Inspired by a recent prompt from my beloved design group, El Corazon de la Design, to redesign a shopping experience, I’m going to explore the paradox of choice.
One of the classic interaction design problems is allowing people to narrow down a huge number of possibilities to a couple that are of most interest to them.
Matching a user with something that makes them happy is the goal. This is the purpose of every collaborative filtering engine, music recommendation service, and online store.
The need for help in decision making occurs in situations where:
1. People cannot test before they choose.
2. Products look similar.
3. There are a huge number of products available.
4. People often come in uneducated about what they want.
5. The difference between a “Good” product and a “Bad” product requires education to realize.
I decided to study a prime example of disambiguation of products to find how a store can help customers choose what will make them happy. I spent an afternoon at K&L Wine Merchants in SOMA of San Francisco. Wine is a great example of an ambiguous product. All bottles LOOK the same, but there is a rich culture surrounding wine that purports huge differences in flavor and quality between bottles.

With the wine store as inspiration, I will go through the forms of decision help that I observed:
Matchmaking
Read Stuart Skorman’s book, Confessions of a Serial Entrepreneur, and he talks about how to build a video store to help customers find the perfect movie. He calls this “movie matchmaking.”
The way this works at K&L is that employees ask customers “What are you going to be eating with the wine?” or “What other wines do you like?” These are two classic tools of recommendation: through pairing, and through similar tastes. With a bit of education an employee can make good recommendations.

Exaggerated Opinions
At K&L, employees spend time tasting all of the wines they sell (this is A LOT). In my time at K&L, I overheard one customer yell “What do you think of this Pinot from Oregon?” an employee replied “That one… It’s OK. It’s not European, but is full of ripe fruit.”
Employees need to be able to show they are competent, but with something like wine, where taste is so subjective, it doesn’t really matter what they say. Most customers will see them as experts as long as they appear confident in their opinions.

Editorial Recommendation
The wine world is rich with reviews, and also plagued by them. The most famous are the Wine Spectator point rankings. Wineries live and die by a simple 0-100 point score.
Universally known point scores give customers a simple way of scanning many products and pulling the few best that match their price point.
At K&L, they label some of their wines with editorial reviews and often mention the wine scores. They do not show the scores often and obviously. It is clear that they want to sell wines by more than just numbers. Offering such a simple decision making tool, doesn’t allow K&L to form a closer relationship with their customers through personalized recommendation and community education.

Community Building
To develop loyal and educated customers, K&L offers two forms of community education, a newsletter and wine tastings.
The newsletter is nothing special, but it gives customers something to take with them and read on the couch, dinner table or toilet. It educates about new wine trends, and informs about deals.
Tastings teach people to speak the language of wine, form relationship with employees, and have fun. It is a way to let people join the exclusive cult of educated wine consumers. Tastings of course, also sell a lot of wine.

Wrapping up
With a product like wine, where quality is very subjective and taste varies from person to person, what it all comes down to is building a story around a wine. Any of the techniques I spoke about will do this. All a customer needs is a one-liner to tell at the party they are hosting. This could be “This is a 92-pointer” or “This wine goes perfectly with lamb” or “I tasted this at K&L and loved it.”
When selling products we all need to realize, education can only go so far. People don’t need to know everything about the history or specs of products, but they DO need to feel good about WHY they made the decision they did. All we are doing in helping a customer make a decision is to arm them with something to think about while they sip or something to tell their friends as they uncork.
