Paul Cossell, CEO of ISG, said: “Instead of waiting for new incumbents to disrupt our industry, ISG has used its 30 years’ experience as a market leader to tackle the productivity and cyclical financial issues that have plagued our industry for too long.

“Traditional operating practices and central command structures do not work in our dynamic society or for agile global customers, so we have embraced change, empower our people to be creative and encourage radical thinking, with technology and innovation at our core.

“What’s clear is that ripping up the old rule book and learning from our tech-led customers has proved transformational for our business.

“Our people are already generating the ideas and innovation that are proving instrumental in moving our industry forward.

“From the launch of a new Level 3 qualification, to developing a standard component design for classrooms, or our very first filed patent for in-house developed technology, it is the quality of our people and the supportive structure around them that sets our business apart.”
