BI consultants seek to understand a business and its goals, interpret data, and offer advice to ensure goals are met. Consultants also work to improve the BI process by designing or redesigning data analysis protocol and carefully selecting [business intelligence software](https://www.g2.com/categories/business-intelligence). BI consultants frequently have industry-specific knowledge alongside their technical backgrounds, with experience in healthcare, business, and other fields. BI consulting firms often provide other consulting solutions, such as [implementation services](https://www.g2.com/categories/implementation-services) and [IT strategy consulting](https://www.g2.com/categories/it-strategy-consulting).
