Regardless of type (e.g., charitable, corporate, social, government, etc.) organizations all share a set of common traits.  These influence the way the organizations members behave.

Heirarchy

This always exists in some form.  The structure could be pyramidical (most common) or relatively flat with shared authority and accountabilities.

The details of organization vary depending on type but ultimately there are rankings of authority (leaders, managers) and various other member levels.

Overall the relationships and authorities associated with the organizations members are defined .  This may be crystal clear or vague, either way, whether strictly defined or loosley defined a structure will exist.

Culture

The organizations leaders and managers, those recognized to have greater power, together with the organizations stated goals and objectives set the tone for how the members behave.

The Individuals

The organizational culture is further influenced by the capabilities and personalities of the entire membership of the organization.

Group Behaviour

The combination of the influences of the heirarchy (leadership structure, cultural and individual members personal traits) dictates the basic overall personality of the group (i.e, the group behaviour)

This ultimately impacts the organizations effectiveness.

When the combinations of structure, culture and individuality gel effectively, typically the organization itself over achieves. A key point here is no one factor alone can influence success.

For example having  effective leadership or an open and vibrant culture or a group of individual super people alone does not necessarily make for greatness.

Real success lies in the balance and integrated combination of all the above factors playing off each other like an orchestra.

Typically great leaders, skilled resoures or a stellar environment alone will not succeed unless the balance exists that binds them  and enables them to work seemlessly in concert.
