"The act of modularizing your product is the very act of inviting your future competitors into existence."
Carliss Baldwin and Kim Clark, authors of the landmark Design Rules: The Power of Modularity, join Aidan McCullen for an Innovation Show exclusive. Their book is the Rosetta Stone of platform strategy — the mechanic underneath the Innovator's Dilemma — and it has never been more relevant than in this age of AI.
In this conversation, Carliss and Kim reveal:
- Why the power of modularity underpins Moore's Law — and everything digital around us
- How IBM engineers, locked in a Connecticut motel before Christmas, invented the first conscious modular platform strategy
- How the System/360 turned IBM from a competitor into "the environment"
- Why the engineers who walked out of IBM's San Jose plant spawned the entire disk-drive industry
- How IBM owned 30% of Intel and contracted Microsoft — yet failed to own the only two sources of profit in the PC ecosystem
- Why "the game is never incontestably won"
- Why Sears couldn't become Walmart, and Walmart couldn't become Amazon
- The Chevy Vega that shook itself apart on the test track — and the cost of losing tacit knowledge
- Why AI agents are forcing companies to map their workflows for the first time
- How Haier replaced twelve layers of management with 4,000 entrepreneurial teams
- Why leadership is the operating system of the organisation
