William P. Leonard defines it: “Management Auditing is a comprehensive and constructive examination of an organizational structure of a company, institution, or branch of a Government, or of any component thereof, such as a division or department and its plans and objectives, its means of operations and its use of human and physical facilities”.
Taylor and Perry define it: “Management Auditing is a method of evaluating the efficiency of management at all levels throughout the organization, or, more specifically, it comprises the investigation of a business by an independent body from the highest executive level downwards, in order to ascertain whether sound management prevails throughout, and to report as to its efficiency or otherwise, with recommendations to ensure its effectiveness where such is not the case”.
