Isn't it risky to kill a design based on 5 data points only? You're leaving a lot up to chance... you could simply have been unlucky and fallen on 5 people who don't like it whereas the next 15 would have loved it. I love the design sprint concept but I'm concerned about the statistical significance of the data on day 5...

To put it more simply.. if you flip a coin 5 times and get tails 5 times, does it really mean you have 100% chance of always falling on tails?

This is a widely accepted model for finding usability mistakes

In 5 real life tests you'll have more than enough qualitative information to decide where a design is failing

This is a great ITW. I love reading Sean Ellis via his guest posts and growthhackers.com. Great to hear him talk. Thanks Eric. Keep these up!

Une vraie caverne d'alibaba!! Si vous cherchez des accessoires proches des modèles dans les magazines et à des prix complètement raisonnables n'héistez pas. Pour moi c'est le meilleur choix et rapport qualité prix du quartier (J'y vis depuis 10ans). A vrai dire je n'ai pas encore trouvé mieux à Paris. Ils ont tout à des prix plus que sympathiques. J'ai acheté des sacs en cuir à 60€ (de toutes le couleurs) des bracelets que j'ai déjà vu à Passy à 70€ étaient ici à 20€ (exactement les même, je m'étais fais avoir) et rien ne s'est cassé pour l'instant. Seul hic, la clim était cassée la dernière fois que je suis passé. J'espère qu'ils l'ont réparé :) Aussi.. accueil très sympa, bonne ambiance et juste à côté de Kiliwatch :) Parfait quoi...
