The COOEC assessment team employed a thorough, multi-faceted evaluation methodology designed to provide a complete picture of Dalian Crest's operational excellence:
The assessment commenced with a detailed examination of documentation provided by Dalian Crest, including project cooperation lists, cost-saving data, core patent certificates for equipment, and service capability statements. The team meticulously verified the authenticity, completeness, and accuracy of all submitted materials, paying particular attention to the feasibility of proposed solutions and the detailed calculation basis and validation evidence supporting cost-saving claims. This initial review established a foundational understanding of the company's history, cooperative track record, and technical service capabilities.
The assessment team conducted physical inspections of Dalian Crest's manufacturing workshops, R&D departments, and after-sales service facilities. During these visits, they evaluated production processes, quality control measures, and the practical application of equipment operation and maintenance manuals. The team also inspected the facilities and operational status of the after-sales service department.
Using a sampling inspection methodology, the team randomly selected equipment currently in production as well as completed finished products to verify compliance with quality standards. Additionally, they observed after-sales service personnel executing their operational procedures to ensure adherence to the revised "After-Sales Service Basic Process and Management System."
Face-to-face interviews were conducted with Dalian Crest's technical R&D personnel, production managers, and after-sales service staff. Using a structured interview framework covering technical R&D, production management, and after-sales service, the assessment team gained valuable insights into the company's internal management practices and operational culture. These exchanges allowed the team to evaluate employee professionalism, technical competence, and service orientation—critical factors in ensuring consistent product quality and reliable service delivery.
Following the document review, on-site inspections, and personnel interviews, the assessment team synthesized all findings through a combination of quantitative and qualitative analysis. The team systematically organized and analyzed the data and information collected throughout the assessment process, benchmarking Dalian Crest's performance against the established evaluation criteria and assessment objectives. The resulting assessment report provides a comprehensive evaluation of Dalian Crest's service capabilities and overall fitness as a strategic supplier.
