The recent global economic downturn has drawn CFOs into more frequent boardroom conversations and not just about forecasts, profitability and risk management but about weighty strategic and operational issues.

As a result, they are emerging with far more influence at (and exposure to) the enterprise level. Has this heightened exposure to operations and strategy, against the backdrop of an altered business world, fundamentally and permanently changed the role of the CFO?

This Criticaleye film, completed in association with IBM, tackles this question.

In this clip, one of the four speakers, Ian Tyler, the Chief Executive of Balfour Beatty plc, gives his thoughts on how the role has changed.
