Software Engineering Introduction

Accuracy: Produce software that meets the specification (SRS).
Reliability: Ensure the product performs correctly and consistently.
Testability: Make the system easy to test so defects can be found early.
Reusability: Design components that can be reused in other projects.
Maintainability: Allow easy updates and modifications over time.
Cost-effectiveness: Deliver value without excessive cost.
Efficiency: Implement solutions that use resources (time, memory) well.

What is Software Engineering?

Software engineering is composed of two terms: software and engineering.

Software refers to the set of instructions that tells a computer what to do and how to perform tasks.
Engineering involves designing and building systems in an effective, repeatable way.

Software engineering applies engineering principles and systematic methods to develop reliable, maintainable and high-quality software products.

A software engineer is someone who analyses user requirements, designs solutions, implements code, verifies behavior and maintains the product.

Delivers software that satisfies user requirements and improves user satisfaction.
Produces flexible and modular products that adapt to change.
Encourages clear documentation (e.g., SRS) for better communication.
Uses cost-effective processes that reduce waste and rework.
Applies proven methodologies that save development time.
Creates structured teams and workflows for a comfortable working environment.
