Explanation
Level of abstraction describes the breadth and depth of the information being provided. Representations of information may range from highly conceptual or summarized to very detailed. In determining how much detail each stakeholder may require as the initiative evolves, consideration is given to the needs of the stakeholders, the complexity of what is being explained, and the importance of the change. Rather than present the same information to all stakeholders, business analysts should present information with appropriate breadth and level of detail based on each stakeholder's role. Business analysis information regarding a topic of significant importance or high level of risk is frequently represented in greater detail.

Explanation
A state model describes:
*a set of possible states for an entity,
*the sequence of states that the entity can be in,
*how an entity changes from one state to another,
*the events and conditions that cause the entity to change states, and
*the actions that can or must be performed by the entity in each state as it moves through its life cycle.
While a process model can show all of the entities that are used in or affected by that process, a state model shows a complementary view: what happens to one entity across all the processes that affect it or use it.
