**Abstract**

Quality management systems are crucial for controlling and administering public institutions, promoting a culture of continuous improvement and reducing costs. This research evaluated three critical aspects in the fight against corruption in public procurement: risk management, compliance, and the implementation of ISO 37001 standards. Factors such as collusion between officials and companies, repetitive contracts, solvency checks, supplier experience, and certification were considered. The study found that collusion, procurement requirements, and supplier experience formed a pattern of fraud and corruption in companies. Compliance planning, internal procurement guidelines, training, commission monitoring, and contract evaluation were effective, but areas like planning and contract evaluation needed improvement. Low scores in implementing ISO 37001 standards indicated recognition but incomplete adoption, highlighting the need for stronger anti-corruption policies, ethical codes, and corruption identification practices.
