Sample text

However, choosing a different material at this point has very little economic impact provided the material costs are comparable. Development/design: Getting into the design phase and then discovering the stiffness problem would be annoying, but the economic impact would only be slightly greater than if the discovery was made during feasibility. Design validation: Having the design process mostly complete and then discovering the stiffness problem would cause some significant redesign and material selection rework.

What will the warranty rate and cost be?  Will the part work in the field on a consistent basis?  Will the part work as well in a new market?  Will the part fail in a dangerous way? Cross-functional, entrepreneurial team:  Does the product function?  What are the basic failure mechanisms of the product? Cross-functional, price point-driven commodity:  Can the product be made cheaper and still perform as well or better?  What will the warranty rate and cost be?  What are the basic failure mechanisms of the product?

Two curves can then be used for the ranking of cost to find information vs. the cost of not knowing. The “sweet spot” is where the sum of the two curves is lowest. ) Since the only way to examine the value of a piece of information at a particular time is to examine the cost of NOT having the piece of information, let’s examine three scenarios: 45 Accelerated Testing and Validation 1) A key physical property is wrong. 2) A primary failure mode of a product. 3) The mean time to failure. In each case, we will consider the potential economic impact of NOT knowing this information at different levels of development.
