The purpose of all work that is carried out within or on behalf of an organisation should be to accomplish the mission of the organisation.

Generally, an organisation, profit or non-profit, will require many people to contribute to the work that must be done to accomplish the mission.

People are the most important resource of an organisation and, as such, a great deal of co-ordination is required to ensure this resource is used effectively.

One important step is to assign job roles and responsibilities to people.

The assignment of roles may occur as a result of:

(a) A person stepping forward to volunteer for a role i.e. receive no payment of money; or

(b) A person being recruited and employed on a paid basis to undertake a role.
