Bruce Vojak — The Hourglass Model of Breakthrough Innovation
The Innovation Show
Experiment, Iterate, Learn
Bruce describes the middle cusp where innovators prototype, test with customers, iterate, and learn.
Most companies think innovation is a straight line. Bruce Vojak spent years studying the people who prove otherwise.
Bruce Vojak is co-author of Serial Innovators: How Individuals Create and Deliver Breakthrough Innovations in Mature Firms (Oxford University Press). In this bonus episode of The Innovation Show, he joins Aidan McCullen for a focused look at the Hourglass Innovation Model — the descriptive framework that maps how serial innovators actually move from an interesting problem to a flawless product launch.
In this conversation, Bruce reveals:
- Why the Hourglass Model is descriptive, not prescriptive — and why that matters
- How serial innovators often redefine the problem before they solve it
- The Tom Osborne story — how reframing a feminine hygiene brief from diaper to garment changed everything
- Why serial innovators can appear completely unproductive for months — and why that is actually the work
- How they were practising customer empathy and design thinking before those ideas had names
- Why Execute — the stage most firms obsess over — is just one of five tasks
- How to use the model as an honest self-diagnostic: am I doing these things, or is it really the organisation?
