When is it ineffective to use suggest runs?

Suggest runs are typically employed to optimize delivery times and enhance customer satisfaction. However, when an order is already late, using suggest runs becomes ineffective. This is because the primary goal of suggest runs is to propose the most efficient route or delivery schedule ahead of time, allowing for proactive adjustments. In situations where an order is already late, the priority shifts to addressing and resolving the delay rather than generating additional routes.

In this context, the other scenarios—when all drivers are busy, during peak demand, and when map services are down—still allow for the utility of suggest runs, as they can assist in planning future deliveries or adjusting resources even under challenging conditions. For instance, peak demand may warrant suggest runs to better manage the expected high volume of orders, while being aware of busy drivers can help set expectations. Similarly, although map services being down complicates the situation, it doesn't necessarily render suggest runs completely ineffective; it requires a different approach to utilizing available data for routing.
