The rise in mobile-phone usage and decline in data costs will add 500 million new internet users in India over the next five years creating opportunities for new businesses. The monthly data usage per smartphone in India is expected to increase from 3.9 GB in 2017 to 18 GB by 2023. With such a grand scenario, the competition between the telecom giants is fierce. Companies are finding ways to stay at the top and gain profits. In such a scenario Lean Six Sigma (LSS) can aid the companies in their ventures.
