Strategy vs. planning
A strategy is a set of choices about what to do AND what not to do. A plan is the sequence of activities that follows from the choices. The difference is the no.
You can tell which one you have by looking at the document. If it lists everything the company should do — every market to enter, every product to launch, every customer to win — it's a plan. If it lists what the company is going to stop doing, the markets it's going to leave, the customers it's going to ignore, the products it's going to kill, the bets it's not going to make — that's a strategy.
A strategy without a no is a marketing brochure.
