Strategy can be a little complicated but we've simplified it for you so that you and your team will be set up to execute together. Strategy is 'how' you will achieve your vision and it's another opportunity to pull your team together to get things done.
Think of your goal as the top of the mountain and the purpose as the star above that guides you. The strategy is your chosen path. There are many ways to get to the top – the key is to choose a path and make sure the whole team knows what it is and sticks to the path. It’s easy for people to get separated so everyone should have a role. You would not send marketing up one way and sales up the other so avoid ‘functional strategies’ – make the cross-functional.
