Green Energy Solutions would like to become more competitive by providing a better service experience...

This question addresses the trade-off between Customer Experience and Schedule Optimization.

Reducing the arrival window (e.g., from 4 hours to 2 hours) is a common strategy to improve customer service. Customers prefer shorter wait times and more precise appointments. However, a consultant must identify the technical impact of this business decision.

Option B is correctbecause it acknowledges the benefit (customer experience) while correctly identifying the risk. Smaller arrival windows serve as tighter constraints on the scheduling engine (Optimization). The engine has less "wiggle room" to shuffle appointments, which can lead to lower overall utilization or higher travel times.

Option C is incorrect because reducing the windowdecreases(restricts) flexibility for optimization, it does not increase it.

Options A and D suggest increasing the window to 8 hours. While this is great for the optimization engine (maximum flexibility), it is generally considered a poor customer experience to ask a prospect to wait all day (8 hours), contradicting the business goal of being "more competitive."
