Jurnal Materi Perancangan Produk 6 ( System Level Design)

hari ini kami membahas sedikit tentang System level design, berikut adalah materinya


Systems design is the process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements. One could see it as the application of systems theory to product development. There is some overlap with the disciplines of systems analysis, systems architecture and systems engineering.^[1][2] If the broader topic of product development "blends the perspective of marketing, design, and manufacturing into a single approach to product development,"^[3] 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 systems to satisfy specified requirements of the user. 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 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 systems design.^{[citation needed]} The UML has become the standard language in object-oriented analysis and design.^{[citation needed]} It is widely used for modeling software systems and is increasingly used for high designing non-software systems and organizations.^{[citation needed]}

[edit] Logical design

The logical design of a system pertains to an abstract representation of the data flows, inputs and outputs of the system. This is often conducted via modelling, using an over-abstract (and sometimes graphical) model of the actual system. In the context of systems design are included.

[edit] Physical design

The physical design relates to the actual input and output processes of the system. This is laid down in terms of how data is input into a system, how it is verified/authenticated, how it is processed, and how it is displayed as output.
Physical design, in this context, does not refer to the tangible physical design of an information system. To use an analogy, a personal computer's physical design involves input via a keyboard, processing within the CPU, and output via a monitor, printer, etc. It would not concern the actual layout of the tangible hardware, which for a PC would be a monitor, CPU, motherboard, hard drive, modems, video/graphics cards, USB slots, etc. it involve detail design of user and a product database structure processing and control processor .The H/S personal specification a develop for the proposed system .

[edit] Alternative design methodologies

[edit] Rapid application development (RAD)

Rapid application development (RAD) is a methodology in which a systems designer produces prototypes for an end-user. The end-user reviews the prototype, and offers feedback on its suitability. This process is repeated until the end-user is satisfied with the final system.

[edit] Joint application design (JAD)

Joint application design (JAD) is a methodology which evolved from RAD, in which a systems designer consults with a group consisting of the following parties:

• Executive sponsor
• Systems Designer
• Managers of the system

JAD involves a number of stages, in which the group collectively develops an agreed pattern for the design and implementation of the system.
