Working back from the end-of-life for a product, I propose these necessary deliverables for the product life cycle.

- Manage waste debt < 2024-02-29 Shirley Tseng pushed me to consider long term debt issues >

1. Output: plan for long-term management of non-reusable potentially hazardous disposed materials
   
   1. Examples: EV-Batteries, Radioactive materials

- Disposal: (*may be outside the scope of product developer*)

1. Output: is fundamental components that can be re-manufactured or disposed of in environmentally safe ways

- Re-purpose (*may be outside the scope of product developer*)

1. Output:
   1. production ready design information
   2. service information
   3. manufacturing information
   4. operating information
   5. retirement information (especially when retirement is mandated)
