Abstract :
Amdahl\´s performance law is a useful conceptual and pedagogical tool for imparting key ideas about performance limits and the importance of balanced system design to students and practitioners in the field. The weakest-link maxim of reliability engineering can be expressed in terms of an identical formula, giving it a quantitative basis and thus making it more convincing. Calling it "Amdahl\´s reliability law" stresses the fact that it follows directly from Amdahl\´s speedup formula.
