The 2015 CIO 100 judging panel has been announced. Two women and a former leading contender in the CIO 100 join the existing panel and increase recent experience of the CIO role, business leadership and coaching skills to the already impressive judging panel of former CIOs, CEOs, advisors and technology experts that support the CIO UK editorial team.

Entering its fourth year, the CIO 100 showcases the 100 most transformative CIOs in or from the UK to demonstrate the critical role technology leaders play in modernising and improving organisations for customers and the corporation. Every year the judging panel assesses a wealth of submissions and use their own insights to draw up a list of CIOs who are enabling business change, reducing costs, increasing sustainability of the business and meeting the increasingly digital needs of customers through the use of information and technology.

While other "awards" celebrate IT estate or budget size, the CIO 100 demonstrates how CIOs work across the leadership board to create a culture of innovation, lead global change management programmes, react to changing customer needs; reduce operation inefficiency that then enables healthcare improvements, amongst many other examples.

Joining the CIO 100 judging panel for 2015 is Catherine Stagg-Macey, a leadership coach that works with a number if CIOs on how best to lead their teams and organisations. Stagg-Macey joined the CIO UK team of blog columnists in 2014 to provide her unique insights into leadership and advice on what are often described as soft skills. Her online column has proved very popular with the CIO readership. A former technology leader herself, Stagg-Macey retrained as a coach to now offer leadership coaching and facilitation.

Jayne Nickalls is former chief executive of the Cabinet Office and currently acts as a non-executive director for the Financial Services Compensation Scheme. Nickalls was in the Cabinet Office for over five years and will add strength to our ability to assess the challenges of change in the public sector.

Ian Cohen has featured prominently in the CIO 100 since it became a recognition for transformation. In a long career as a CIO Cohen has worked in quality and tabloid news at the FT and Daily Mail respectively as well as banking and financial services. His most recent role has been as CIO of insurance specialists JLT.

The existing panel of Ade McCormack, Ian Cox, Jerry Fishenden, Mike Altendorf and Richard Sykes returns to offer its expert insights as former business technology leaders. This panel supports the CIO editorial team of Mark Chillingworth and Edward Qualtrough on a daily basis.
