With the increasing complexity of engineering projects, quality control in engineering consulting services has become a critical component of project management. The PDCA (Plan-Do-Check-Act) cycle-based quality control methodology effectively enhances both service quality and operational efficiency. By analyzing the four phases of the PDCA cycle and integrating it with practical engineering consulting workflows, this paper proposes a comprehensive service quality control framework. The methodology includes: establishing clear quality objectives during the planning phase; standardizing service procedures in the execution phase; conducting quality assessments in the inspection phase; and implementing improvement measures through feedback mechanisms in the action phase. Practical implementation demonstrates that applying the PDCA cycle drives continuous improvement, enhances client satisfaction, and reduces project risks.
