Ministry of Defence chief digital and information officer Mike Stone has become the latest high-profile departure at the top of the Civil Service after quitting his role.
His move follows a series of departures at the Government Digital Service as departments and the Cabinet Office tussle for control of IT across Whitehall.
Stone resigned, according to the MoD, and has provided the six months' notice required under his contract. It is expected that he will work out his contract.
Stone has been in his position at the MoD for just two years. He was charged with transforming IT for the 40,000 or so civil servants in the department and the armed forces that they serve.
Stone outlined his transformation plans at Splunk's .conf2016 annual user conference last month. These included rolling out applications in the cloud via a private instance of Microsoft Azure, including an Office 365 rollout.
The MoD is poised to roll out a series of new platforms and tools intended to make better use of information. Analytics software would form part of this.
"The power of the cloud, mobility, social media and especially platforms, particularly platform economics, is what I'm seeking to exploit. What I want to do is to ensure that we're providing to servicemen and civil servants the kinds of capabilities that are 'of the moment', if not better than what they can get at home," said Stone.
Stone spent 28 years in the Army, rising to the rank of brigadier and serving as the Army's CIO and, before that, as the IT director for the Field HQ. His experience included tours of Northern Ireland, Germany, Cyprus and Kenya.
After serving in the Army, Stone worked at Indian outsourcing company Mastek as chief client officer before becoming CEO of the Defence Business Services at hospitality company DBS.
