Requirements

  • System Requirements in System Analysis and Design (SAD) define what a system should do and how it should perform. They are typically divided into two main categories: Functional Requirements and Non-Functional Requirements.
  • 1. Functional Requirements These specify what the system should do or the functions it must perform. They describe the interactions between the system and its users (or other systems) to accomplish specific tasks. Functional requirements are derived from the system's business needs and goals. Examples of Functional Requirements: User Authentication: The system must allow users to log in using a username and password. Order Processing: The system must process customer orders and update the inventory. Reporting: The system must generate sales reports in PDF and Excel formats. Notifications: The system must send email notifications when an order is shipped. Data Management: The system must allow users to create, read, update, and delete records in the database.
  • Common Tools to Define Functional Requirements:
  • Use Cases: Describes interactions between users and the system. User Stories: Short descriptions of system functions from the user's perspective. Process Flow Diagrams: Visual representation of how data or

Frequently asked question

System Analysis and Design (SAD) is the process of understanding, analyzing, and designing systems (software or hardware) to meet specific business or organizational requirements. It involves breaking down complex systems into manageable parts, defining system requirements, and designing solutions.

The main stages of SAD follow the System Development Life Cycle (SDLC): Planning: Defining objectives, scope, and budget. Analysis: Gathering and analyzing requirements. Design: Creating system architecture and design (data flow, interface, etc.). Implementation: Building, testing, and deploying the system. Maintenance: Ongoing support and updating of the system.

A System Analyst serves as a bridge between business stakeholders and IT teams. They gather and analyze business requirements, assess existing systems, design new systems or improve existing ones, and ensure the final product meets both user and business needs

Efficiency: It ensures that systems meet user needs efficiently. Cost-effectiveness: Proper planning and design reduce risks and save time and money in the long run. Scalability: SAD helps in designing systems that can grow and adapt to future needs. Risk reduction: By understanding system requirements early on, potential issues can be identified and addressed.
