2. Question 1

3. 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 What is System Analysis & Design? – Broken Down

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.

7. Where in SDLC do you find SAD? – Actual Stages System Analysis Requirement Analysis Requirement Specification System Design Logical System Specification Logical Designing Physical Designing Analysis Design

8. Stages of System Development Life Cycle Strategic study Business study Feasibility study Requirement analysis Requirement specification Logical system specification Logical design Physical design Coding Testing Implementation Maintenance Phase out

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.
