The product design specification (PDS) is a document created during the problem
definition activity very early in the design process. It details the requirements that must
be met in order for the product or process to be successful. The document lays the
groundwork for all engineering design activities and ensures that all relevant factors are
accounted for and all stakeholders are heard from. A typical PDS includes the following
information:
A. Product design & performance issues...
Expected product size and weight – customer requirement
