Business intelligence (BI) tools aim to provide easy ways to visualize data, in order to better identify actionable insights.
This is especially important when the modern business can now collect data on every aspect of a business, from sales and marketing, to workflows and productivity, to hiring and HR, to overall performance and profitability.
However, many of these data points exist in isolation and require the best BI tools to connect the dots together. This is what business intelligence represents: the ability to not just look at a specific detail of business operations, but tie in key information from each angle into an overall whole.
This can then allow for real insights and predictions for improving business performance, not least through Key Performance Indicators (KPIs). A number of software packages also come with their own analytics, but these can also usually be exported into a business intelligence platform.
