BackendPhasen

BackendPhasen is a conceptual framework for organizing backend software development into distinct phases. The term blends "backend" with the German word "Phasen" (phases) and is used in German-speaking software engineering discussions to describe a structured approach to backend work. The framework emphasizes early planning, clear interfaces, and deliberate handoffs between teams to improve coordination, traceability, and reliability.

Typically, the BackendPhasen sequence comprises six phases: requirements and planning; architecture and data modeling; implementation and integration; testing and quality assurance; deployment and operations; and maintenance and evolution. During requirements and planning, stakeholders define business goals, data needs, API contracts, non-functional requirements, and success metrics. Architecture and data modeling establishes service boundaries, data schemas, security models, API designs, and considerations for scalability and resilience. Implementation and integration covers the development of services, databases, messaging, and external system connections, with attention to interface stability and versioning. Testing and quality assurance includes unit, integration, contract, and performance tests, along with security assessments and proper test environments. Deployment and operations focuses on CI/CD configuration, deployment strategies, staging, monitoring, logging, and incident response. Finally, maintenance and evolution addresses monitoring, tuning, refactoring, API deprecation, and debt management to sustain system health over time.

Adoption of BackendPhasen supports better traceability of requirements to artefacts and helps align backend work with frontend needs and business outcomes. It is compatible with Agile, DevOps, or hybrid processes and can be adapted to microservices, monoliths, or serverless architectures.
