What is meant by "Generic Specifications" in procurement perspective?

Generic Specifications are specifications that gives the required characteristics and performance requirements of the items specified without limiting the Contractor's options to a single manufacturer/ supplier or very narrow range of manufacturers/ suppliers.

I agree with the explanation given by Ahmed Hassaballah in general.

Generic Specifications is the main/wide specifications of a product or even a service, for the end user, they always prefer to use the full product specifications when ordering any item to ensure that the item will perfectly match his requirements and will be headache free, for us as procurement experts, we should always ask for the main/wide and generic specifications, so as to increase the competition and ensure that other similar or alternative products are quoted for by suppliers, at the end, user has to technically evaluate and confirm if the similar or alternative item is accepted or not with justifications.
