Companies, teams and groups align most strongly behind a common, committed purpose.  Defining that purpose, and then articulating it in a way that can be easily understood, is an essential ingredient for success.  It's the foundation beneath the strategy, organisation, resources and systems of a business.   And profit alone is not a sufficiently motivating purpose.  

When a company has a clear purpose, a strong "Why?", then decision making and resource allocation become much more straightforward.  It helps support the question of "what are we trying to achieve?" or "what's the objective here?".  And those questions in turn help determine what you prioritise and where you focus your time and effort.

The stronger the purpose the easier it is for a group to achieve hyper-alignment, with everybody focused and aligned in the same direction with a common core objective.  And that's the key to success in any venture.
