"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
