#6b: Mission, vision, and strategy.
Mission is the "what" of your organisation, vision the "why", and strategy the "how".
Mission is what your organisation will achieve. Vision is why that mission matters. It's why people should feel motivated to be part of the mission. Like mission, vision is aspirational. Yet vision is also often connected to an organisation's values.
Strategy is how you achieve your mission. It's how decisions will be made along the way. While your strategy may not present all the answers, it provides clear guidance on how to deal with the inevitable trade-offs and difficult questions. What do you won't do is as much a part of strategy as what you will.
