How do you decide what the basics are? maybe you should outsource answering customer emails instead of spending time doing them yourself? The basics is not a differentiator; strategy is. At best the basics is just a fitness measure of strategy. "Can I still do all the essential non-functional stuff, I must do, whilst pursuing my most valued goals?"

Strategy is about choosing how to achieve a goal, all the tactics, fitness measures/metrics, compromises, challenges to overcome but it's also the goal itself. Strategy should guide you, your tactics at play to deliver your ultimate goal. Execution is just doing that stuff hopefully focussing on the stuff that matters most.
