Which of the following is a method to improve process efficiency?

Process streamlining is an effective method for improving process efficiency as it involves analyzing and optimizing workflows to eliminate unnecessary steps, reduce waste, and enhance productivity. This method focuses on evaluating current processes and making adjustments to ensure that each step adds value, thereby achieving better outcomes in a shorter time frame.

Streamlining often includes the adoption of best practices, automation of repetitive tasks, and better resource allocation. These changes not only result in time savings but also contribute to improved quality and satisfaction for both employees and customers.

In contrast, options like increased staffing, higher inventory levels, and lengthened work hours may create a temporary increase in capacity but do not necessarily lead to efficiency improvements. Increased staffing can lead to complexities in management and coordination, higher inventory levels can result in excess costs and resource waste, and lengthened work hours can lead to employee burnout and reduced productivity over time. Thus, streamlining processes is the most sustainable approach to enhancing efficiency.
