According to IDC, global IT services and business service revenues total $502 billion in H2 2017-- a 3.6% Y-o-Y increase. Services revenue for full year 2017 total "just shy" of $1 trillion, a 4% increase over 2016.
W. Europe is the 2nd largest global market, even if H2 2017 growth clocks at just 1% Y-o-Y. The emerging CEE and MEA markets are much healthier, showing 7% Y-o-Y growth, even if they remain relatively small. However the size allows a few large IT initiatives to drive up growth, and the fact organisations have fewer IT assets makes adoption of digital services "much easier."
The growth of services revenues slightly outpaces the global GDP growth rate, reflecting a brighter economic outlook, a shared urgency for large-scale digital transformation and, in some segments, new digital services offsetting the commoditisation of traditional services.
