2. Question 1

3. What is System Analysis & Design? – Broken Down
System
Collection of methods and procedures which are formulated to
perform a specific task or set of tasks
Analysis
Division of the system into components to study how those
individual parts interact. There are three parts: survey and plan;
study & analysis; definition
Design
Defining the architecture, components, interfaces and data for a
system to meet specific requirements

4. 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
Analysis
Design

5. Question 2

6. Where in SDLC do you find SAD?
System Analysis
process of collecting factual data, understand the processes involved,
identifying problems and recommending feasible suggestions for
improving the system functions.
System Design
Based 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.

9. Where in SDLC do you find SAD?

10. Question 3

11. Importance of SAD
Provide solutions for business problems
Quality analysis
Improve the overall quality of the system
Reduce chances of error
Standardize system analysis and design phases
Efficient data gathering and presentation

12. 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.
