One of the systems engineer s most important contributions is the abflity to identify and meet the needs of the customer and do it within the project budget. Based on the customer s initial concepts and any subsequent equipment utilization research conducted by the systems engineer, the desired capabilities are identified as precisely as possible. Design parameters and objectives are defined and reviewed. Functional efficiency is maximized to allow operation by a minimum number of personnel. Future needs are also investigated at this time. Future technical systems expansion is considered. 

The process of defining the items or elements below system level involves substantial engineering effort. This design activity is accompanied by analysis, trade studies, modeling and simulation, as well as continuous developmental testing to achieve an optimum definition of the major elements that make up the system, with associated functionality and performance requirements. This activity results in two major systems engineering products the final version of the system performance specification and draft versions of the performance specifications, which describe the items below system level (item performance specifications). These documents, in turn, define the system functional baseline and the draft allocated baseline. As this activity is completed, the system has passed from the level of a concept to a well-defined system design and, as such, it is appropriate to conduct another in the series of technical reviews.

User requirement specifications cover more aspects than only the GMP requirement, because the URS is not written only for the validation procedure in fact, a URS is a very important project document covering technical as well as economic requirements of the technical system. Pharmaceutical manufacturing departments not only check the GMP aspects of a system additionally, following good engineering practice they will review the technical and economic aspects of a technical system. Obviously, the more experience a company gains, the more comprehensive a URS become. Past experiences such as project faults, inefficient technical systems, and bad commissioning can be included in a URS.
