Introduction

What is software engineering and why is it important?

Software engineering is defined by Sommerville as "the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software" (p. 5). Software engineering aims to ensure that software systems are developed according to agreed specifications, within budget and schedule constraints, with acceptable quality levels, and that they can be modified and adapted to changing requirements.

Software engineering is important because software systems are ubiquitous in modern society, affecting almost every aspect of human life. Software systems are used for communication, education, entertainment, business, health care, transportation, security, defense, science, engineering, and many other domains. Software systems are also complex, involving many components, interactions, dependencies, constraints, requirements, stakeholders, risks, and uncertainties. Therefore, software engineering is needed to manage this complexity and ensure that software systems are dependable, usable, maintainable, and evolvable.

It also introduces some concepts such as prototyping, rapid application development (RAD), software reuse, or service-oriented architecture (SOA).

Agile software development and its principles

This section introduces agile software development as an alternative approach to plan-driven methods that emphasizes flexibility, collaboration, and customer satisfaction. It also explains what are the four core values and the twelve principles of agile software development, as stated in the Agile Manifesto. It also gives some examples of agile methods such as Scrum, Kanban, Lean, or Crystal. Plan-driven and agile processes compared

This section compares and contrasts plan-driven and agile processes in terms of their characteristics, advantages, disadvantages, applicability, and compatibility.

Context, interaction, structural, and behavioral models

This section explains what is system modeling and why it is useful for software engineering. It also distinguishes between four types of models that can be used to represent different aspects of a system: context models show the system boundaries and its relationships with other systems; interaction models show how the system interacts with its environment; structural models show the organization and composition of the system components; and behavioral models show how the system changes its state in response to events.
