I was 9 years old when my father - a strong, vibrant man in his early 40s - died of a heart attack. He was such a central figure in our lives that losing him was a terrible shock to all of us, my mother in particular.

Elected leaders in government and our men and women in uniform face a range of unprecedented challenges and pressures that demand innovative solutions.

I certainly want to continue to be a role model. But I don't think it's necessarily about being a female in our business. I think it's about... my track record, my results.

I have been in this business for over 30 years. I've seen a lot of development programmes. They don't all run smoothly.

My job is to make sure that as our customers' priorities change, as the environment changes, we shift that portfolio of products to meet them.
