system transforms data into useful information. The end product of the data and process modeling is a logical model that will support business operations and hopefully meets user needs. Data and process modeling involves three main tools: data flow diagrams, a data dictionary, and process descriptions.

(pp. 65- 70), select a system in your work organization, or an organization that you are familiar with, and apply the causal loop diagram, including a reinforcing and balancing process. In a 1-2 page paper, briefly describe the purpose of the system, the components of the system, draw a casual loop diagram, and in plain language describe the diagram. Causal Loop Diagrams have four basic parts: * Point of Intersection (usually ellipses or circle) that contain values that can change * Lines with
