PHY.Preface:3.3 - Constituent actions in ongoing work

Acquiring a reading can be part of testing a physical account while the discriminating investigation is already under way. If rival accounts agree at equilibrium but differ during a transition, a settled-value observation cannot answer the same question: its timing must change. Instrument use, the mathematical consequence and knowledge of the accounts can be available separately while the coordination of intervention and observation is missing. The domain’s observation Method supplies that intermediate contribution and its equipment conditions.

FPF B.1.5.EW helps recover these constituent–whole connections; B.1.5.RS examines a proposed replacement. Use the parts of the vertical that can change the present result. A Method described here can require additional capability, available support and compatible resources at other grains.
