Abstract

Due to the expansion of economic units with the emergence of multiple departments and branches, the expansion in the size of establishments, the complexity of administrative, financial and organizational activities, and consequently the difficulty of controlling and personal supervision of these activities, the role of internal control comes to overcome these difficulties and not the lesson in developing a sound system of internal control for any establishment, but the lesson in implementing this system accurately The consequences of not a sound system of internal control in the facility are the same as the consequences of having a system of internal control in the facility, but it is not applied. This research aims to develop a model for examining and evaluating the effectiveness and efficiency of the application of internal control procedures in economic units according to the structures of modern systems, including the (COSO) framework And to identify the strengths and weaknesses in it, and this model can be used by auditors and senior management to facilitate the process of evaluating the existing internal control system The research was built on the basic hypothesis (that the existence of a model for the checklist and evaluation of the application of the procedures of the internal control system according to the updated COSO framework would increase the effectiveness of the role of internal control in the economic unit in addition to identifying the strengths and weaknesses of the existing internal control system).The research came out with several conclusions, the most important of which are:1- There is a significant impact of applying the procedures of the internal control system according to the framework of the COSO Committee on the financial performance, which is the main nerve for the work of the profit-oriented economic units, of which the banks are the research sample, which would increase the effectiveness of the internal control.2- Setting performance levels by itself is not sufficient to achieve the existing oversight unless it is accompanied by performance monitoring to ensure compliance with these levels and follow the established procedures.3- The control environment is the basis upon which the rest of the internal control components are built.4- Weak commitment of most banks in the research sample to develop effective training policies to prepare competent employees to complete tasks in the least time and lowest cost.5- Lack of insurance for many people who have financial custody.The most important recommendations were:1- Applying an internal control structure in accordance with modern global frameworks, such as the framework of the Committee to Support Organizations (COSO) because of its link and impact on the financial performance of banks.2- The necessity of having a form for examining and evaluating the application of the procedures of the internal control system according to the framework of the COSO Committee.3- The need to commit to setting effective training policies to prepare competent employees to accomplish tasks in the least time and at the lowest cost.4-Insurance for all employees who have financial custody.
