jettison

This term carries a strong sense of urgency and necessity, evoking the image of a desperate attempt to save a vessel by sacrificing its cargo. It implies a decisive, often irreversible action taken to prevent a larger catastrophe, such as sinking or crashing. When used in a business or personal context, it suggests a strategic shedding of dead weight. It is more forceful than simply "changing" a plan; it implies that the previous idea was a burden or a liability that had to be completely cast aside to ensure survival or progress.
