1. System Analysis & Design (SAD)

Definition:

System Analysis and Design is a structured approach to building and improving systems — primarily in software engineering or information systems.

System Analysis:

Studies current processes.
Identifies problems and inefficiencies.
Defines functional requirements.

System Design:

Specifies how the system will meet the requirements.
Includes architecture, data flow, UI, and technology stack.

2. Business Analysis with Statistical Analysis

Business Analysis:

Focuses on identifying business needs and solutions.
May involve creating reports, process maps, and system requirement specifications.

Statistical Analysis in Business:

Uses data (quantitative) to draw insights.
Common tools: Mean, Median, Standard Deviation, Regression, Forecasting.

Example Use Case:

A business analyst studying customer churn uses statistical analysis to identify patterns like age group, purchase behavior, or region — which feeds into system design to improve user experience.

3. Difference Between Physical System and Abstract System

Feature	Physical System	Abstract System
Definition	A tangible, real-world system	A conceptual or logical system
Nature	Concrete – made of people, hardware, etc.	Non-physical – models, theories, algorithms
Example	Computer, Human Resource Department, ATM	Software algorithm, data model, flowchart
Interaction	Can be seen, touched, and interacted with	Only mentally understood or digitally represented
Used In	Manufacturing, IT Infrastructure	Planning, system modeling, simulations

Examples:

Physical System:
- A car engine
- Hospital equipment
- Server farm
Abstract System:
- A database schema
- A business process model (BPMN)
- A financial forecast model

Mnemonic Trick to Remember:

“Physical is Touchable, Abstract is Thinkable.”
