Scenarios
Listing features is a start, but thinking through a beginning, middle, and end shows how someone experiences them.
Overview
This is one of the most powerful ideation tools you can have. You don't need to be an expert at process mapping or drawing perfect screens. The basics are easy — just literal boxes, arrows, and some text.
People often think of new products or features but don't put time into thinking about how something flows. This is one of the most important parts of ideation, and one of the easiest.
What steps does someone take to use a feature? How do they start, maintain, and finish? Doing this exercise helps you think further ahead and more fully prepare an experience that's useful and delightful.
You do this every day in your own mind when you think about where to park at the grocery store, what's on your list, what aisles you'll go down, and whether you'll use self-checkout.
Consider the Peak-End Rule
The peak-end rule is a concept in psychology that suggests people judge their experiences based on the emotional intensity of the peak (the most intense moment) and the end of the experience.
This means the way an experience ends has a big impact on how people remember and evaluate it. So when designing an experience, consider not just the overall flow, but the emotional impact of specific moments and the way the experience ends.
