This book provides a structured introduction to the foundational disciplines of software engineering. It guides readers through the essential processes and practices required for effective software development and design. The content is organized into key areas of modern software technology. It begins with the fundamentals of software project management, covering strategic planning topics such as requirements analysis, effort estimation, and the selection of procedural models. The text further explores operational project control, including task management, schedule and budget control, and change request handling, as well as risk and quality management. A significant section is dedicated to the transition from software architecture to detailed software design. Readers will learn about the principles of software architecture, including defining system boundaries, selecting architectural patterns, and considering non-functional requirements. This is followed by practical guidance on designing modules and components, applying design patterns, and creating data models. Furthermore, the book addresses practical software development and quality assurance. It covers implementation methods like establishing coding standards, using version control systems, and conducting code reviews. Strategies for software testing, from component and integration tests to acceptance testing, are also detailed. The final part of this section discusses processes for delivery and operation, such as building CI/CD pipelines and monitoring applications. The publication concludes by focusing on how to communicate and collaborate effectively within development teams. It presents methods for productive meetings, asynchronous communication, and creating and maintaining technical documentation. The aim is to equip readers with the knowledge to manage, document, and successfully deliver software projects through a comprehensive understanding of software engineering principles.
