Question 1

SystemCollection of methods and procedures which are

formulated to perform a specific task or set of tasks

AnalysisDivision of the system into components to study how

those individual parts interact. There are three parts: survey and plan; study & analysis; definition

DesignDefining the architecture, components, interfaces and

data for a system to meet specific requirements

What is System Analysis & Design? – Broken Down

What is System Analysis & Design?

The stage where a development takes place effectively using hardware, software, data, processes, and liveware to accommodate the company's businesses motives. SAD can be optimized to maintain high-level requirements in the functional and non-functional found during analysis. The parts are further separated into smaller components which can be analyzed, designed, and developed individually and integrated together to form a single system. System Development Life Cycle (SDLC) and SAD goes hand-in-hand when it comes to providing a software solution. Conducted by a systems analyst

Question 2

Where in SDLC do you find SAD?

System Analysisprocess of collecting factual data, understand the processes involved, identifying problems and recommending feasible suggestions for improving the system functions.

System DesignBased on the user requirements and the detailed analysis of a new system, the new system must be designed. This is the phase of system designing. It is the most crucial phase in the development of a system.

Importance of SAD

Provide solutions for business problemsQuality analysisImprove the overall quality of the systemReduce chances of errorStandardize system analysis and design phasesEfficient data gathering and presentation

Importance of learning SAD as an undergraduate

University

Undergraduate

After joining the industry as a graduate, he or she should be able to have effective analyzing and designing skills gained by system analysis and design modules.
