Let's analyze the graph and answer the question step by step: --- ### **Step 1: Understand the Axes** - **Y-axis:** Percentage of product cost committed (and incurred). - **X-axis:** Time (during the design of a product). --- ### **Step 2: Interpret the Two Curves** - **Cost Committed:** Rises rapidly early in the process, reaching almost 80% during the specification and conceptual design phases. - **Cost Incurred:** Increases slowly at first and only rises rapidly later in the process. --- ### **Step 3: Identify the Phases** - **Specification Development and Conceptual Design:** Most of the cost commitment happens here, even though actual spending (incurred cost) is low. - **Product Design:** Cost incurred starts to rise, but most cost commitment has already occurred. --- ### **Step 4: Draw the Key Conclusion** - **Most of the product cost is committed early in the design process (before much money is actually spent).** - **Decisions made early (in specification and conceptual design) have the greatest impact on final product cost.** - **Once in the later stages (product design and beyond), there's little opportunity to affect the overall product cost, even though this is when most money is actually spent.** --- ### **Step 5: Relate to the Effect of Design Process on Product Cost** - **The design process has a large influence on product cost.** - **To control or reduce product cost, focus on decisions made early in the design process.** - **Changes made later will have limited impact on total cost since most of the cost has already been committed.** --- ### **Final Answer (Conclusion)** > The conclusion from this graph is that the majority of a product's cost is committed very early in the design process, during specification and conceptual design. Therefore, decisions made during these early phases have the greatest impact on the total product cost. Efforts to control or reduce costs should be focused at the beginning of the design process, since changes made later will have minimal effect on the overall cost. --- Let me know if you want this in a different format or need more detail!
