What describes the historical Russian method of vehicle maturation contrasting with the current leader in reusability?

Long, methodical cycles involving extensive ground testing before flight

The historical approach to developing reliable spaceflight hardware in Russia, exemplified by the Soyuz program, favored a deliberate and methodical development cadence. This involved lengthy periods dedicated to ground testing and maturation processes before the hardware was authorized for flight. This patient approach resulted in highly reliable vehicles. In contrast, the current leader in achieving routine reusability (implied to be SpaceX) has often utilized a much faster, iterative development cycle, characterized by a high tolerance for in-flight failures as a means of quickly solving complex engineering problems related to landing and reuse. For Russia to bridge the gap, it must successfully integrate the high-speed, risk-tolerant iterative testing necessary for reusability while preserving its traditional institutional rigor.
