When developing new parts, there's always a chance of 'R&D Failure'. This means the upgrade might not deliver the expected performance or could even be delayed. You can invest more resource points to reduce the risk of failure, which is often a worthwhile investment for critical upgrades. Prioritize 'Major' upgrades over 'Minor' ones when you have the resource points. Keep an eye on the 'Regulation Changes' for upcoming seasons, as these can reset certain R&D trees and require you to adapt your development strategy.
