Quality Inspector/Quality Assurance

• Conduct Risk assessment with physical jobs.
• Identify duplicates, by doing a comparison on both SAP MM and SAP MDM.
• Measuring quality of equipment.
• Examine the quality of the equipment for defects. Inspect if the correct equipment was delivered, as well as deviations from drawings and other discrepancies.
• Ensure the correct delivered equipment is documented under the correct Kumba identification number.
• Inspect reconditioned equipment before it is send away for repairs as well as on returning from the RECO process.
• Spot overpricing in many of the equipment received, in which case we communicate with the buyer and the contracts department to investigate the reason, or to explore new companies.
• If tests are performed I manage inventory efficiency.
• Visit vendors(site inspection), especially in the case of RECO items to ensure they comply with mine standards, and to verify if the scope of their contract are met as precisely as possible.
• Intensive and detailed technical quality inspection enabled with integrated wireless bar-coding and scanning technology (scanner) linked with SAP Material Management which in turn is linked to SAP Master Data Management (SAP MDM).
• Leading small projects.
• As quality inspector I am the direct link between supply chain and end users ex: -mining -engineering, -production teams etc…
• I work on SAP MM daily and also have some SAP PM experience.
