programsshape

Programsshape is a conceptual framework used in software engineering to describe the overall architectural form of a software program. It focuses on how a program is decomposed into modules, how these modules interact through interfaces, and how data and control flow through the system. While not a formal standard, the term is used in theoretical discussions and in some analysis tools to discuss a program’s structural characteristics.

Key aspects of programsshape include modularity, boundaries between components, layering, and the balance between cohesion and coupling. It emphasizes the shape of a program's dependencies and the paths by which data moves between modules, often captured using diagrams such as module dependency graphs and call or data-flow graphs.

Relation to other concepts: programsshape complements software architecture and design patterns. It differs from code metrics that measure local properties like cyclomatic complexity; instead, it focuses on the global organization of a program. It can be used alongside interface design to guide refactoring and evolution.

Applications and practice: Practitioners examine programsshape during architecture reviews, onboarding, or when planning large-scale changes. Techniques include architecture recovery from legacy code, static analysis to identify modules and interfaces, and model-driven representations of the system. A clear programsshape can aid maintainability, testability, and scalability.

Status: There is no single governing standard for programsshape. The term appears sporadically in academic literature and industry discussions as a descriptive concept rather than a formal methodology. See also software architecture, modular programming, dependency graphs, and design patterns.
