How many people work in your IT department?

What percentage of annual turnover does IT represent?
3 per cent

What is the basic structure of your IT department?
There are four core teams – architecture, service delivery, projects and business solutions. The structure is based on a small internal team of around 20 and we utilise an outsourced services-based model.

Who are your key suppliers?
Logica for service desk and apps supportComputacentre for desktop services; BAA is a supplier for infrastructure, networks and 70% of our current applications. We are currently negotiating our own outsource deals.

Who has been the most influential people in your career?
Tanya Howarth, who brought me into IT and Dr Lillian Lodge, who coached and mentored me through my senior roles.

Do you believe in mentoring?
Coaching has been fundamental to my being successful. I continue to use Dr Lodge for support on a regular basis. Even as a more junior manager, coaching has been a major help. In terms of education, I have done a distance-learning MBA through Warwick University. Without this I would not have progressed from an engineer to a senior IT role. It gives the language and structure of business decision making.

Which tools or tactics have given you most success in communicating up, down or across? 
Regular face-to-face communications. With the team it is being available in an open-plan office, walking the floor and standing up in front of the whole team on a regular basis for updates. With peers and upwards it is again face to face. This builds a relationship which brings trust and support. You cannot do this with memos.

What has been your greatest success?
As an engineer, in my earlier career, creating and setting up the new Walkers crisps factory in Leicester. In IT terms, it was building the current team at Gatwick which has rapidly formed into a high performance team delivering massive value.

How do you keep up to date with the march of technology?
Networking, web sites, press and most importantly, tapping into the wealth of experience working in my current team. They do a great job of educating me and stop me getting too excited about the latest fad.

How do you deal with stress?
To cope, I do a lot of mountain biking. The trails of West Berkshire are a hidden gem and for real adrenalin I had four days on the bike in Chamonix this summer.

Which word or phrase do you most use/overuse?
Basically (according to my wife!)
Which business books have been influential in your career?
As an engineer, then Skunk works is hard to beat. It is the story of the Chief engineer at the Lockheed secret development centre responsible for stealth technology, the U2 and Blackbird spy plane.

What else do you do outside of work?
The last couple of years I have been learning to sail
