Final answer:
The essential components of System Analysis and Design (SAD) are methodology, project management, elaboration, and construction. A detailed design includes market analysis, shapes and dimensions of components, and consideration of criteria and constraints.
Step-by-step explanation:
Essential Ingredients of System Analysis and Design (SAD)
The question inquires about the four essential components of System Analysis and Design (SAD). These include a methodology, which is a systematic process of designing and analyzing systems; project management, which involves planning, executing, and controlling a project; elaboration, during which the project specifications are further refined and expanded; and construction, the actual building or coding of the system.
When we talk about the development of a detailed design, it is essential to understand it involves more than just the initial concept. The detailed design phase requires a comprehensive market analysis and defines the shapes and dimensions of all physical components. During this phase, criteria and constraints are considered, materials and fabrication processes are selected, and all components are identified and sufficiently detailed for prototyping.
The first step in the design process usually involves defining the problem, followed by exploring possibilities, generating ideas, and then selecting a design to develop.
