Selecting Right Data Scientists Leads To Growth & Stagnation In Data Driven Business

Data science is a process of analyzing data using creative ways and using algorithms to develop technologies and finding solutions to the complex issues. These involve pulling apart and putting together data sets to reveal hidden patterns such as consumer habits and preferences. It may also be simply figuring out the sales trends of a specific line of product.

There are numerous ways to become a "Data Scientist"
Something that many employers are not aware of is that there is more than one path to become a data scientist. Data science, after all, is an umbrella term that encapsulates other fields, such as AI, machine learning and statistics. Since the rise of popularity of data science many people try to promote themselves as a data scientist, whereas in the past they might have used a different term. Also, many people are trying to get the right education. This is one of the reasons I developed courses, such as Datalyst, to train people form all background (software dev, to no technical experience) in data science.

Understanding someones background better can also help you make better hiring and management decisions. So, in brief, these are the tribes of data scientists:

The computer Data Scientist:
This is someone who has a background in computer science. They will have done the Bachelor's in computer science, but later converted to machine learning by doing an MSc in machine learning or even a PhD. These are people who have solid technical skills, know how to code and how to use databases. They can be good all arounders and good value for money for startups that need to get good value for money. However, they lack formal training in statistics. So, this means that if you are actually facing a problem related to statistics (e.g. research design) then these are not the people for you.

The statistian Data Scientist:
These are data scientists whose training (BSc, MSc or PhD) has focused on statistics. They have a solid background in both the theory of data science and maths. They are the best people to hire for specific problems such as statistical modelling, research design, significance testing. If for example you want to develop a new methodology, let's say, for forecasting elections, then these are your people. However, in contrast to the previous category, they will probably not have much experience with machine learning or predictive modelling. If, for example, you wanted to predict bitcoin prices, you might better off going with a machine learning specialist.

The quantitative specialist Data Scientist:
These are people with background in a quantitative discipline (physics, chemistry, civil engineering or other) who decided to become data scientists because they like the field and the job prospects. It is really difficult to provide an archetype of this category, as the skills can vary widely from one candidate to the next. In my experience, it is usually physicists who make the best transition to data science. The reason is that physics is full of applied math (calculus, probability theory, linear algebra, etc.), so physicists find it easy to read through all the relevant literature. A good guide here is to try and see whether they have any projects on Github, or Kaggle, as this will demonstrate real interest in the subject.
There are many ways for someone to become a data scientist and the path they choose will determine their strengths and weaknesses. Choosing the right data scientist can be the deciding factor between growth and stagnation in a data-driven business.
