The text discusses the importance of conducting a feature audit to understand how users are actually using your product's features. It highlights that most users do not use all the features in a product and that some features may be poorly adopted or irrelevant to certain user groups. The author suggests four options for dealing with underutilized features: killing them, increasing adoption rates, increasing frequency of use, or improving their quality. To increase adoption rates, it is essential to identify the root causes of why users are not using a feature and resolve these issues. Increasing frequency of use involves identifying changes that will get existing users to use a feature more often, often by creating habits with four key elements: trigger, action, reward, and investment. The text concludes that conducting a feature audit is a powerful tool for product teams to focus their work on areas where it has impact and avoid valueless pixel pushing.
