Software development is the structured process of creating, designing, deploying, and supporting software. It involves a series of steps that result in the development of functional and efficient applications tailored to solve specific problems or meet user requirements. In information technology (IT), software development is fundamental to digital transformation, enabling businesses and individuals to perform tasks with greater efficiency, security, and scalability.
Software development spans various domains, including web applications, mobile apps, enterprise systems, embedded software, cloud computing, and artificial intelligence. The goal is not only to create software but to maintain and improve it over time.
This is the foundational phase where stakeholders, clients, and development teams collaborate to gather and define the software’s requirements. Clear documentation is created, outlining functional, non-functional, technical, and business needs.
Architects and developers design the software system’s structure, specifying architecture, user interfaces, database designs, and system integration points. Tools like UML diagrams and wireframes are often used.
In this phase, developers write code using programming languages and frameworks based on the approved design. This is the core technical activity, where the actual logic and features are developed.
Testers validate the functionality, performance, security, and usability of the software. It includes unit testing, integration testing, system testing, regression testing, and user acceptance testing (UAT).
The final product is released into a live environment. This phase can include beta releases, full production launches, and rolling updates. DevOps practices streamline deployment and ensure continuous delivery.
Post-deployment, software requires regular updates, bug fixes, and enhancements. Ongoing support ensures the software remains functional, secure, and aligned with user expectations.

A linear and sequential model where each phase must be completed before moving to the next. Suitable for projects with clear, unchanging requirements.
A flexible, iterative approach that emphasizes collaboration, customer feedback, and rapid releases. Agile breaks development into sprints, promoting continuous improvement.
A subset of Agile, Scrum organizes work into fixed-length sprints with defined roles like Product Owner, Scrum Master, and Development Team. It encourages teamwork, accountability, and incremental progress.
DevOps integrates development and operations teams to automate and streamline the software delivery process. Key practices include continuous integration, continuous deployment (CI/CD), and infrastructure as code.
Inspired by lean manufacturing, this approach focuses on reducing waste, improving efficiency, and delivering value quickly. It emphasizes fast delivery, quality, and customer-centric design.
RAD emphasizes quick development and iteration with minimal planning. It suits projects where speed is prioritized over strict structure.
Popular languages include Java, Python, JavaScript, C#, Ruby, PHP, Kotlin, and Swift. The choice depends on the application type and platform.
