In an agile culture, the people feel comfortable and empowered when there are many degrees of freedom available for them to define and work problems. This is the classic craftsman environment, where each person is expected and trusted to do whatever work is necessary to the success of the project. This includes looking for common or unnoticed tasks and completing them
In a plan-driven culture, the people feel comfortable and empowered when there are clear policies and procedures that define their role in the enterprise. This is more of a production-line environment where each person's tasks are well-defined. The expectation is that they will accomplish the tasks to the specification so that their work products will easily integrate into others' work products with limited knowledge of what others are actually doing.
