Abstract

For nearly two decades, the discipline of enterprise systems engineering has operated under the convenient but increasingly perilous fiction that SAP landscape reliability is a static, binary state. However, the contemporary collision of conservative "Brownfield" migration strategies with the high-velocity demands of "Open IT landscape management" exposes a critical failure in traditional time-independent Markov models, which ignore the entropic accumulation of technical debt. To quantify this degradation, this study employs a "hostile" experimental topology, subjecting a hybrid S/4HANA and SAP Business Technology Platform (BTP) environment to chaotic integration friction to validate a novel Composite Time-Dependent Reliability Architecture. Empirical telemetry reveals that reliability in heterogeneous environments functions not as a constant but as a rapidly decaying variable exhibiting a distinct "sawtooth" pattern of state exhaustion where the standard semi-annual system refresh cycle proves demonstrably insufficient against the logarithmic rot induced by external API volatility. Consequently, this research proposes a fundamental shift toward a "metabolic" framework of landscape management, arguing that operational excellence requires treating reliability as a consumable resource that demands a rigorous, mathematically modelled cadence of restorative maintenance rather than mere static governance
