Programvareutvikling, or software development, is the process of conceiving, specifying, designing, implementing, testing, deploying, and maintaining software applications and systems. It includes activities from requirements gathering and architectural planning to coding and ongoing maintenance. The aim is to deliver software that meets user needs, performs reliably, scales under load, and remains adaptable to changing requirements and technologies.

Software development lifecycles describe how work progresses from idea to released product. Traditional approaches such as Waterfall follow a linear sequence, while modern practices emphasize iteration and feedback. Agile frameworks like Scrum or Kanban promote incremental delivery and close collaboration, and DevOps integrates development with operations to improve automation, delivery speed, and reliability through continuous integration and deployment.

Key roles include product owners, project managers, software engineers, testers, UX designers, and DevOps engineers. Common artifacts are requirements specifications, design documents, user stories, test plans, source code, build artifacts, and release notes. Quality assurance, security testing, and accessibility checks are typically integrated throughout development rather than left for the end.

Tools and practices support collaboration and quality. Version control systems (for example, Git), issue trackers, and CI/CD pipelines automate testing and deployment. Containerization (Docker) and orchestration (Kubernetes) enable scalable deployment. Code reviews, automated tests, static analysis, and monitoring help maintain reliability after release.

Trends include AI-assisted development, low-code and no-code platforms, cloud-native architectures, microservices, and serverless computing. Ethical considerations, data privacy, and robust security remain central. Effective software development balances speed with quality, aligning technical approaches to user needs and organizational goals.
