Programmmerkmal

Programmmerkmal is a term used in software engineering to describe a characteristic or property of a software program. It denotes a specific aspect of the program’s behavior, capabilities, or operating conditions and is used to describe and communicate the features of a software product in a structured way. The term emphasizes that the feature pertains to a particular program rather than a general concept.

In practice, Programmmerkmale are often categorized into functional and non-functional areas. Functional Programmmerkmale refer to concrete capabilities the program performs, such as user management, data input, or report generation. Non-functional Programmmerkmale describe qualitative properties like performance, reliability, security, usability, compatibility, and maintainability. Some Properties may be configurable through settings, plugins, or APIs, allowing the program’s behavior to adapt to different use cases.

Examples of Programmmerkmale include multi-user support, export options (CSV, PDF), API access (REST or GraphQL), offline mode, localization and internationalization, role-based access control, responsive user interfaces, and predictable resource usage. In development and management processes, Programmmerkmale serve as a basis for requirements specification, architectural planning, and quality assurance. They provide a reference catalog for aligning requirements, design decisions, testing, and acceptance criteria, as well as for comparing different versions or products.

Relation to other concepts: Programmmerkmal is often used interchangeably with terms like Funktionalität or Eigenschaft, though it typically implies a broader scope than a single function. It can encompass both what the program does and how well it does it, including configurability and constraints.
