This academic paper deals with the management system of JGArchitects, an architectural practice in New York - a city well known for its broad architectural offer. Titled "Improvement of JGArchitects' Management System [JMS] by standardizing and optimizing Processes", it is written in the field of quality management/ quality assurance. The focus of the analysis lies on identifying opportunities for improvement and on concepts to advance the system. The elaboration brings JGArchitects quality system into focus to increase both process stability and product quality. Three main aspects were discovered which needed to be improved to increase JMS efficiency: 1. Process control was restricted by partly not suitable measurement methods 2. The amount of change orders caused by architectural errors bear the opportunity for further reduction 3. JMS documentation process missed evaluation and standardized procedures.
