Recent research shows a very strong correlation between an organisation's ability to make and execute effective decisions and their organisational success. However, further research shows most organisations are not very good at decision-making with only a very small percentage of managers using decision-making best practice. Given that effective strategic decision-making and execution is probably the highest leveraged activity top management teams can undertake it is puzzling to see such a low adoption of good practices. The research outlined in this book was aimed at finding out why.
