Scaling Up by Verne Harnish
I believe the Scaling Up content is great for more mature teams: teams that have many of the "basics" down. If you are a business owner and are really a "practitioner" who is now so successful that you're "running a business" but you don't know what to do next, I would suggest that you start with Traction/EOS. Once you get those fundamentals down, you can add in some of the Scaling Up tools.
Of course, opinions vary. You could pick up Scaling Up and have it just work for you. You may also choose to engage a consultant from the Gazelles organization and have great success. We hope you do!
If you are like most companies, you may find that you want to pick and choose the best tools for your team.
If you want to learn about Scaling Up, head over to gazelles.com. They have lots of great content freely available. You can also learn about conferences and other events they provide.
The encouragework platform brings in key concepts from Scaling Up, including document templates for many of their tools and a place for you to manage any other planning documents you might prefer.
