There's a world of difference between these two points of view. It's an excuse for inaction, a call to non-arms. In this sort of culture, you won't find people who proactively take steps to solve problems as they emerge. Plans don't accomplish anything, either. Theories of management don't much matter.
Endeavors succeed or fail because of the people involved.
Only by attracting the best people will you accomplish great deeds. In a brain-based economy, your best assets are people. We've heard this expression so often that it's become trite. Too often, people are assumed to be empty chess pieces to be moved around by grand viziers, which may explain why so many top managers immerse their calendar time in deal making, restructuring and the latest management fad. Organization charts are frozen, anachronistic photos in a workplace that ought to be as dynamic as the external environment around you.
