What made businesses successful yesterday is not what will make them effective tomorrow. The most successful, and explosive growth leaders of today-and tomorrow-reflect a new competitive reality: The new competitive landscape will be shaped less by firm-specific strategies than by business ecosystems. The objective of Ralph and Sajan's book is straight-forward: to help organizations understand what business ecosystems are, what makes them different, and how to take advantage of them so that they can identify and capture new sources of value in new ways. Packed with examples and models, Topple is a pragmatic field guide that allows businesses to make sense of and take action in our changed competitive landscape and the ecosystem-centric business models that underlie it.
