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

Key obstacles that can disrupt the balance between responsiveness and efficiency in a supply chain include demand variability, which can lead to overstocking or stockouts, and supply chain disruptions caused by natural disasters or geopolitical issues. Inefficient communication and information flow between partners can hinder quick decision-making, impacting responsiveness. Additionally, rigid processes and lack of flexibility in operations can prevent timely adjustments, ultimately affecting both responsiveness and overall efficiency.
