Bill, a very creative and interesting way to show the difference between the tactics and the strategies in order to make clarity on what needs to be done and how. I totally agree and I have experienced that most companies complicate both these things. Also, one definitely skip to discuss or pinpoint the SMART goals. We need to derive the SMART goals and it is one of our prime responsibilities to discuss it with the company for which we are building SEO strategies.
Lastly, it's important to remember that paralysis by over-thinking is a real issue some struggle with. There's no pill for it (yet). Predicting perfection is a fool's errand. Get as close as you can within a reasonable timeframe, and prepare for future iteration. If you're traveling through your plan and determine a soft spot at any time, simply pivot. It's many hours of upfront work to get your strategy built, but it's not too hard to tweak as you go.
