When you work in a particular industry over a period of time, you get specialized in that domain. For Tejesh Jayaprakash, it was application platforms, but working at a product company and overhearing coworkers talk about Big Data and the Internet of Things (IoT), Tejesh got curious. Yes, he was specialized in his field, but he was eager to learn and do more.

“I was really interested in how you capture data, analyze it and use it to make better decisions,” says Tejesh. "It was a lot of buzz back then, four years ago. That's what inspired me, that it was an emerging trend,” he says. Tejesh was ready for something different, and he knew that to move into that area, he’d have to invest in himself and get a professional certification. He knew that the certification would also help him to be confident in his knowledge. He wanted to make sure he got his training from a good training provider and hence, chose Simplilearn.

Studying Data Science on His Own

Tejesh learned about Simplilearn from one of his managers. He did the online ITIL® Foundation course because it was required by his employer, but while browsing through other courses, he found data science. “At that time, I wanted to learn more about it so I actually enrolled for that one as well.” Tejesh was engaged enough with the material to get through the course quickly. “I did it in about eight weeks, spending two to three hours every day,” he says.

Tejesh took the Data Scientist course in 2015. “I'm currently working on supply chain planning side,” he says, “so the planning stage involves a lot of data analysis and forecasting and predictive analysis. And now I understand the concept of the software.” Tejesh says this learning has helped him get a broader understanding of how to analyze data to make sense of it and predict how data will behave in the future. “It gave me a very good understanding as to how you plan things and how the algorithm works, and how the regression modeling and other statistical modeling work,” he says. 

Of the course, Tejesh says, “I liked the structure of the course because it starts with how you analyze data, generate data models and how you forecast using these models." Besides, you have three different tools to learn: R, SAS, and Excel. The course teaches in detail how to use R and SAS software, and how to use them within Excel. “I got step-by-step instructions as to how I could perform things and what I have to be looking for and what the additional options are that I have within each software,” he says. About R, he says it has become something you must know if you want to be a data analyst. “I use it in daily work”, he adds.

For Tejesh, however, learning business analytics with Excel was the most important because it is used by everyone, and by almost every organization. “Even the planning tool that we use is Excel on the front end and SAP on the back end,” he explains. 

Learning how to use Excel for data analytics was very helpful for Tejesh. “I never knew there was an option for enabling a data analytics tab and then you can do many other things rather than just adding and subtracting in Excel,” he says. “I use it daily to calculate a regression model or confidence interval. I just go into the data analytics tab then get my data and then I can actually tell you how you could build a model based on the tables.” 

In addition to the quality of the course material and the knowledge he gained, Tejesh appreciated the customer support he got with Simplilearn. “The customer support was really helpful when I had issues”, he says. He also added that he received good feedback on his assignments and advice for improvement. “I found that very supportive and very accommodating,” says Tejesh. "And cost wise also it's very reasonable. You get good value for your money,” he adds. 

Understanding the Concepts Behind the Software

“After completing the certification, now if you ask me how to do a regression model using a couple of variables, I can do it to in Excel,” says Tejesh, which he likes because the regression model is one of the most commonly used models for predictive analytics. A lot of software can now do things automatically once you have the data, but Tejesh likes understanding the concepts behind the software. “It's not just about having data and the output, but how the software arrived at this output,” he says.

Tejesh was working as a senior software engineer in SAP and now he works as a technology consultant. “In my previous company, I was developing system landscapes for product development and improving operational efficiencies within the landscapes and doing the day-to-day monitoring like upgrades. It was more technical.” Today, Tejesh’s job is more about how a planning tool would help a customer optimize their supply chain. “It's an end-to-end that we are implementing that helps customers analyze promotions, marketing and everything and how that would impact their supply, their finance, and everything. It's an integration of demand-supply and finance,” he explains.

Taking the Initiative Leads to Success 

When asked if he has advice for others considering a certification, Tejesh says, “If you are interested in learning more and your company doesn't offer opportunities to learn because you are specialized in a skill set, invest in something else that you want to learn on your own.” 

For Tejesh, “This certification is like a feather in my cap because I now have an understanding of data analytics.”

Tejesh resides in Sydney, Australia and has been interacting with interconnected consumer-relevant industries. The certification has helped him in his workplace where he could review and analyze the client’s business operations and processes recommending improvements.

“Like I said, in technology if you work for a particular period of time in one area, you get specialized in that one particular field,” says Tejesh. “I wanted to get knowledge in other fields as well like analytics.” He adds, “That's the reason I did the course with Simplilearn, and now I've actually moved into that field. It's definitely a success story!”
