BOS / ROS Isn't a Strategy
This could be a few things but, strategy, really?
It's a process at best either, deliberate (ROS) or emergent (BOS). It could be a question for managers to ponder in forming strategy. Arguably those in mature industries with strong market presence could and should identify with both aspects of ROS, BOS, however those just entering the marketplace unless squarely in the bos, may struggle with the principles in ROS. I believe that the ROS/BOS once you begin on the path of understanding your market can only help define your strategy which inevitably will sit in one of the four, classical, evolutionary, processualist or systemic which pretty much cover all strategies.
