Suite scope and membership

Engineering DPF Suite brings together domain pattern languages for developing engineered systems and the work, organizations and capabilities needed for them. It serves practitioners choosing and improving methods across these fields, using FPF’s shared concepts.

Current scope. Under this purpose, the Suite includes the DPF series named in Published DPFs, together with the Engineering DPF Suite Reference series. This section and the declared list are the current Suite identity and membership account. Each product keeps its own field boundary, readers, methods and dated editions. The list links available editions; the ecosystem catalogue describes the same products alongside the other FPF publications.

Include a DPF when its accepted product boundary and published pattern language supply a useful contribution to this common purpose, its relevant FPF dependencies are stated, and readers can reach its admitted edition and conditions of use. Record inclusion by updating this declared list when that product decision takes effect. A first accepted publication can implement the product and Suite-inclusion decisions together. Subsequent editions are admitted under the product’s own rules; changing an edition or its availability leaves the product’s Suite membership in place.

Review the scope when new practitioner needs, changed foundations or a product’s limitations alter its contribution. A limitation calls for an explicit warning and a decision to repair, remove or replace the affected contribution. A dated removal ends membership; preserve the earlier fact for readers of older editions. If a product series ends or changes identity, its former membership ends and the replacement needs an inclusion decision.

Adding, removing or revising products preserves this Suite while its common purpose, inclusion rules and identity conditions remain. A change outside that scope identifies another Suite. If the shared purpose can no longer be served, decide whether to restore the collection or retire it; an empty or one-product interval needs an explicit restoration or retirement decision. State any continuing maintenance or future-availability commitment separately from this scope decision.
