"Innovation" is just a fancy word for "breaking with historic inertia to rethink how things are done through the lens of modern conditions, sensibilities and technologies - at speed and at scale"
It requires just a few things
1. First principles thinking
2. Lateral thinking
3. Optimism over fear
It shouldn't just be done in a lab or in a skunkworks - it should be done by every employee, in every department, every day.
