Definition of the term („What is an user requirement specification?“) 

A URS or User Re­qui­re­ment Spe­ci­fi­ca­ti­on con­ta­ins a com­pre­hen­si­ve de­scrip­ti­on of the cus­to­mer re­qui­re­ments with re­fe­rence to the pro­ducts and ser­vices of a con­trac­tor. This also in­cludes the eco­no­mic, tech­ni­cal and or­ga­niza­tio­nal ex­pec­ta­ti­ons for a de­vice, ap­pli­ance or a product/service. In the soft­ware sec­tor, for ex­am­p­le, it is the re­sult of a re­qui­re­ment ana­ly­sis and this part of the re­qui­re­ment ma­nage­ment. Ul­ti­m­ate­ly, the URS also de­fi­nes ob­jec­ti­ves and purposes.

Wi­thin ten­ders, the con­trac­ting en­ti­ty may send the URS to se­ve­ral po­ten­ti­al con­trac­tors and then compa­re them with the func­tion­al spe­ci­fi­ca­ti­ons pro­vi­ded in­di­ca­ting the dif­fe­rent so­lu­ti­ons ad­opted by the contractors.
