Digital transformation is the process of using digital technologies to create new — or modify existing — business processes, culture,and customer experiences to meet changing business and market requirements. This reimagining of business in the digital age is digital transformation.

It transcends traditional roles like sales, marketing, and customer service. Instead, digital transformation begins and ends with how you think about, and engage with, customers.  As we move from paper to spreadsheets to smart applications for managing our business, we have the chance to reimagine how we do business — how we engage our customers — with digital technology on our side.

 IT Professional Services can be defined as the delivery of technology-related services to a customer, allowing them to focus on their core business concerns. Services can range from consulting and advising on strategy to project management and data analytics.
