The blue ocean strategy in my opinion is in the top 3 books references in corporate strategy. His reading is fluid and inspiring. Its content is in line with today's world (technology change, societal, global ...). The method will allow you to advance to the virgin market competition ... you write the rules! At the end of his reading you'll want; try it for your own account. Even if business illustrations in the book are often large companies, the method also works for small and very small, whether in BtB or BtC. Of course this will require adaptations.
