Internal control, as defined by accounting and auditing, is a process for assuring of an organization's objectives in operational effectiveness and efficiency, reliable financial reporting, and compliance with laws, regulations and policies. A broad concept, internal control involves everything that controls risks to an organization.
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 Assessment, Information & Communication, Monitoring, and Control Activities).
The first step in control self-assessment is to document the organisation's control processes with the aim of identifying suitable ways of measuring or testing each control. The actual testing of the controls is performed by staff whose day-to-day role is within the area of the organisation that is being examined as they have the greatest ...
ISA 400 talks about the "walk through testing" or auditing in depth test. This standard was withdrawn in 2004, and has been replaced with the ISA 315, “Understanding the Entity and Its Environment and Assessing the Risks of Material Misstatement” and the ISA 330, “The Auditor’s Procedures in Response to Assessed Risks” [ citation needed ]
Systems theory is manifest in the work of practitioners in many disciplines, for example the works of physician Alexander Bogdanov, biologist Ludwig von Bertalanffy, linguist Béla H. Bánáthy, and sociologist Talcott Parsons; in the study of ecological systems by Howard T. Odum, Eugene Odum; in Fritjof Capra's study of organizational theory; in the study of management by Peter Senge; in ...
ORM is the oversight of operational risk, including the risk of loss resulting from inadequate or failed internal processes and systems; human factors; or external events. Unlike other type of risks (market risk, credit risk, etc.) operational risk had rarely been considered strategically significant by senior management. [1]
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.
Every control system must guarantee first the stability of the closed-loop behavior. For linear systems, this can be obtained by directly placing the poles. Nonlinear control systems use specific theories (normally based on Aleksandr Lyapunov's Theory) to ensure stability without regard to the inner dynamics of the system. The possibility to ...
