The Reliability and Risk Department considers quality to be one of the key drivers of the national economy. Quality management systems or integrated management systems (including maintenance management, occupational health and safety, etc.) are needed in some form for every organisation. The OSR's work is to assist with the normative implementation and improvement of these systems. OSR uses standard tools from quality and other disciplines to design and improve these systems and also applies its own developed management tools. The design or improvement of a management system may include process definition and optimization, characterization, identification and design of nonconformities, prevention procedures, design of documentation modifications, organizational structure changes, application of quality management tools, optimization of production and system quality costs, and internal audits. For example, in 2013, studies on the audit of the maintenance strategy and on the improvement of the quality management system in relation to maintenance management were prepared for Net4Gas, s.r.o.
