“You can’t Improve what you Don’t Measure” - Peter Drucker
The tech industry is marked by continuous ups and downs. Amidst this upheaval, the significance of Data in defining career opportunities is undebatable. Job roles surrounding Data Management are selling like hot cakes. Even among these roles, there are some which are considered to be slightly more coveted in terms of their demand, career prospects and the remuneration they attract. One such role is that of a Data Scientist. Consequently, it is important to understand the transition route which one might opt for from different positions like that of a Data Analyst to Data Scientist, from a Business Analyst to Data Scientist and so on.
In this blog, we shall try and answer the question of how to go from Data Analyst to Data Scientist. Before seeking to understand the transition from Data Analyst to Data Scientist, we shall take a synoptic view of the difference between the two career positions. Additionally, we shall look at the career transition from Business Analyst to Data Scientist.
Data Analyst vs. Data Scientist
Before delving into the question of how to move from Data Analyst to Data Scientist, it is important to understand the difference between the two career positions. This is especially because there is considerable overlap between the different job roles as they happen to be concerned with Data in difference ways. Firstly, a Data Scientist happens to possess skills which are considered to be more advanced than that of a Data Analyst. Let us try to understand the two positions in this way: a business firm makes and sells baby cardigans. It was consequently noticed that parents who came to buy the cardigans, often enquired about matching booties for their little ones. When you share this finding with the marketing team of the firm, you are largely working in the capacity of a Data Analyst. However, if you happen to go a step further and build a recommendation algorithm systems which recommends matching booties for cardigans for the small ones, you are largely working in the capacity of a Data Scientist.
Having said that, the two positions can be accepted as being complementary to each other. This is especially because there are a number of arenas wherein their roles overlap. However, the divergence is essentially at the point of the two possessing different levels of coding/programming expertise.

In many cases, some of the requirements might be desirable, but not mandatory. Hence, it is important to apply and keep striving even in the face of rejection which helps you in learning a whole lot of new things about what more is expected of you as a budding Data Scientist.
Business Analyst vs. Data Scientist
Business Analysts make use of data for undertaking important business decisions. They are engaged in seeking innovative solutions to existing business problems. They monitor and evaluate the efficiency of business processes and expenses as well as communicate the findings to relevant stakeholders. They develop business strategies, procedures and arrangements.
Having discussed the above definition of a Business Analyst, you can well understand that a Business Analyst happens to be single-mindedly concerned with drawing up and interpreting reports on the day to day operations of a business and accordingly provide recommendations on the same. In contrast, a Data Scientist, writes complex algorithms and computer programming and thus is an expert in high-end data manipulation.
While Business Analysts act as a channel of communication between clients and the business; Data Scientist remain concerned with modeling and analyzing data.
