Ask HN: Why do companies struggle to find relevant insights in business data?

I'm currently investigating the data analytics market to see if it is a good spot to start a business and love to get your insights.

There are myriads of business intelligence, data analytics and management reporting tools on the market. However, it seems that businesses have a hard time to find relevant (business) insights in their data. Why do you think this is? What are these tools, and the business that use them, struggling with? Please don't think just about these tools and their features, but also about the people using the tools, the processes behind, etc.

Would be great if you could state your role or position, to help me understand what your background is.

Thanks!
