Adrian Barnard has stepped down as CEO of The Change Organisation after successfully completing his brief in just three financial quarters.
He joined The Change in May 2016 with a brief to increase sales margins and re-shape the sales structure of the company.
The move allows Barnard to focus on new projects, including a comms industry venture launching in the coming months and a new business in legal sector.
Chairman and founder of The Change, Graham Burns, said: "We appreciate greatly what Adrian has done for the Change during his tenure as CEO.
"We shall miss his energy, commercial experience and invaluable insights on the ICT industry."
Barnard added: "I've learnt a lot about a new area in the technology sector and I'm heartened that I've been able to make positive changes and deliver value."
