An MBA’s guide to understanding Data Science

If you come from a non-technical background, it is easy to feel insecure with heavy buzzwords around data science. Do not let that concern overshadow all that you can bring to the table. A business-savvy tech person or a technically-sound business person is an asset to any organization.

To oversimplify it,

“Data science is the discipline of making data useful.”

If you are wondering why you should care about these terms, we present to you some facts.

  1. The big data analytics market is expected to touch $103 billion by 2023.
  2. In 2020, an individual will generate 1.7 MBs in a second.
  3. Users on internet generate about 2.5 quintillion bytes of data each day.
  4. 95% of businesses acknowledge the need to manage unstructured data as a challenge for their business.
  5. 97.2% of organizations are investing in big data and AI.
  6. Using big data analytics, Netflix saves $1 billion per year on customer retention. [1]
  7. In 2020, there will be around 40 trillion gigabytes of data (40 zettabytes)

Organisations are extensively hiring data scientists and machine learning engineers for an analytical transformation within the various verticals to keep up with ever changing and rapid data generating world.

“You can’t manage what you don’t measure.” — Peter Drucker

There is also a high demand for business translators or those who can serve as a link between data analysts and practical applications and solutions to an organization’s business challenges.

Increasing number of organizations are on the hunt for these translators who not only possess data savviness but who can also deeply embed themselves into the organization’s decision-making processes. McKinsey & Company estimated the demand for translators will reach 2 to 4 million in the United States alone over the next decade.

Businesses are swimming in data of customer behavior, competitors, and their operations. The need for managers who can sail through the data and uncover insights that would generate profit is why data science positions are some of the most in-demand and highest paying jobs around.[2]
