"I just ran a FIRO-B session for a somewhat large group (40) of finance professionals. I found that the background and context that Bob taught was great for starting the discussion. The client group gave me wonderful feedback about how they were able to move quickly from personal insights to seeing the real business impacts of the way they were working together. They were then in a really good position to talk together about how they want to improve."Lisa Stewart
