Risk odaklı iç denetim sürecinde operasyonel risklerin belirlenip ölçülmesine yönelik uygulamalı bir 3x5 risk matriksi ve risk analiz anket formu önerisi
(İstanbul Serbest Muhasebeci ve Mali Müşavirler Odası, 2018) Aksoy, Tamer; Aksoy, Tamer; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Son yıllarda gözlenen küreselleşme, hızlı değişim, teknoloji, rekabet vb sebebiyle işletme hedeflerine ulaşılmasının önemi artmıştır. Gelişmeler ve değişen koşullar iç denetim paradigmasını risk odaklı iç denetim yönünde değiştirmiştir. Hem risk odaklı yönetimde hem de risk odaklı iç denetim (ROİD) sürecinde yüksek riskli alanlara odaklanma artık hayati önemdedir. Bu doğrultuda, işletme risklerinin proaktif olarak önceden belirlenmesi, ölçülmesi ve önceliklendirilmesi risk yönetimi (RY) süreci bağlamında önemli hale gelmiştir. Çalışmada, öncelikle risk odaklı denetim temel özellikleriyle incelenmiştir. Ayrıca örnek bir çimento şirketinin finansal tablo hesaplarının muhasebeleştirilmesindeki operasyonel risklerin skorlanmasına yönelik 3x5 risk matrisi ve risk analiz anketi uygulanmıştır. Sonuçta, öncelikle karşılaşılan operasyonel riskler tanımlanıp risk envanteri oluşturulmuştur. Ayrıca, risk skorlaması neticesinde operasyonel risklerin çok büyük kısmının düşük risk, çok cüz’i kısmının da rutin süreç iç kontrolleri ile giderilebilecek orta risk seviyesinde olduğu, yüksek riskli kategoride ise herhangi bir riskinin bulunmadığı anlaşılmıştır. Ayrıca orta risk seviyesindeki detay alt risklerin kendi ana hesap grupları da düşük risk kategorisinde çıkmıştır. Dolayısıyla şirketin ilgili süreçlerindeki iç kontrollerin ve iç kontrol sisteminin yeterli ve etkin olduğu, çalışanların iç kontrol ve risk kültürüne yönelik farkındalığının bulunduğu sonucuna varılmıştır.
The effectiveness of the internal control system in preventing operational risks to income statement issuance: A practical risk-based internal audit perspective
(EBES Publications, 2021) Aksoy, Tamer; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
In recent years, corporate risk management (CRM) has gained great importance in companies with the effect of various factors such as technological development, globalization, rapid change, increase in competition, information technologies, deregulation, global scandals, supranational companies, corporate governance. The understanding of internal audit has evolved from classical auditing to risk-based internal auditing(RBIA). Focusing on high-risk areas has come to the fore in RBIA in terms of ensuring efficiency, productivity and sustainability. Proactive pre-determination, measurement and prioritization of business risks, especially operational risks(ORs), which constitute the most difficult risk group to detect, identify, reveal, quantify, measure and evaluate, have come to life in the CRM process. In this study, the effectiveness of the internal control system(ICS) in preventing ORs related to income statement issuance is examined in the context of a company application example from RBIA optics. In the study, a tomato paste&frozen canned food company listed on the Stock Exchange (Borsa Istanbul-BIST) was selected from the leading member companies of the TGDF and SALKONDER. Methodologically, a survey method based on a risk assessment questionnaire on a 5x5 Likert scale was used to collect data and create a risk inventory. The questionnaire was applied to the group consisting of officers, experts, chiefs, assistant managers, managers, relevant senior managers and internal auditors who are involved in preparation and follow-up of the income statement in the financial affairs/internal audit departments. An Excel macro program was used to calculate the coefficients in the risk analysis questionnaire/matrix in the context of the probability of the risk occurring and the possible impact of the risk. Considering the preferences and risk coefficients, the risk score for each defined OR&main account group was determined and prioritized and made visible in the low, medium, high risk categories both in the risk matrix/analysis questionnaire. After ORs were scored, they were prioritized by ranking them both within the relevant&main account group/headings. The study revealed that most of the direct ORs defined for income statement, except for two items, are in the low risk group. Additionally, the study showed that the risk score of the two items (compliance with IFRS&VUK-TPL, independent audit reporting) remaining in the medium risk group as an individual item is in the low risk category. Finally, considering the assessment of relevant stakeholders, the study showed possible ORs were largely eliminated within the control sequence in the processes and the existing ICS and were in a tolerable condition.
Banking in Türkiye: History, evaluation, and role in the financial system
(Springer Nature, 2023) Aksoy, Tamer; Aksoy, Tamer; Aksoy, Tamer; Güzel, Adnan; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
In Turkey, the banking industry produces the most significant and biggest share of the Turkish Finance System. Foreigners made a high number of banking transactions in Turkey during the early years of the Republic. The capital structure of the Turkish banking system held by foreigners has always been a source of debate, and as a result, attempts to promote national industry and banking have been prioritized throughout the Republican Era. The Central Bank was established in 1931, followed by several Turkish-owned banks, and it is still in operation today. Despite the effects of the 1929 Great Depression, World War II, changes in the world’s monetary system, the establishment of international financial and economic unions, oil shocks, and frequently encountered financial crises, the most notable development process of Turkish banking dates back to the Republican Era. During this period, banks were founded to give state assistance for any industry or to get financial facilities for major industrial groupings to carry out their activities. Following the 1980s, when globalization accelerated and financial deregulation occurred, the banking industry developed significantly and has become one of the most important industrial businesses supporting Turkey’s economic development. During this period, the country’s economic policies have been significantly altered, and a free market economy has been introduced. Following the financial crisis that hit Turkey in 2001, critical banking reforms were implemented. Such arrangements have bolstered the Turkish economy and financial system, as well as aided the progress of Turkey’s integration into global markets. Following a general overview of banking history in the world, this study makes specific references to developments in Turkey in light of modern banking history, with explanations on today’s process for a complicated, supranationalized, and technology-focused structure, the crisis experienced, and the reforms implemented.
A systematic analysis of internal control requirement in the light of scandals, standards and regulations and a coso based internal control list proposal for corporate businesses
(EBES Publications, 2020) Aksoy, Latif; Aksoy, Tamer; Aksoy, Tamer; Yönetim Bilimleri Fakültesi, İşletme Bölümü
The scandals in the past increased the importance of internal control (IC) and of the IC system (ICS) and created a global awareness. Many factors played a role in the formation of scandals. Issues such as the lack of ICS and not being operated effectively and their effectiveness not being subjected to control and supervision also played an important role. The issue of IC necessity and the effectiveness and oversight of ICS were been subject to a wide range of standards and regulations, including the Sarbanes-Oxley Act (SOX). The necessity of IC and effectiveness of ICS were tried to be guaranteed with standards/regulations. So, corporate and individual responsibilities for ICS and for its effectiveness have been significantly increased with standards/ regulations. Ensuring the effectiveness of the ICS is the guarantee of reliable information and accurate and reliable reporting. Besides, an effective ICS is important for some aspects(protecting assets and common interests of stakeholders/ achieving goals/ ensuring the profitability and efficiency of activities/ management and accounting control/ compliance with regulations, corporate management and ethical principles/ quality assurance/ CRM/ transparency/ accountability etc). In this regard, the main responsibility for the ICS and its monitoring was given to the board of directors of the company. The independent auditors were undertaken for the effectiveness of ICS to point out and give attestation in their reports. The effective ICS provides various benefits to the audit. As the effectiveness of the ICS increases, the audit risk and duration of audits decreases, the number of evidence the auditor needs to collect and the audit cost decreases. In our study, an internal checklist proposal is presented to be used to evaluate the existence and/or effectiveness of ICS. The internal checklist is compatible with COSO IC framework, the most comprehensive and most advanced model developed for businesses. It is evaluated that the COSO based IC list will provide benefit for the evaluation of effectiveness of ICS. IC list is hoped that it can be used by the board, audit committee, independent/internal auditor, advisory companies and researchers. Finally, using the proposed IC list can make it possible to determine the effectiveness of ICS and to draw attention upon the weaknesses/deficiencies and risks that need to be corrected and improved.

(Elsevier, 2023) Hacıoğlu, Ümit; Aksoy, Tamer; Hacıoğlu, Ümit; Aksoy, Tamer; Dinçer, Hasan; Yüksel, Serhat; Aksoy, Tamer; Hacıoğlu, Ümit; Mikhaylov, Alexey; Pinter, Gabor; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
The purpose of this study is to examine optimal solar module investments. Firstly, key determinants of the performance of solar energy investments are evaluated by DEMATEL method with the 2-tuple IVIF sets. Moreover, the cell material alternatives for solar module investments are also ranked. For this purpose, an evaluation has been made by 2-tuple IVIF TOPSIS. The contributions of the paper are performing a priority analysis to understand the most significant factors to increase solar energy projects and creating an original model by the integration of DEMATEL and TOPSIS with the 2- tuple IVIF sets. The findings denote that crystalline silicon is the optimal solar panel module to increase the performance of these projects. In the short term, government subsidies can provide cost advantages to solar energy investors. It is not a very continuous practice to try to increase these projects only with government supports. The costs of solar energy projects should be reduced to solve this problem permanently. Owing to new technological developments, high cost problem of solar energy investments can be handled more successfully.
Application of M-SWARA and TOPSIS methods in the evaluation of investment alternatives of microgeneration energy technologies
(MDPI AG, 2022) Hacıoğlu, Ümit; Aksoy, Tamer; Hacıoğlu, Ümit; Aksoy, Tamer; Dinçer, Hasan; Yüksel, Serhat; Aksoy, Tamer; Hacıoğlu, Ümit; Yönetim Bilimleri Fakültesi, İşletme Bölümü; Yönetim Bilimleri Fakültesi, İşletme Bölümü
Investments in microgeneration technologies help to boost the usage of clean energy while reducing pollution. However, selecting the appropriate investment remains the most critical phase in developing these technologies. This study aims to design a multi-criteria decision-making method (MCDM) to evaluate investment alternatives for microgeneration energy technologies. The proposed MCDM is based on a Multi Stepwise Weight Assessment Ratio Analysis (M-SWARA), to define the relative importance of the factors. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and q-Rung Orthopair Fuzzy Soft Sets (q-ROFSs) are used to rank investment alternatives. Calculations were also made with Intuitionistic Fuzzy Sets (IFSs) and Pythagorean Fuzzy Sets (PFSs). For analysis, five evaluation criteria were selected based on the literature: frequency of maintenance, ease of installation, environmental adaptation, transmission technologies, and efficiency of cost. Similarly, six alternatives for microgeneration technology investments were selected: ground source heat pumps, micro hydroelectric power, micro combined heat and power, micro bioelectrochemical fuel cell systems, small-scale wind turbines, and photovoltaic systems. The results showed that cost efficiency was the most significant factor in the effectiveness of microgeneration energy investments, and the photovoltaic system was the best alternative to increase microgeneration energy technology investment performance. Furthermore, the results were the same for the analyses made with IFSs and PFSs, demonstrating the reliability of the proposed method. Therefore, investors in microgeneration technologies should prioritize photovoltaic systems. This conclusion is supported by the fact that photovoltaic is a renewable energy source that has witnessed the most technological improvements and cost reductions over the last decade.
