Events are a product of the Creative Process and the potential field is characterized according to quality of attention, clarity of visualized outcome and extent of intention to make it so. The lifecycle model for an event begins with the inclination to do something. The actual decision to act may never come and the possible way to act may take many forms. Each possible way to act that emerges into the creative process is thought to produce a potential field. How far into the process the event progresses determines the influence of the potential field.
