When Albert Einstein was a professor at Princeton University in the 1940s, there came the time for the final exam of his physics class. His assistants passed the exam forms to the hundreds of students, and the hall was dead silent. One of the assistants suddenly noticed something was wrong.
She approached Einstein and told him that a mistake had been made with the exam form and that the questions were the same as those in the previous year’s exam. Einstein glanced over the exam form and said that it was OK. He explained that physics had changed so much in the last year that the answers to the questions were now different.
Metrics can be a touchy subject in design. When I say things like, “Designers should embrace A/B testing” or “Metrics can improve design,” I often hear concerns. Many designers tell me they feel that metrics displace creativity or create a paint-by-numbers scenario. They don’t want their training and intuition to be overruled by what a chart says a link color should be.
These are valid concerns, if your company thinks it can replace design with metrics. But if you use them correctly, metrics can vastly improve design and make you an even better designer. First, when I talk about metrics, I’m talking about making use of a couple of very specific tools, i.e. user analytics as well as A/B or multivariate testing.
The entire process of designing digital applications comes with many challenges and decisions. For the majority of projects, you will be designing in somewhat familiar territory. But what happens when you have to design something to be used by hundreds of children around the world? How do you accommodate your design for kids of different ages and backgrounds? What special challenges emerge, and how can they be overcome?
For a project of this scale, the design process we follow might require modifications. These modifications would be to accommodate the needs of younger age groups and would shape the entire length of the project, from user research, brainstorming, interface design and interaction design all the way to the final stages of usability testing and user support.
