Which principle involves improving management capabilities while also being mindful of costs?

The principle of aiming for high efficiency is focused on enhancing management capabilities while being cost-conscious. In a business context, high efficiency refers to the optimal use of resources to achieve the desired outcomes without unnecessary expenditure. This involves streamlining processes, reducing waste, and ensuring that staff and resources are utilized to their fullest potential.

By prioritizing efficiency, a supervisor can implement better management practices that not only improve the workflow and productivity but also maintain or reduce operational costs. This is especially vital in a retail environment like Uniqlo, where managing inventory, staffing, and customer service efficiently can significantly impact profitability.

In contrast, other choices imply different priorities. Being super alert pertains to vigilance and awareness, which, while important, does not directly address cost management alongside capability improvement. Making things come alive emphasizes engagement and vibrancy in operations, but does not specifically relate to efficiency or cost consciousness. Finally, staking everything on results might suggest a high-risk, results-oriented approach without the balance of cost-effectiveness, which may not always lead to sustainable management improvements.
