What Next?

Data science has created a buzz all over the world. It is a stream that deals with analyzing, modeling, and generating data, and deriving meaningful insights and information from this data. The data available to us today is increasing rapidly due to the increase in digitization. Organisations have realized the potential of data and the urgency to analyze this data to gain valuable insights from the same. 

To help an organization convert this potential data into a real opportunity, organisations require skilled professionals such as data engineers, data scientists, and AI engineers. Data scientists can mutually benefit from this since they can enhance their skills and knowledge while turning data into real-world success. 

Shortage of Skilled Resources

The US will face a shortage of close to 190,000 Data Scientists and 1.5 million managers and analysts, suggests a study by McKinsey Global Institute. There is a high demand for data scientists in India too. Technologies and tools have been introduced, but there is a gap in the number of skilled professionals available to take up these jobs and work on these tools. The co-founder and CEO of Fractal Analytics, Srikanth Velamakanni, states that there are two types of talent deficits. There are data scientists who do not have analytical skills or there are analysts who do not know how to appropriately use data. The demand for skilled professionals in these job roles is in high demand. 

Exploiting the Power of Data

One of the main reasons why data scientists are in high demand is due to the growing potential of gathering data from the physical world. With 5G and other such networks that are coming up, digitization across all industries is growing. 5G is expanding and will also be helpful in bringing information to the supporting engineers and operators. Data that was previously available and accessible only on work PCs can now easily be streamed on the shop floor. 

There are similar trends across different industries. For example, in the healthcare industry, there are more connectivity and data-collection capabilities when compared to ever before. This creates an unprecedented opportunity for Data Science to flourish. https://www.youtube.com/embed/I-_leVrSMlw?feature=oembed

A Plethora of Job Roles

While Data Science is a broad topic under which there are several smaller and well-defined areas, there are a number of jobs that you can take up. Some of these job roles are a data analyst, data scientist, business analyst, database administrator, and analytics manager. 

There is quite a lot of difference between working in universities and educational institutions and working on real-time projects and case studies. Testing and training your machine learning models on data sets are completely different from performing any research. The input is known as data, and the output depends on the precision and accuracy of this data. Academic research is the backbone of the applications we use on a daily basis. However, in real-world applications and tools that are being used every day, many challenges do come up. It may be difficult to gather data. The data may not exist, and a Data Scientist would have to work with several different database engineers to create the perfect machine learning models to be trained and tested.

Post Graduate Program in Data Science & Business Analytics or PGP-DSBA is a course offered by the McCombs School of Business at The University of Texas at Austin and delivered to you by Great Learning. The PGP- DSBA is a top business analytics program and will teach you a comprehensive curriculum that covers the most widely used tools and techniques in the world of Data Science and Analytics.

Benefits of a Data Science Career?

The demand for data science skills has skyrocketed, this is due to the numerous amounts of data that is getting generated across the businesses and the need for effective data-driven decision making.

High Salary

Work experience is the largest factor in data science salaries; however, the average salary of an entry-level data science professional is higher than the median salary in the U.S. 

Solve Complex Problems

The primary job of a data science professional is to find insights by analyzing and processing a huge amount of raw data. Example: How to increase sales? To identify the hidden problems in current business operations.

Being able to extract information from data is a very powerful position to be in with data being collected in all aspects of society, ranging from marketing to health and even to sports and entertainment.” 

Less Vulnerable to Job Automation

In general, the more specialized the job (fewer workers are Doing It), the less likely it is to be automated because there is less incentive to invest the resources needed to build a machine capable of the job.

At that point, data science will be an essential skill, but one not limited to a handful of experts, and we will not need anyone trained specifically in data science. I am hopeful for this time because I have repeatedly seen the importance of domain expertise for building effective data science pipelines. If we can put the right tools in the hands of those with experience in a field, then data science can deliver on its promises of increasing efficiency and enabling objective decisions. Automation is not likely to take data science jobs, but if the right tools are developed, a data scientist may become an extraneous specialization.

Individuals who have extensive knowledge on how to convert data into actionable insights using analytical skills are the ones who have a chance to have a bright career in data science.

Choose a Language/tool

This is probably the most asked question by beginners. Which language/ tool should I choose to excel in a career in data science?
