Specify what an acceptable manufacturing quality and/or Cost and/or carbon footprint is for the product.
The Product Industrialization expectations are manufacturing quality, building time, cost and carbon footprint. Manufacturing quality or the infant mortality part of the bathtub is caused by the manufacturing process. The other quality areas constant failure mode and wear out are influenced by the design and usage of the product.
Constant Failure Defect Rate
The Constant failure rate is mostly a measure for the expected failure mode of a part. Expectations are mostly set in a percentage of the number of parts which are allowed to fail per year. An example could be that the expectations for the fist 5 years a failure mode of 0.1%/year is set. However the first year is the sum of the infant mortality rate (manufacturing quality) + Constant failure rate. For all type of products as electronics, mechanics, mechatronics, optics, gas and fluids, .. the rules differ. An example of a outcome could be a manufacturing quality (infant mortality rate) of 0.05% or 500DPMO (ppm).
Wear Out Defect Rate
The wear out period is when the commercial or designed life stops and more and more failures manifest itself. This period is called the wear out phase and the product will not functioning at all any more.
This means that there must be an agreement on life expectation, failure rate acceptance during normal life and most important the acceptable number of failures during the first year of use.
Product Cost
The Product cost setting is mostly reflected by what a product is worth for the customer. This must be translated to the manufacturing cost.
Building Time
Building time is the time it need to build the prouct and is nothing more than the sum of all processes together. A more detailed view is the lead time which is shorter and represent the longest path in time to make the product. All not contributing parallel paths are neglected. Lead time is set for what is required/acceptable to manufacture the product.
Carbon footprint
Carbon footprint is the measure of how much greenhouse gases, like carbon dioxide and methane, released into the atmosphere by the product manufacturing. Carbon footprint is mostly set based on previous products.
