Bruce Vojak — The Hourglass Model of Breakthrough Innovation
The Innovation Show
Nonlinear Flow and State Diagram
Bruce emphasizes the model's nonlinearity: innovators move between five states rather than follow a strict sequence.
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?
