Status: OUT
Systematic variation management extends across the full object lifecycle: the composition paradigm's prerequisite stack enables variation management from the moment of creation (creational patterns determining what is instantiated) through structural adaptation (interface coupling management) to behavioral modification (four-dimensional modification space) — demonstrating that variation is managed temporally across the lifecycle, not just structurally at a single point in time.
