QUE.5 Sanchit, after completing his entrepreneurship course from Sweden returned to India and started a coffee shop ‘AromaCoffeeCan’ in a famous mall in New Delhi. The speciality of the coffee ship was the special aroma of coffee and a wide variety of flavours to choose from. Somehow, the business was neither profitable nor popular. Sanchit was keen to find out the reason. He appointed Sandhya, an MBA from a reputed college, as a Manager to find out the causes for the same.Sandhya took feedback from the clients and found out that though they loved the special unique aroma of coffee but were not happy with the long waiting time being taken to process the order. She analysed and found out that there were many unnecessary obstructions in between which could be eliminated. She fixed a standard time for processing the order.She also realised that there were some flavours whose demand was not enough. So, she also decided to stop the sale of such flavours. As a result with in a short period Sandhya was able to attract the customers.Identify and explain any two techniques of scientific management used by Sandhya to solve the problem.
