A pioneering strategy management professional, Bjarte Bogsnes holds the unique distinction of being the only person to have "blown up the budget" at more than one company: at his previous employer, the European plastics manufacturer Borealis, and at his current one, Statoil, the Norwegian oil giant. Now he wants to blow up the calendar, too—calling it an arbitrary (and anachronistic) basis for forecasting. A dedicated champion of the Beyond Budgeting movement, Bogsnes takes the concept of rolling forecasting—itself a relatively new approach—one big step further, with dynamic forecasting.
