What are the following key obstacles that can upset the balance between responsiveness and efficiency in a supply chain?

Key obstacles that can upset the balance between responsiveness and efficiency in a supply chain include demand variability, which can lead to overstocking or stockouts; supply chain disruptions, such as natural disasters or supplier failures, which hinder timely responses; and inadequate technology or information systems that impair real-time data sharing and decision-making. Additionally, misalignment between supply chain partners can result in inefficiencies and slow response times. Together, these factors can create tensions between the need to react quickly to market changes and the goal of maintaining cost-effective operations.
