System Design Specification definition

A system design is a product that is made up of a combination of devices and components. As described above the devices within a system are under the control of the designer and are designed specifically for the system. Components, on the other hand, are other devices and/or subsystems which are not made to the specification of the system designer. Usually these components are manufactured for a number of applications in various systems. Thus, the system design and the fabrication of the system are under the control of the system designer. The definition of a system infer complexity in design and operation. 

The P-diagram is a tool used to conceptualize the System Design Specification (SDS). The system spedlication establishes boundaries, describes the organization that is responsible for the requirements, and acts as a source definition of the essential requirements for the component. The system specification will also eventually link requirements to the design verification methods, which are tests that are designed to prove functionality.

In order to optimise individual structures in the lO-design the definition of parameter-loops and scanning routines is required. In combination with this, post-processing of BPM-runs to evaluate channel-specific mode amplitudes, system transmission etc. is necessary, as well, which is assisted by eommercial lO-design tools, naturally. This facilitates the generation of parametric models for any optical sub-system, cf. figures 11 and 12, which at the end is a prerequisite for an efficient system design. 

A pharmaceutical manufacturing system design requires significant level of innovation. The broadest definition of innovation is the act of introducing something new to a society or community, whether a product or process. This is often confused with invention, which focuses more on specific objects. Within pharmaceuticals innovation can therefore include new business structures within the company,... 

It is recognized that the URS may be superseded by the FDS as the definitive specification for system design. The URS, however, remains the technical and operations statement of user requirements and must be maintained under change control as an up-to-date document throughout the life of the system. The URS also remains the base document against which PQ is verified, and once the URS is approved a PQ test plan can be generated. 

The Functional Specification should, as far as possible, avoid detailed design and concentrate on defining the operation and user interaction with the computer system. This is generally more difficult than it sounds. In some instances it is not even applicable because the URS specifically requests particular equipment or a particular design to be used. Similarly for small projects, it is often more convenient to combine the Functional Specification and Design documents into what is often referred to as a Functional Design Specification, System Definition, or System Description. 

Following on from the URS, a system definition consisting of Functional Design Specification (FDS) needs to be collated. The URS does not necessarily specify the chosen MRP II system, and if this is the case, the FDS will need to introduce and overview the selected MRP II system. The FDS will define the URS business processes at a transaction level. Referenced documentation published by the supplier defining the standard MRP II software product and its functionahty should be retained and maintained with the current version of the MRP II software used. It is important to identify those functions of the standard MRP II system that are used and specifically document which functions are not being used. 

SRS uses metadata to define a class for a database entry object and uses rules for text-parsing methods, which are coupled with database entry attributes. For object definitions and recursive text-parsing rules, SRS uses its own scripting language called Icarus. For library specification and organization and for the representation of individual data fields within a system, SRS uses a Object Design and Definition (ODD) language.
