Hmmm ... I can't speak to v8 as we're using v7, but my experience is there are no real "Strategies" in v7. The closest you can have are Opportunities, to track their anticipated close dates, probabilities, etc.. You can also link To-Do's to specific clients and assign them to specific people.
I can see where you might use Opportunities to cobble together something considered a "strategy", especially given the UDF's, user-defined Ratings, etc. I looked into doing something like that in another life. It depends on if you simply want to document your sales strategies and track where customers are in them (I think doable), or if you want the strategies to actually trigger actions - more of a workflow application (not doable).
