Which of the following would likely NOT be used as a tactic to improve short-term business performance?

Investing in new technology typically requires a significant upfront investment and a longer time frame to realize returns, making it less suitable as a tactic for improving short-term business performance. In contrast, tactics like reducing operating costs, increasing advertising spend, and optimizing workforce scheduling can lead to immediate financial benefits or sales increases. Reducing operating costs can improve margins quickly, increasing advertising can boost sales promptly, and optimizing workforce scheduling can improve efficiency and reduce labor costs right away. Therefore, investing in new technology is not aligned with a focus on quick, short-term gains, and thus would likely not be used as a tactic for that purpose.
