Definition: Systems design is the process of defining elements of a system like modules, architecture, components and their interfaces and data for a system based on the specified requirements. It is the process of defining, developing and designing systems which satisfies the specific needs and requirements of a business or organization. Description: A systemic approach is required for a coherent and well-running system. Bottom-Up or Top-Down approach is required to take into account all related variables of the system. A designer uses the modelling languages to express the information and knowledge in a structure of system that is defined by a consistent set of rules and definitions. The designs can be defined in graphical or textual modelling languages. Some of the examples of graphical modelling languages are a. Unified Modelling Language (UML): To describe software both structurally and behaviourally with graphical notation. b. Flowchart : A schematic or stepwise representation of an algorithm. c. Business Process Modelling Notation (BPMN): Used for Process Modelling language. d. Systems Modelling Language (SysML): Used for systems engineering. Design methods: 1) Architectural design: To describes the views, models, behaviour, and structure of the system. 2) Logical design: To represent the data flow, inputs and outputs of the system. Example: ER Diagrams (Entity Relationship Diagrams). 3) Physical design: Defined as a) How users add information to the system and how the system represents information back to the user. b) How the data is modelled and stored within the system. c) How data moves through the system, how data is validated, secured and/or transformed as it flows through and out of the system.

Difference Between system Analysis and DesignSystem analysis can be defined as a deep analysis of a part of the structure of a module that has been designed before. System design means to make any module or a part of the structure from scratch and build it completely without estimation. System analysis is the process that is done on the existing model or the newly created model. But in the case of system design module is made from the raw data and has to build to a new structure using his own new ideas and concept. System Analysis lets you work directly on a project instead of thinking a lot about it as the module is prepared. This ensures the perfect execution and estimation of the project. Once the project is executed, the person working on it has to give a trial to the client. Further, when there would be an issue, the executive has to sit and clarify all the issues and make the changes as per the client’s requirement. The system design role starts when he is assigned to a particular project. The executive’s work is to collect all raw data, the need of the customer, dimensional parameter (if it is mechanical), structure to be designed, boundary conditions. Once he is done with all inputs, he starts planning with his team and begins to frame the work structure. The basic steps are taken, and further works on the project as per the given parameters. When the work of the system designer ends, then the work of system analysis starts.
