SIE.Preface:3 - Pattern relations do not prescribe a lifecycle

The patterns have information dependencies, not one mandatory calendar sequence. SIE.1 and SIE.2 often expose the first stop. A practitioner may enter SIE.5 when the use and source inventory already exist, SIE.8 when a realization choice is current, or SIE.10 when an existing interface needs validation. Discovery, alignment, mapping, implementation, and testing can iterate.

SIE.3 supplies a qualified reused or developed model when adequacy is unsettled. SIE.11 follows a changed semantic premise to the results that actually relied on it; a compatible reference repair can finish directly. SIE.12 supplies the arrangements needed by actual shared-module users. A known adequate model, an unchanged use, or one local interface can continue without performing those further Methods.
