Provide a model for identifying factors affecting audit quality Using Delphi method and fuzzy logic

Identification the factors affecting audit quality has always been one of the study challenges of audit researchers and often the internal factors affecting audit quality have been studied, but so far a model for identifying and balancing internal and external factors affecting audit quality using Delphi method and fuzzy technique have not been performed. Internal factors include inputs, processes, and outputs. External factors also include economic, cultural, and regulatory components that affect audit quality. In this study, 66 factors affecting the quality of auditing were counted based on the Delphi method. During different stages, 13 factors were excluded from these factors, which according to professional experts were less effective, and finally 53 factors, as the main factors were identified. In this study, based on the determined fuzzy number, 10 factors that had more weight in terms of affecting the audit quality were identified. According to the findings of this study, two factors, "scientific and technical competence of auditors" and "level of government support for the auditing profession" have had the greatest impact on the quality of auditing. Other factors are "independence and impartiality, expertise of the head of the audit team in the client industry, legal risk, emotional intelligence, level of economic transparency in society, culture of accountability and ranking of auditing firms by regulatory bodies". They affect the quality of the audit.
