Never heard of it, but seems highly relevant and well thought out. Our managers always stop at the vision and mission part, stuff some buzzwords into the soup and then offload the implementation to the team or individual. That success is following a holistic chain of events and needs attention beyond initial flag waving is not self explanatory. I will look into this more deeply and will bring it up eventually.
I was put off by the first paragraph. I'm glad I kept reading. It's hard to believe that the model is almost 40 years old and this is the first time I've seen it :(
