Leading High Performance Projects

The question arises: What are the characteristics of the prevailing paradigm that make it so difficult to manage and lead projects consistently to a successful conclusion? There are five key characteristics.

Not surprisingly, some people become extremely frustrated with the perfectionist approach because from an appearance perspective "nothing is getting done." Some project managers never go beyond the planning stage. They seek correctness in the plan without really knowing the criteria for determining what defines the perfection.
