The rise and fall of RIM.
RIM rode technology disruption and created a company with $20 billion/year in revenue only to see it disappear by being disrupted themselves.
Lots of lessons here.
1) Even though the CEOs were reading the "Innovators Dilemma" they still had little perspective on how rapid disruption would happen to them. And even less of an understanding what to do about it. (The attempt to integrate the QNX software into existing products is a cautionary tale of technical debt, refactoring and plain bad engineering management.) The iPhone in 2007 should have been a wake-up call to both CEOs. Yet they both fell prey to the classic "disruption always looks like a toy to the incumbents" mistake.
2) The company grew past the management skills of the founders. The insular nature of the founders, the Canadian entrepreneurial ecosystem, founder hubris and a feckless board ended any potential of a positive intervention. It took a complete meltdown to get the board to act.
3) Mike Lazaridis, the technical CEO, fell prey to the "shiny object" syndrome. He discovered new technology (QNX) that he thought obsoleted the current software that drove the Blackberry handsets (Java). But instead of figuring out how to finesse the transition, he literally abandoned the existing development team (and revenue). A great example of how not to manage a technology transition.
3) Dealing with major platform disruption usually takes radical structural changes, not new product features. The story unfolds as a slow motion car crash as the CEOs waited, way, way too long to recognize, let alone deal with it. There's a reason that turnaround CEO's downsize companies and focus on what's important. If you're the founder it's almost impossible to get rid of your favorite projects.
Only quibble others have noted. The book barely mentions the changes Heins made, and almost nothing about Chens strategy.
A great business book.
