SIE.12:1 - Problem Frame
Use this when independently governed participants depend on shared semantic modules and need an arrangement for maintaining them. A typical failure is a changed shared term whose consumers cannot determine who could approve the change, which meaning their interface uses, or how to migrate.
Start with one module and the uses that actually depend on it. Establish its scope, who can decide its content and release, and how its users can obtain an identifiable maintained edition. The first useful result is an agreement through which those participants can make and use a concrete module change.
The object is the shared maintenance and reliance arrangement for semantic modules. The gain is continued reuse with explicit local commitments, contribution rights, dependencies, and change consequences. A compatibility claim covering additional users needs support for those users’ relevant reliance.
A team or a pair maintaining one interface can use its ordinary model and interface agreement when that suffices. A repeated file or shared repository alone does not establish a commons that needs this Method.
