmed with in-store shopping and retailers are drowning in the noise of products.

*Forsta's 2024 retail customer experience study
**McKinsey & Co Next in Personalization 2021 Report 

"Shopping in-store is overstimulation... I get really antsy if I can't find something, and I'm looking and looking and looking, I'm like, there's no point of me being here.."

"Shopping in-store is.. overstimulation... I get really antsy as well if I can't find something, and I'm looking and looking and looking... I'm just like, there's no point of me being here let's move on.."

Foundational Insight

In-store personalization is the answer - but there's an absence of data to make it happen.

Through follow-up interviews with retail SME’s, we learned that retailers are data starved when it comes to in-store shopping. As such, they’re trying to gather data from customers through every means possible.

“Without a rewards account to associate with a purchase, we miss a very large area of data...65% of the time we do not know who's shopping.”

Retailer's data collection is leaving shoppers exacerbated and their needs unattended. Shoppers want tools to support their shopping journey, but instead are receiving overwhelming data requests that don’t seem to provide value.

The Big A'HA

The retailer approach to personalization, one which extracts the most possible data from shoppers, is a failing recipe.

Design Implication

Our in-store personalization solution can serve as a data bridge between shopper and retailer.

Analysis + Journey

A successful solution would create enough value for shoppers to earn their trust and ultimately, data.

Designing for the Prep phase allowed us to leverage existing behavior (80% of shoppers already prep for their shopping before going in-store!) to positively affect the journey downstream.

Prototyping: Experimentation

Through 30 rapid prototyping experiments, we tested shopper needs and openness to our AI-enabled ideas.

The top shopper needs we uncovered were Autonomy, Confidence, and Respect around data sharing. We broke down each need further to test boundaries and ultimately form our design principles.

To understand desirable features, we presented shoppers with various concepts that accomplished different jobs in the preparation phase.

We then measured the feasibility of each feature weighed against its desirability.

Prototyping: High Fidelity

With our concept and features finalized, we ran 3 rounds of usability testing to refine our UI flows, design system, and value offering.

We conducted intercepts, A/B tests, and moderated usability tests with 20 shoppers. Specifically, we tested for task completion, interest, and error rates.


These were some of the design decisions coming out of our testing.

Q1

How and when should our AI filters be applied to a search?

Insight

Shoppers would rather spend time correcting filters than refining their algorithm up-front.

Design Decision

Collect enough data to auto-apply mostly correct filters, and allow shoppers to edit whenever.

Q2

Do users understand and value the visual approach to algorithm refinement?

Insight

Visual product refinement is a new retail paradigm - one that may initially confuse users but resonates once understood.

Design Decisions

Clarify instructional language and design interactions that mirror the flexibility AI tools they're used to using gives them.

Q3

How can our product cards support informed, yet quick decisions?

Insight

Shoppers want ALL product information, but some are more critical than others.

Design Decision

Balance information access and cognitive ease through progressive disclosure that prioritizes the 5 most time-relevant pieces of information:

Final Product + Success Metrics

80% of our final testers expressed a willingness to pay 99 cents to download our app.

Proving Our Value

Cerulean was co-designed for shoppers AND retailers.

Though we prioritized shopper needs in our design to begin, our strategy always considered retailer needs. We consulted with 8 major retailers constantly, ensuring that we were keeping their constraints in mind.


While we ran out of time to pressure test retailer willingness to buy our solution, we did gauge retailer interest. Three retailers, including Walmart and American Eagle Outfitters expressed interest and support for our solution.
