Systems design 41774 222606512 2008-06-30T06:18:23Z Danhiel 4937959 /* External links */ changed to link to definitions in English to match the current page '''Systems design''' is the process or art of defining the architecture, components, modules, interfaces, and [[data]] for a [[system]] to satisfy specified [[requirement]]s. One could see it as the application of [[systems theory]] to [[product development]]. There is some overlap and synergy with the disciplines of [[systems analysis]], [[systems architecture]] and [[systems engineering]]. == Overview == If the broader topic of [[product development]] "blends the perspective of marketing, design, and manufacturing into a single approach to product development<ref>{{cite book | last = Ulrich & Eppinger | title = Product Design & Development | publisher = Irwin McGraw-Hill | year = 2000 | id = ISBN 0-07-229647-X}}</ref>, then design is the act of taking the marketing information and creating the design of the product to be manufactured. Systems design is therefore the process of defining and developing a [[system]]s to satisfy specified [[requirement]]s of the market or customer. Until the 1990s systems design had a crucial and respected role in the [[data processing]] industry. In the 1990s [[standardization]] of hardware and software resulted in the ability to build [[Modularity (programming)|modular]] systems. The increasing importance of software running on generic platforms has enhanced the discipline of [[software engineering]]. [[Object-oriented analysis and design]] methods are becoming the most widely used methods for computer system design. The [[Unified Modeling Language|UML]] has become the standard language used in [[Object-oriented analysis and design]]. It is widely used for modeling software systems and is increasingly used for designing non-software systems and organizations. == Systems design: Topics == * [[Requirements analysis]] - analyzes the needs of the end users or customers * [[Benchmarking]] — is an effort to evaluate how current systems are used * [[Architectural design]] - creates a [[blueprint]] for the design with the necessary specifications for the hardware, software, people and data resources. In many cases, multiple architectures are evaluated before one is selected. * [[Design]] — designers will produce one or more 'models' of what they see a system eventually looking like, with ideas from the analysis section either used or discarded. A document will be produced with a description of the system, but nothing is specific — they might say 'touchscreen' or 'GUI operating system', but not mention any specific brands; * [[Computer programming]] and [[debugging]] in the software world, or detailed design in the consumer, enterprise or commercial world - specifies the final system components. * [[System testing]] - evaluates the system's actual functionality in relation to expected or intended functionality, including all integration aspects. == See also == * [[Electronic design automation]] * [[Electronic system level]] * [[Embedded system]] * [[Graphical system design]] * [[Operating Systems Design and Implementation]] * [[Structured Systems Analysis and Design Method]] * [[Systems Development Life Cycle]] * [[Systems thinking]] == References == <references/> == Further reading == * Maier, Mark W., and Rechtin, Eberhardt, The Art of Systems Architecting, Second Edition, CRC Press, Boca Raton, 2000 * J.H.
