In 2020, I'm willing to bet that there is already a good template in existence to help you and your team solve a problem.
Often though, it can be hard to find them, so I've put together a quick list of ones I've found to help you stop deciding how to solve your problem, and just start solving it!
We use a design sprint when we want to start solving a problem, as a team - fast.
Culture doesn't happen by accident, It is designed.
Taking the best of the world’s problem-solving processes (Design Thinking/Gamestorming/Design Sprints/Agile) and crushing them down to their absolute essence to help you and your team solve problems. Good to use for a team retrospective too.
I've found using Mural for strategy to be absolutely incredible. I don't see any plan as "set." The more you build, measure and learn, the more likely you need to adapt. Keeping strategy in an easily-updatable format I find is key.
If you can't ban them, then at least run them well.
Start, energise and end well, with one of these activities.
