When I first met Henrik Werdelin he was a founding partner of Prehype, a "collective of entrepreneurial people who help each other build new ventures." My employer at that time had an agreement with Prehype to help us ideate and develop a new strategy for the organization's future. I always came away from those meetings with Henrik feeling both inspired and challenged; he forced us to look at our business in a completely new way.
When I learned that Henrik recently published a book called The Acorn Method: How Companies Get Growing Again, I immediately bought the e-version and started reading. I encourage you to buy a copy as well -- you won't be disappointed.
This quote from one of the first few pages provides the main concept behind the book:
I believe mature companies are like tall trees; they grow until gravity constrains them. They may shoot up rapidly, generating tiers of new branches and reaching great heights, but eventually, new growth can no longer successfully compete for resources with older branches higher up the tree.
The Acorn Method is a very quick read and, if you're like me, you'll end up with plenty of highlighted pages and notes to follow-up on. Highly recommended.
