Product and design teams make a lot of decisions. Early on in the development of a product, they will be thinking about features — such as what the product should do, and how each feature should work. Later on, those decisions become more nuanced — such as ‘what should this button say? Each decision introduces an element of risk — if a bad decision is made, it will reduce the chance for the product to be successful.
The people making these decisions rely on a variety of information sources to improve the quality of their decision This includes intuition, an understanding of the market, as well as an understanding of user behavior. Of these, the most valuable source of information to put evidence behind decisions is understanding our users.
