I recommend using the vivid vision technique to clarify your product’s vision. You are welcome to try others. The reason why I recommend this versus a simple statement is that this allows you to align your team extremely descriptively on every aspect on how you will work together over three years. It sounds ridiculous but why leave it up to chance? You can see a modified version of what I wrote for my internal team here. A personal oversight I realize now is that I did not describe the team dynamics. Until much later on did I start describing my team as high performing and held to high standards and expectations.
