According to expert360, data science is one of the fastest-growing industries in 2021.

It’s an extremely important and high-demand role that can have a significant impact on a business’s ability to achieve its goals, whether they are financial, operational, strategic, and so on.

Company’s collect a ton of data, and much of the time it’s neglected or underutilized.

This data, through meaningful information extraction and discovery of actionable insights, can be used to make critical business decisions and drive significant business change. 

It can also be used to optimize customer success and subsequent acquisition, retention, and growth.

As mentioned, data scientists can have a major positive impact on a business’s success…

And sometimes inadvertently cause financial loss, which is one of the many reasons why hiring a top-notch data scientist is critical.
