What are the trade-offs between safety, performance, and efficiency in design?

Factors of Safety - FOS - are a part of engineering design and can for structural engineering typically be expressed as FOS = F fail / F allow (1) The typical safety factor for pressure vessels, often referred to as the Design Factor, usually ranges from 1.5 to 4.
