Use cases
Functional modeling
Requirement management tools

Readers learn how poorly defined requirements can lead to cost overruns, delays, defects, and project failure.

The emphasis is on transforming user needs into structured and measurable software requirements.

Part II — Software Design Principles and Techniques

Once requirements have been identified, the next challenge is designing a system that can satisfy those requirements effectively.

Part II introduces the principles and techniques used to transform requirements into software designs.

The book explains important design principles such as:

Abstraction
Modularity
Encapsulation
Cohesion
Coupling
Separation of concerns
Design strategy

These principles help developers create software that is easier to understand, test, modify, and maintain.

Software Architecture

Modern applications often consist of multiple components and services. Good architecture provides the structure needed to manage this complexity.

The book introduces software architecture and explores several important architectural styles, including:

Layered architecture
Client-server architecture
Microservices architecture

Readers learn how architectural decisions affect:

The section also introduces approaches to documenting software architecture and communicating architectural decisions.

Component-Level Design

The book then moves from high-level architecture to detailed software design.

Readers explore:

Structured design
Function-oriented design
Data Flow Diagrams (DFDs)
Structure charts
Object-oriented design
Design patterns

Important design patterns such as Factory, Singleton, Observer, and MVC are introduced as reusable approaches to common software design problems.

The goal is to help readers develop the ability to select appropriate design techniques instead of approaching every software problem from scratch.

UI, UX, and Human-Computer Interaction

Software quality is not determined only by backend functionality.

A successful application must also provide an interface that users can understand and operate effectively.

The book introduces:

UI design principles
UX fundamentals
UI vs. UX
Prototyping
Human-Computer Interaction
Usability
Accessibility

These concepts help readers understand how software design can consider both technical requirements and human needs.

Software that appears to work is not necessarily reliable software.

Testing and quality assurance are therefore critical components of professional software engineering.

Part III introduces software testing fundamentals and explains:

Testing objectives
Testing principles
Unit testing
Integration testing
System testing
Acceptance testing
Black-box testing
White-box testing
Grey-box testing

The book emphasizes that testing should be integrated into the software development lifecycle rather than treated as an activity performed only at the end.

Test Case Design Techniques

Effective testing requires more than creating random test inputs.

The book introduces systematic techniques for designing effective test cases, including:

Equivalence partitioning
Boundary value analysis
Decision table testing
State transition testing
Path testing

Understand → Practice → Analyze → Design → Test → Build → Improve

Instead of memorizing concepts, learners should try to apply them to real software projects.

For example, after studying requirement engineering, readers can create an SRS for a small application. After learning architecture, they can design the system architecture. After learning testing, they can create test cases. After studying DevOps, they can explore how the application could be deployed through an automated pipeline.

This approach turns software engineering from a theoretical subject into a practical engineering discipline.
