Supply chain complexity can hurt a company's efficiency. To manage this, supply chain managers need to understand what causes complexity and take action. A study looked at different factors contributing to supply chain complexity in the drive and control industry. They interviewed top managers from manufacturers, suppliers, and customers to identify key drivers. The study also explored the importance of agility, adaptability, and alignment in supply chains. Finally, a simulation model was used to assess the impact of supply chain complexity on inventory and logistics costs.
