I'm not going to pretend to be an expert at it, but BI tools let you interrogate your data. This can be used for endless use cases for basically any department in an organization. But for instance, if you're a sales leader you might have some questions about all of the sales and marketing data in your company to focus your team's efforts for the next quarter. When you figure out which questions are actually returning useful findings, you then can take a set of these and build a dashboard which lets you easily re-examine those particular questions and their results with always up-to-date (or up-to-date-ish) data and can easily share it with the team.
