Kallasvuo, a lawyer, was CFO of Nokia before becoming CEO.
Under his tenure as CEO, Nokia "hired a large number of executives who knew little about mobile technology, media and design," says the book.

Stephen Elop completed the collapse of the iconic Finnish company appartently predicting that he would be seen as a double-agent for Microsoft from where he came to head up Nokia and where he returned after selling the company to Microsoft.
This is a fascinating account of an epic disaster which makes you realise how staggeringly stupid top management can be when it isolates itself from the detail of the business it's in.
