How to not screw up your product strategy

I think this is a beautifully written article. There might be a lot of gems to learn from here. One thing makes me a bit sceptic though:

"Clear your schedule, and read this book"

I haven't been around many years in the private sector, and haven't sold much. But I sometimes have a feeling, many project-strategies are kind of over-engineered and so meticulously thought through, that no actual work happens. This seems like an anti-pattern for achieving things to me.

"Third, talk to a lot of people" however really resonates with me, because if there is one thing I see all the time with successful new products in my field, is that they have built very strong communication channels with users and people interested in the product.
