Softwareentwicklungszyklen

Softwareentwicklung, the German term for software development, refers to the discipline and activities involved in creating software products. It encompasses conceiving requirements, specifying system behavior, designing architectures, implementing code, testing, deploying, and maintaining software to meet user needs within constraints such as time and budget.

A typical software development life cycle (SDLC) includes requirements gathering, system design, implementation, verification, deployment, and ongoing maintenance. Projects may follow rigid sequential models or adopt iterative and incremental approaches to manage complexity and risk.

Common development methodologies include the traditional waterfall model, incremental and iterative processes, and agile approaches such as Scrum and Kanban. DevOps integrates development with IT operations to shorten delivery cycles and improve automation and collaboration.

Key roles include software engineers, developers, testers, architects, and product or project managers. Artifacts produced include requirements specifications, design documents, architectural diagrams, test plans, and user manuals, along with the source code stored in version control systems such as Git.

Tools and technologies span programming languages, frameworks, integrated development environments, testing tools, and build systems. Modern practice relies on continuous integration and continuous delivery (CI/CD), automated testing, containerization, and cloud deployment.

Quality attributes such as reliability, performance, security, and maintainability guide design decisions. Common challenges include scope creep, technical debt, integration with legacy systems, changing requirements, and regulatory or standards compliance.

Software development is central to modern economies, underpinning everything from consumer applications to embedded systems. It includes open-source and proprietary approaches and emphasizes collaboration, measurement, and governance to deliver value.
