Spot Your Specialist: Data Scientist, Data Manager or Data Analyst?

Lately, it's all about data, and it makes sense. With around 2.5 quintillion bytes of data created every day and an estimated 163 zettabytes of digital data to be generated by 2025, it's no wonder companies are rushing to make the most out of the information their users generate daily. But, leveraging this massive amount of data calls for very specialized help. To do so, companies may look to IT outsourcing companies or other providers to help them fill the gap, but a lack of clarity on the type of professional or area of specialization needed may hinder their efforts.

For companies looking to make the most out of their data, data scientists, data analysts, and data managers are usually the best fit to help identify, collect and evaluate data. However, each role has varying characteristics and depending on the goals of the organization, it's important to select a person with the right skills to face these data challenges. Consequently, it's not uncommon for companies and recruiters to feel confused when it comes to hiring a data-oriented specialist. It's even more important to hire the right person for the job not only to save time and money but also to ensure that a person is able to grow and feel challenged in the right role.

So, data scientist, data analyst, or data manager: what's the difference?

Science, Management, or Analytics

When we talk about data, we're talking about information. So, the difference between these disciplines is how deep a specialist goes into the analysis of that information. That's the short version, anyway. The longer version requires we consider a couple more factors than just depth of study.

For instance, data science looks at the bigger picture, covering various disciplines and understanding where information comes from and how to capture the right info. A data scientist can predict trends, explore data sets—structured or unstructured—and use statistics and mathematical models to inform decisions.

Data analytics, on the other hand, also deals with data analysis, but is generally more interested in gaining insights to specific questions or objectives. A data analyst works with databases and manipulates data to either support or challenge a given strategic decision but won't necessarily consider information that does not pertain to it.

Lastly, data management focuses on making sure data usage and operation is efficient and effective. A data manager oversees the integration of data management processes with other processes to meet service level requirements, and they act as an interface to other groups, like business systems and data center.

Think of it this way: a data analyst is scavenging a trail, finding tracks, and following a map to find a pot of gold. A data scientist is looking at the land, reading the natural signs and making associations between different elements to find ways of hitting a gold-bearing vein. A data manager is making sure the gold extraction operation is running smoothly.
