This week's edition of The Bottom Line, hosted by Evan Davis on Radio 4, is about business turnarounds. The three guests this week have all been involved in rescuing companies and they share their experiences, in which the culture of the organisation feature heavily. For those who are picking up on the tutor2u 10 companies to study, it is particularly useful as the first of these is Adam Crozier, Chief Executive of ITV (and former CEO of Royal Mail). Different scale is offered by James Eden, Chief Executive and owner of clothing brand Private White VC, and Nick Sanders, Head of Portfolio at private equity firm Better Capital. Well worth getting students to listen and to write some compare-and-contrast notes.
