What is organizational architecture? 
You wouldn't think of building a home or complex structure without an architect's blueprint - the plan.  Business organizations need a plan too.  Organizational architecture is the structural blueprint for your business and comprises four primary pillars: culture, strategy, structure, leadership.

Culture describes the personality of an organization.  Value systems, beliefs and behaviors are perhaps the strongest components. Add diverse personalities, different motivations and you have a unique corporate culture.
Every organization has one.

Strategy is really the art of creating and deploying a system of activities that moves all company resources toward a goal.  It is the roadmap to success.  It is vision, mission and values.

Structure organizational structure (sometimes compared to the human brain) is the most complex network of all.  This network of groups, systems, roles, relationships, processes and communication all work together to perform the work.

Leadership is creating and nurturing an environment where all organizational components (culture, strategy, and structure) work together. Leadership is anticipating change and facilitating change through trust, collaboration, knowledge and empowerment.
