Task: You are the quality control manager for a company that manufactures wooden toys. Your company is launching a new line of wooden blocks. You need to determine the LQ for these blocks.
Consider the following factors:
Instructions:
**LQ for Wooden Blocks:**
1. **Splinters:** Maximum of 0 splinters per block. 2. **Edge Smoothness:** Edges must be smooth to the touch, with no sharp edges or burrs. 3. **Size Deviation:** Maximum size deviation of +/- 2mm from the specified dimensions. 4. **Lead Content:** Must meet all applicable safety standards for lead content in toys. 5. **Aesthetic Appearance:** Blocks should have a consistent finish, with minimal visible blemishes or imperfections. **Justification:** * This LQ addresses the **product specifications** by requiring high-quality wood, smooth edges, and specific size tolerances. * It also meets **customer expectations** for safety, durability, and aesthetic appeal. * The **industry standards** for lead content are strictly adhered to. * While rejecting blocks with defects increases costs, this LQ is designed to be **realistic and achievable** while still ensuring high-quality products. By setting clear and reasonable limits, we can minimize the number of rejected blocks while maintaining customer satisfaction and safety.
