An entity-level control is a control that helps to ensure that management directives pertaining to the entire entity are carried out. These controls are the second level [ clarification needed ] to understanding the risks of an organization.
Risks and controls may be entity-level or assertion-level under the PCAOB guidance. Entity-level controls are identified to address entity-level risks. However, a combination of entity-level and assertion-level controls are typically identified to address assertion-level risks. The PCAOB set forth a three-level hierarchy for considering the ...
There are two primary levels at which objectives (and also controls) are defined: entity-level and assertion level. An example of an entity-level control objective is: "Employees are aware of the Company's Code of Conduct." The COSO 1992–1994 Framework defines each of the five components of internal control (i.e., Control Environment, Risk ...
Control may be grouped according to three general classifications: [3] the nature of the information flow designed into the system (open- or closed-loop control) the kind of components included in the design (man or machine control systems) the relationship of control to the decision process (organizational or operational control).
These control criteria are to be used by the practitioner/examiner (Certified Public Accountant, CPA) in attestation or consulting engagements to evaluate and report on controls of information systems offered as a service. The engagements can be done on an entity wide, subsidiary, division, operating unit, product line or functional area basis.
The meta-data model of the control sub-process is based on a UML class diagram. Figure 2.1.2 shows the metamodel of the control sub-process. Figure 2.1.2: Meta-process model control sub-process The CONTROL rectangle with a white shadow is an open complex concept. This means that the Control rectangle consists of a collection of (sub) concepts.
This model influenced the ISA-95 (International Society of Automation) enterprise-control integration standards, [8] which expanded on the terms of the Purdue Reference Model and describes the interface between enterprise and control systems.

A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow — there are no decision rules and no loops.
