Why might engineers continue developing two competing technologies before choosing between them?

In systems engineering, engineers may continue developing multiple competing technologies simultaneously to avoid making a premature choice between them. This approach is particularly common when a formal systems engineering organization is in place, allowing for the parallel exploration of different technical paths until it becomes clear which option is superior or whether each technology serves a distinct niche in the marketplace.1

By maintaining these parallel development lines, engineers can monitor the technical frontier and gather necessary data to mitigate the risks associated with long-term projects, where both technology and service demands may evolve significantly over time. This strategy ensures that the final selection is based on a more complete understanding of the available options rather than an early, potentially flawed decision.1
