In today's world, only the smartest survive. The competitive landscape is littered with graves of well-known firms whose revenues, profits and stock prices rose for decades until they suddenly imploded. In fast-changing business environments, firms must adapt their strategies and innovate to remain at the top. But many successful firms fail to do so. Instead, they succumb to inertia, hesitate, or stick blindly to their old strategies, until it is too late. The ability to adapt to change is a measure of intelligence; so why do firms demonstrate such low Strategic IQ? What causes inertia and why is it so deadly? How can leaders help their firms to act more intelligently? This book identifies the key sources of inertia - strategic, structural and huma - and provides practical advice on how they can be overcome to create smarter corporations. It is both a wake-up call for successful firms and a lifeline for firms struggling to succeed.
