Study Notes

Waterfall Project Management

Traditional linear approach structured in four phases: Initiation, Planning, Executing and Controlling, Closing.
Phases flow top-down, with each dependent on the completion of the previous one, minimizing changes post-initiation.
Ideal for projects with clearly defined requirements, such as construction, manufacturing, and research.
Less effective for projects with uncertain customer requirements.

Agile Project Management

Predominantly used in IT projects, developed in the 1990s specifically for the software industry.
Emphasizes flexibility and adaptability throughout the project lifecycle.
Utilizes user stories to define project requirements from an end-user perspective, focusing on user needs and outcomes.
Ensures alignment with business goals and enhances user satisfaction.

User Stories

Core component of Agile methodologies, simplifying project requirements through plain language descriptions.
Provides a practical way to convert user needs into actionable tasks.
Allows teams to prioritize features based on user importance and feedback.

Use Cases

Defines interactions between users and systems for achieving specific goals.
Outlines scenarios depicting how stakeholders interface with project deliverables.
Essential for setting clear expectations and guiding feature development throughout the lifecycle.

Requirements Analysis

Central focus is to determine elements needed for optimal system function, addressing data, software, hardware, job skills, and protocols required for an EIS (Enterprise Information System).

Systems Design

Translates functional and non-functional requirements into a structured system architecture and blueprint.
Involves defining system architecture, technology stack, data flow interaction, and user interface design.
Essential for preventing scope creep and ensuring focus on outlined project features and functionality.

Functional Requirements

Describe what the system must achieve, outlining specific behaviors, tasks, and features needed for user needs.
Include inputs, outputs, and behavior of the system, ensuring that it supports essential business processes.

Non-Functional Requirements

Define how the system performs regarding attributes like speed, security, and usability.
Measurable constraints that influence system quality, including performance effectiveness, reliability, and scalability.
Categories include performance, security, usability, maintainability, and compliance with regulations.

Importance of Requirements in Analysis

Both functional and non-functional elements are critical for creating a well-rounded system that meets user and business needs.
Functional requirements ensure the system offers necessary features, while non-functional requirements ensure operational effectiveness under varying conditions.
