A business plan and a strategy are not the same thing.
Strategy is the vision, the motivation, the ‘why’. Planning is the detail, the mechanism, the ‘how’.
Strategy sets out where you want to be. Planning gives you the map to get there.
Strategy sets out your thinking. Planning unpacks it.
Although the terms are often used interchangeably, the distinction is important. Strategy is your identity. Planning is how you reveal it.
