The 21st century has witnessed an age for Organisations to follow the flow of the technological pragmatic shift from manual to automation of their business processes, procedures and activities. As a result, organisations are being driven towards the technological frontier in the opportunity to acquire more new customers and attain a competitive advantage over their competitors.
