Try to go beyond hand waving and opinions and find out what really is happening. A good way to start is to ask people to picture what their scenario would look like if everything was perfect. This puts them into a positive frame and helps focus on great outcomes. Once you’re sure you’re working on an improvement opportunity that’s worth your time, try small time-bound experiments that you actually follow through on. Use what you learn to come up with the next step. I’ve found that the combination of being bold with the vision but taking small steps to get there is a good combination.
