According to an IT Market Model by Statista, the expenditure on the global IT services market is expected to reach $853 billion by 2021, up from $737 billion in 2017. North America is the largest growing market for IT services due to the presence of a robust IT infrastructure. The IT services market is expected to register a compound annual growth rate (CAGR) of approximately 8.87% during the forecasted period (2020-2025). The key reason for this economic development for this sector is the increased demand for apps and social media channels such as Google Hangouts, WhatsApp Video Call, Zoom, and Microsoft Teams. Due to coronavirus, many opportunities have been opened up in the IT industry, such as the growing need for 5th generation (5G) technology. As a result of the pandemic, remote interaction has become a top priority for many organizations. Remote interaction would not only benefit companies from imposing remote work. Telemedicine is one of the emerging industries during the COVID-19 recession. This could help patients to get diagnosed and treated without a doctor's need to be physically present.

There is no doubt the COVID-19 has greatly affected many businesses around the world and the IT service industry is not exempted from it. As a result, global IT leaders reset their plans in the short term to withstand the uncertainty. Accenture is one of the most renowned IT service companies in the world. In the middle of the pandemic, Accenture developed an operating model that harnesses modern and emerging technologies to constantly push the limits of today's systems and business models, including artificial intelligence, distributed ledger technology, and quantum computing.
