Task: Imagine you are a quality inspector at a company that manufactures bicycles. You are inspecting a new batch of bicycles before they are shipped to customers.
Scenario: You notice that several bicycles have a loose handlebar stem, which could potentially cause safety issues.
Instructions:
1. **Defect:** Loose handlebar stem.
2. **Document:** You would document the defect in an inspection report, noting the specific bicycles affected, the type of defect, and the severity (e.g., minor, major). You might also include photos or sketches to illustrate the problem.
3. **Action:** You would recommend that the handlebars on the affected bicycles be tightened and checked for proper torque. You might also suggest a temporary hold on shipping the batch until the problem is resolved.
4. **Prevention:** To prevent this issue in the future, you could suggest a review of the assembly process for the handlebars, ensure that the correct tools are being used, and implement a double-check system for the handlebars before the bicycles are packaged.
