PDS Vs. Product Specification
The PDS is a specification of what is required but not the specification of the product itself. Describing the actual product is done in the technical specification, once the product has been designed. The difference is important since describing the product itself at the stage of creating a PDS, effectively constrains the range of alternatives that are considered during the design process.
The distinction can be seen as the difference between "What does the product do?" and "How will the product do it?"

Famous quotes containing the word product:
“[The political mind] is a strange mixture of vanity and timidity, of an obsequious attitude at one time and a delusion of grandeur at another time. The political mind is the product of men in public life who have been twice spoiled. They have been spoiled with praise and they have been spoiled with abuse.”
—Calvin Coolidge (1872–1933)
