• A. 30%
• B. 40%
• C. 50%
• D. 20%

Answer: (B)

The 40/30/30 rule is a framework used to analyze the contributions to scrap and waste in a manufacturing process, particularly as it relates to product design, production processes, and materials. According to this rule, it is understood that a significant portion of scrap and waste can be attributed to product design decisions. In this context, 40% of scrap and waste being attributed to product design highlights the critical role that initial design choices play in the efficiency and effectiveness of the manufacturing process. Poorly designed products can lead to increased waste through factors such as complicated shapes, excessive materials, or features that are difficult to produce. This emphasizes the importance of sustainable and efficient design practices to minimize waste and improve overall production efficiency. Understanding this rule helps supply chain professionals focus on the design phase as a key opportunity for improving sustainability and reducing costs associated with scrap and waste. By addressing design issues early on, companies can significantly lower their overall waste and enhance the sustainability of their operations.

When it comes to running a successful supply chain, a common framework to know is the 40/30/30 rule. Now, you might be wondering, what’s all the fuss about? Well, it’s a nifty little guideline, showing us that a whopping 40% of scrap and waste can be traced back to product design. Impressive, isn’t it? Let’s dive in and really understand what that means.
