Worldwide Services Revenue Crossed $1 Trillion Mark in 2018

Worldwide revenues for IT Services and Business Services totaled $513 billion in the second half of 2018 (2H18), an increase of 4.5% year over year (in constant currency), according to IDC. For the entire year, revenues crossed the $1 trillion mark in 2018. Annual growth accelerated slightly to 4.3%, outstripping the worldwide GDP growth by more than half a percentage point. This largely reflects overall healthy corporate IT spending sustained by large enterprises' cautious yet optimistic business outlook.

Looking at different services markets, project-oriented revenues (i.e. consulting, integration, application development, etc.) continued to outpace outsourcing and support & training. They grew by 6.4% year over year in 2H18 to $194 billion and 5.8% to $380 billion for the entire year. The growth was led largely by business consulting and application development markets. Business consulting grew 9.1% to $63 billion in 2H18 and 8.3% to $123 billion for the year. Custom application development (CAD) grew 8.3% to almost $24 billion in 2H18 and 7.5% to $46 billion for 2018 (compared with only 5.1% in 2017).

In managed services, revenues grew 3.8% to $240 million in 2H18 and 3.6% to $473 million for 2018, which is on par with real worldwide GDP growth. Application-related managed services revenues (hosted and on-premise application management) outpaced infrastructure and business process outsourcing (BPO), growing by 5.8% to $41 billion in 2H18 and 5.6% to $80 billion for 2018. IDC expects application-related managed services to continue to out perform other outsourcing segments. IT Outsourcing (ITO) continued to decline due to flat or negative growth in the mature geographic markets. This was offset somewhat by moderate growth in horizontal business process outsourcing (BPO).

On a geographic basis, the United States, the largest services market, grew by 4.8% to $233 million in 2H18 and 4.6% to $459 million for 2018, a moderate acceleration. Western Europe, the second largest market, grew by almost 3% to $266 billion for 2018, much slower than the U.S. but in-line with IDC's previous estimate and more than twice as fast as real GDP growth for the region. Asia/Pacific (excluding Japan) (APeJ) growth cooled slightly to 6.2% with revenues of $110 billion, partially reflecting economic angst over the impending trade war between the U.S. and China, and the economic slow-down in key mature markets (i.e. Australia/New Zealand, South Korea). Japan enjoyed a slight growth uptick, as business results from the major Japanese services vendors posted slightly higher than expected in 2H18, mainly due to continuing demands for system renewal. In other emerging markets, both Latin America and Central & Eastern Europe (CEE) saw faster growth in 2018 than the previous year.

"Steady growth in the services markets are driven by a continued demand for digital solutions across the regions with the Americas continuing to contribute to the bulk of the revenue growth," said Lisa Nagamine, research manager, IDC's Worldwide Semiannual Services Tracker. "2018 surpassed the trillion-dollar mark, as we had forecasted at the end of 2017. We expect future growth in many geographies worldwide in coming years.
