There are lots of Strategy Models, some older, some younger. Competitive Strategy (Porter), Core Competencies Strategy, Disruptive Innovation Strategy (Christensen), Blue Ocean Strategy (Chan Kim & Mauborgne), etc. Strategy planning is still one of critical management activities in modern businesses today; also because Monitor is a strategy consulting firm co-founded by strategy master Porter, surely such discussion is not for gossip, but for brainstorming the strategy in strategy making, and learning more from failures with humility.
