FIN.Preface:12 - Relations

Supplying language or method	Contribution used here	When to obtain it
Management Accounting, MA 1.0	Resource and cost accounts, capacity and assignment meanings, reporting–cash reconciliation, purpose-qualified forecasts and account use.	A required accounting result is missing or its meaning is disputed; primarily FIN.3–4, with reuse elsewhere.
Financial Domain Modeling, FDM 1.0	Parties, financial positions, conditional instruments, descriptions and actual event effects.	A financial object’s meaning or effect is unresolved; particularly FIN.1–2, FIN.8, FIN.10 and FIN.13–16.
Operations Management	Feasible operating plans, capacity and service consequences; coordination under existing authority.	A financial alternative’s operating feasibility or allocation of work and resources is unresolved.
Organization Change Engineering	Changes to organizational responsibilities and decision rights.	FIN.19 exposes a needed change to that arrangement.
FPF B.1.5.EW	Recovery of how constituent actions perform encompassing work.	A calculation or another local operation is known, but its place or needed conditions in the financial work remain unclear; FIN.2 gives an example.
FPF C.11 and C.11.DUA	Choice among available alternatives; appraisal of advice and evidence demands by receiving use.	The local choice or the value of advice or demanded inquiry needs that general method.
FPF C.32.MWA and C.36	Several interacting structures of practice; cultural continuation and deliberate change.	FIN.19 or FIN.20 needs the corresponding reusable method.

These are contribution relations, not a mandatory reading order. Reopen a dependency when its supplying result or the receiving use changes materially; unchanged adequate results remain usable.
