Jack McCullough, President of the CFO Leadership Council, is back on CFO 4.0 to sit with Hannah to talk about the idea that every organisation has quiet specialists - rarely high on the org chart, rarely natural leaders who are so irreplaceable that losing them would do more damage than losing a member of the C-suite.

Jack introduces his new book "The Rodman Paradox". Borrowing his title from NBA legend Dennis Rodman (a specialist who never scored much but became, by some measures, the greatest winner in basketball history)

In this conversation, Jack and Hannah dig into:

• Why traditional org charts fail to capture who really holds a company together
• How to spot your own "Rodmans" using organisational network analysis
• Why promoting a Rodman is often the worst thing you can do for them (and for the business)
• How to recognise and reward specialists who don't want titles, meetings, or management responsibility
• Real stories from the book
