The volume of data flowing into organizations is on the rise, and exponentially so. Organizations have come to realize that this is a potential source of great insights to guide their future course of action, which is why big data has become very important in recent years.
The big data industry has shown immense growth in recent years, driven by executives across industries realizing the value it can deliver. From healthcare to marketing and technology, scarce is the organization that cannot derive value by sifting through its data. This growth has got a further push from the rise of digital platforms and technologies, facilitating the availability of information that big data professionals at organizations can mine to gauge useful insights.
There are a number of ways in which big data can help organizations, and some of these are listed below:
- Availability of sophisticated data-based analysis
- Developing sophisticated business strategies
- Improving toplines and bottom lines
There is strong demand for skilled professionals.
It follows logically that the demand for skilled big data professionals is rising. However, the growth in job openings far outstrips that in availability of suitable talent. The growth in big data means the demand is likely to stay strong in the foreseeable future.
The gap comes about due to the rapid growth of digital platforms and technologies and the consequent upsurge in data availability. Data storage no longer is a concern, and the focus is now on finding enough skilled people to deal with the challenge of pulling out productive insights from large amounts of complex data. According to Analytics Insight, India will see 1.5 lakh new data science job openings by 2020, an increase of about 62% compared to 2019. About 70% of the present job openings are for data scientists with under five years of work experience.
