About the author

Kept short on purpose

Risto Siilasmaa founded F-Secure, chaired it for over three decades, and chaired Nokia through its 2012–2020 transformation — a decade of sitting where the OTA loop either runs or breaks. Observe, Think, Act is his attempt to turn that experience, tested against two hundred scored cases, into something other leaders can use.

The shortest way to understand his argument is not this paragraph — it is the framework and the research behind it.
