Which tool is likely to increase productivity in operations?

The calculator is likely to increase productivity in operations by significantly speeding up the process of performing mathematical calculations that are crucial in various operational tasks. In environments where quick, accurate computations are necessary—such as budgeting, forecasting, and inventory management—a calculator allows for rapid processing of numbers, enabling employees to focus on higher-level strategic decisions rather than being bogged down in tedious arithmetic.

Furthermore, calculators reduce the risk of human error that can occur with manual calculations, leading to more accurate results and minimizing the time spent on correcting mistakes. This efficiency can enhance overall workflow and lead to faster decision-making processes, ultimately contributing to improved productivity within the operations.

In contrast, the other tools—such as telegraphs, paper documents, and manual filing systems—are less efficient in promoting productivity in a modern operational context. While these tools served important roles in their time, they lack the speed and accuracy of a calculator, which is crucial for the demands of current business operations.
