Let’s look at a couple of examples. When Intuit’s tax group began to think about mobile apps, Carol Howe, a project manager and innovation catalyst, started with the customer. Her five-person team went ”out in the wild, ”she says, to observe dozens of smartphone users. It quickly narrowed in on millennials, whose income range made them likely candidates for the simplest tax experience. The team created multiple concepts and iterated with customers on a weekly basis. They brought customers in each Friday, distilled what they’d learned on Monday, brainstormed concepts on Tuesday, designed them on Wednesday, and coded them on Thursday, before bringing the customers in again. Through these iterations the team uncovered multiple “delighters.” They launched a pilot in California in January 2010 and expanded nationwide in January 2011.
