What aspect does NOT contribute directly to optimizing IT performance?

Optimizing IT performance involves various practices, and while regular employee training is essential for overall organizational efficiency and capability, it does not directly contribute to optimizing IT performance metrics like establishing performance baselines, collecting performance data, or setting measurable performance targets.

Establishing performance baselines involves determining the expected level of performance under normal operating conditions, which serves as a reference point for measuring improvements or declines in performance. Collecting performance data is vital for understanding how systems are currently performing, identifying bottlenecks, and making informed decisions about improvements. Setting measurable performance targets helps in defining clear goals that the IT systems must achieve, allowing for better tracking and accountability.

While employee training undoubtedly enhances skills and may lead to improved performance indirectly, it does not have a direct impact on specific IT performance metrics and optimization strategies. In contrast, the other options are integral to the actual measurement and management of IT performance.
