If you want to learn and discuss about competitive strategy, my friend Marco has started a very interesting blog on the subject. As an expert manager and consultant, Marco collects is thoughts and discuss books and articles about strategic management. Sometime we need to stop, exit from day by day activities and think out of the box to evaluate whether we are following a strategic path or just following short-term tactics.
