Definition
Experimental Restart is an engineering philosophy that advocates for throwing away existing designs and starting from first principles when progress stalls.
Why It Matters
It allows teams to escape local maxima and build radical breakthroughs, avoiding the accumulation of technical debt.
Core Concepts
- Incrementalism (The Soyuz Model): Systems are designed for performance over comfort. Components that never fail (e.g., oxygen valves) are left unchanged for decades, preserving institutional knowledge and “shaking out” all possible bugs through high flight frequency.
- Radical Innovation (The NASA Model): Scrapping old systems (Gemini Apollo Shuttle) to pursue higher performance or new mission types. This introduces “enhanced profound risk” as every restart begins the “bug-finding” cycle from zero.
- How to read: “The progression from Gemini to Apollo to the Space Shuttle.”
- Meaning: Each arrow marks a deliberate program reset—new hardware, new teams, new failure modes—rather than continuous refinement of one lineage.
- Experimental Risk: The danger of flying a vehicle only a handful of times. Without high-frequency use, “black swan” technical failures are harder to predict.
