Data are raw facts. Information is facts with context and perspective. Knowledge is information with guidance for action. Wisdom is understanding which knowledge to use for what purpose. B - Management.
Management is part of another hierarchy that includes supervision, management and leadership.
Supervision is dealing with individual tasks and people. And it works at the operational level of an organization or sub-unit. Management is dealing with groups and priorities at the tactical level. Leadership is dealing with purpose and change at the strategic level. A good working definition of knowledge management must be true to both concepts.
