Gustavus Adolphus thought so. The great King and General used flexible military formations to create Sweden's great empire. (Sweden had an empire? Who knew?) Today, the US military prefers guided missiles, robots, and drones to heavy artillery. Flexibility results in a W many times simply because it adapts to changing circumstances, and there's nothing like a conflict for generating those. Moreover, people seem to fall into mental comfort zones that lead to big, expensive, heavy, cumbersome resources, sure-things, that run along on rails and have the capacity for decimating anything in their path. That's great, so long as the things you're targeting agree to step in front of you. Flexible enemies won't.
Square Enix, developers of Final Fantasy XIV, have gambled that most people don't really think of flexibility as power. In this video (thanks to Travis Ross for the link), they explain their new solution for a rather intractable problem: When you put millions of people in a game with levels, some of those people burn through the levels quickly, others more slowly. Real life is like that, too. Name an achievement area; no matter what it is, some people zoom right to the top, the rest of us plod along. It's because we all have different resources: Some have more time than others, some understand fighting with pikes and muskets better than others, some are taller, some have a brain well-adapted to grasping the intricacies of Lady Gaga's social circle while others of us do not.
Such inequalities in skill are inevitable; they are part of being human. Are inequalities in outcomes also therefore inevitable?
