SYSE.53:1 - Problem frame

Use this pattern when a set of independently released components must work together and selecting each component separately leaves an unresolved dependency, shared meaning or interface condition. A plugin update may require a library that another plugin cannot use. Two method accounts may rely on incompatible editions of a definition. A downloaded set can therefore be complete as a collection and still unsuitable for the consuming task.

The immediate result is a selected component configuration with reasons for its supported relationships, an explained conflict within the examined alternatives, or the precise premise or unfinished search that prevents selection. Begin with what the consumer actually needs to do. Derive requirements and sharing conditions from that use, resolve the determinate part, and retain qualifications that calculation cannot supply.

The wider field is engineering independently changing components. This pattern addresses the digital branch: executable packages, their necessary data and definitions, and independently released documentary components. Its object is the proposed configuration and its supported relationships; its move is to select or revise that configuration before realization. The contents of a document, the software that reads it and the machine performing the task remain different things. Provisioning the selected environment and deciding the professional matter described by its documents need their own results.

Use an already adequate fixed composition directly. If the question is how to rebuild known inputs, enter SYSE.30; if it is how to provide known working conditions, enter SYSE.33. A source sufficient for one reading does not need a package catalogue or resolution exercise.
