Management Consultant: A recent industry survey of logistics firms showed that those firms adopting centralized algorithmic routing software experienced a 20% reduction in average delivery times over the past year. In contrast, firms relying on traditional human dispatchers saw only a 5% reduction. Therefore, the transition to algorithmic routing software is directly responsible for the superior improvement in delivery efficiency among these firms.
Which of the following, if true, most seriously weakens the management consultant's argument?
- AThe 5% reduction in delivery times achieved by firms using human dispatchers represented a larger absolute number of minutes saved than the 20% reduction achieved by firms using the software.
- BThe algorithmic routing software automatically accounts for real-time traffic conditions, a task that human dispatchers struggle to perform efficiently.
- The logistics firms that adopted algorithmic routing software were predominantly those that had recently replaced their delivery vehicles with newer, significantly faster models.Answer
- DFirms relying on traditional human dispatchers actually saw a reduction in average delivery times of roughly 20% over the past year.
- EMany logistics firms that adopted algorithmic routing software experienced significant declines in employee morale among their delivery drivers.
Answer
The statement indicating that the software-adopting firms predominantly replaced their vehicles with significantly faster models.
The argument concludes that the algorithmic routing software caused the 20% reduction in delivery times, based purely on the correlation that firms adopting the software experienced this reduction. The correct answer weakens this causal claim by introducing an alternative cause: the firms that adopted the software also recently acquired newer, significantly faster vehicles. This suggests that the new vehicles, rather than the software, may be responsible for the improved efficiency.
