A process is a series of stages in time where the last stage is the product, result or goal.

Processes may be planned or unplanned.

A process planned by humans has a purpose. It is a course of action, or a procedure, to achieve a result, or an end-product. The sequence from start to finish is the plan. A plan may be written, or programmed, or just held in the mind. Examples include building a house, fighting a battle. sowing crops; organising a wedding.
