I developed QCTrack, a digital quality control system tailored for a lighting manufacturing company to log, manage, and analyze product non-conformance issues, whether identified internally or returned from the field. The platform streamlined issue tracking, accountability, and root cause analysis, significantly improving traceability and process improvement efforts.
-
Issue logging interface for relevant staff to report non-conformances:
- Attach images and provide detailed descriptions.
- Select from a predefined list of common fault categories for consistent classification and future analysis.
- Identify the responsible department (e.g., Technical, Mechanical Design, Production).
-
Automated email notifications sent to the assigned individuals within the responsible department, including fault details and images.
-
Root cause analysis workflow:
- Responsible parties provide cause investigation, preventative measures, and cost tracking (e.g., replacement components).
- Issues can be attributed to categories such as supplier error or production procedure fault.
- If supplier-related, their details are logged for follow-up.
-
Issue closure validation ensures that all required fields are completed before an issue can be marked resolved.
-
Auto-generated QC reports:
- Upon closure, a PDF report is automatically created and emailed to the original reporter.
- Includes all relevant data, including client information for traceability and customer communication.
-
Interactive analytics dashboard:
- Filter and visualize data to identify trends by product, fault type, or supplier.
- Interactive bar charts allow users to click on a product or category to view associated issues.
- Used actively in QC meetings and ISO audits to demonstrate issue resolution processes and trend tracking.
Built with a stack including Nuxt.js, Node.js, MySQL, and an integrated SMTP email service, QCTrack became a core part of the company's quality assurance and continuous improvement strategy.
