Business Process Outsourcing (BPO) is the practice of hiring or contracting a firm to perform specific tasks that are directly related to the workings of a company. Application development services are extremely popular in today’s world because the paradigm of traditional advertisement is changing. Nowadays companies focus more and spend more on developing unique mobile applications for their businesses that can actively become part of daily life of a person through his or her cellphone, rather than spend significant amount of money to advertise its products through commercials on the television.
