This master's thesis is focused on the system of internal controls which is, in some form or another, implemented in every organization. In the theoretical part, the internal controls are specified according to the worldwide accepted integrated COSO framework for internal controls. Furthermore, there is briefly characterized internal audit, its aims and relation to the system of internal controls. The practical part deals with internal controls implemented in a specific organization. There were analysed control mechanisms implemented into the basic enterprise's process, the Order to Cash process.

This thesis deals with the internal control concept according to the COSO Integrated Framework for Internal Controls. Internal control definition, objectives and components are reviewed and commented. The emphasis is put on the auditor's understanding the entity's internal control and his responsibility to identify and assess the risk of material misstatement in the financial statements.

The current legislation that regulates internal managing and controlling system in administrative bodies of the public governance lags behind in the implementation of international experiences and standards for excersing the internal audits. This fact causes many reactions in the general public and also in the professional society. Alarming news about corruption and wasteful use of the public sources are just the token of the problem. The goal of this thesis is to define and analyze the process of implementing the managing and controlling system and subsequently to create a plan for a successful implementation of the effective managing and controlling system in the public governance. In the theoretical part are characteristics and goals of the managing and controlling system, legislative framework and description of components for the managing and controlling system, that are based on international experiences and practice. In the analytical part is the analyze of the particular elements from the managing and controlling system and finally in the practical part is the proposal of implementation managing and controlling system and also the proposal of directive for the internal control, which is supposed to simplify the practical use in the public governance. There is a draft of the assessment of Internal Control System Effectiveness in the practical part of this thesis.

Abstract in English, Afrikaans and Sepedi / The auditing profession is facing criticism for audit firms being associated with clients with a poor ‘tone at the top’ despite auditors being required to assess a company’s ‘tone at the top’, both prior to and during an audit. A problem arises if, should auditors perform an inappropriate ‘tone at the top’ assessment, they may be associated with an unethical company. Moreover, such an inappropriate assessment may result in an incorrect risk of material misstatement assessment and, consequently, an inappropriate audit opinion on the financial statements of the company. A qualitative research approach and a multiple case study design were used to understand how auditors assess a company’s ‘tone at the top’. An audit partner from six JSE-accredited audit firms and senior inspectors from the IRBA were interviewed. It was found that the participating auditors assess a company’s ethical leadership, ethical culture, the governance role of the audit committee and compliance with laws and regulations when assessing a company’s ‘tone at the top’ while adhering to quality control principles. Despite the participants acknowledging both that ‘tone at the top’ assessments are conducted during the pre-engagement and planning of an audit and that the audit engagement partner is responsible for these assessments, there was a lack of evidence in the audit files supporting these assessments. The study findings may enable audit firms to include guidance in their audit methodologies on ‘tone at the top’ assessments and in documenting such assessments and may also assist the IRBA in providing guidance and training to auditors on ‘tone at the top’ assessments. / Die ouditprofessie staar kritiek in die oë as gevolg van die feit dat ouditfirmas geassosieer word met kliënte met 'n swak “karakter aan die hoof”, ten spyte daarvan dat van ouditeurs vereis word om 'n maatskappy se “karakter aan die hoof” voor en tydens 'n oudit te assesseer. Die probleem is dat indien ouditeurs 'n onvanpaste assessering van die “karakter aan die hoof” uitvoer, hulle met 'n onetiese maatskappy geassosieer kan word. Boonop kan so 'n onvanpaste assessering aanleiding gee tot 'n verkeerde assessering van die risiko van wesenlike wanvoorstelling en, gevolglik, 'n onvanpaste ouditmening oor die finansiële state van die maatskappy. 'n Kwalitatiewe navorsingsbenadering en 'n veelvoudige gevallestudie-ontwerp is gebruik om te verstaan hoe ouditeurs 'n maatskappy se “karakter aan die hoof” assesseer. Onderhoude is met ouditvennote van ses ouditfirmas wat deur die JSE geakkrediteer word en senior inspekteurs van die IRBA gevoer. Daar is bevind dat die deelnemende ouditeurs 'n maatskappy se etiese leierskap, etiese kultuur, die beheerrol van die ouditkomitee en voldoening aan wette en regulasies assesseer wanneer 'n maatskappy se “karakter aan die hoof” geassesseer word terwyl aan gehaltebeheerbeginsels voldoen word. Ten spyte daarvan dat die deelnemers erken dat assesserings van “karakter aan die hoof” uitgevoer word tydens die vooraanstelling en beplanning van ’n oudit en dat die ouditaanstellingsvennoot verantwoordelik is vir hierdie assesserings, is daar 'n gebrek aan bewyse in die ouditlêers wat hierdie assesserings steun. Die studie se bevindings kan ouditfirmas in staat stel om leiding in hulle ouditmetodologieë in te sluit vir assesserings van “karakter aan die hoof” en om sodanige assesserings te dokumenteer, en dit kan die IRBA ook help om leiding en opleiding aan ouditeurs te gee vir sulke assesserings. / Profešene ya go hlakiša e lebane le tshekatsheko ka lebaka la difeme tša tlhakišo tšeo di amanywago le badirelwa ba ‘boikgafo le boetapele bja taolo’ bja go fokola, le ge bahlakiši ba nyakega go lekola ‘boikgafo le boetapele bja taolo’ bja khamphani, bobedi pele ga le nakong ya tlhakišo.
