Analytics is a field which combines data, information technology, statistical analysis, quantitative methods and computer-based models into one to improve the business decisions. We may feel complicated about this subject but Mr. Perumal Kumar who is a business analytics and consulting leader made it easy to get a basic knowledge about it to ISBR students. On Feb 6,2021 he conducted a guest lecture on Business Analytics and Optimization with Industry cases in online zoom platform. The practical approach in his explanation made it clear to get the hang of the subject. He explained about the business analytics concept along with the different stages giving an example for each. We learnt the applications on various sectors like finance, marketing, hospitals, HR and operations with more practical insights. HR use case on Attrition Prediction and Marketing/Retail Analytics Use case on inventory management were explained to the students. The session was on the whole clear and easy for the students to understand the analytics and the various applications of it in different sectors.
