Which type of report focuses on operational efficiency and bottlenecks?

Process metrics focus specifically on operational efficiency and identifying bottlenecks within organizational processes. These metrics provide quantifiable data that help assess how effectively a process is functioning and where improvements can be made. By analyzing process metrics, organizations can gain insights into various aspects such as cycle times, resource utilization, and throughput, which are essential for understanding operational performance.

In contrast, other options do not specifically concentrate on operational efficiency. Business value reports may emphasize strategic contributions and overall impact rather than focusing on the efficiency of processes. Bar charts, while useful for data visualization, do not inherently provide insights into operational efficiency without accompanying metrics. Process models illustrate how a process is designed but do not provide quantitative data about performance or bottlenecks. Thus, process metrics are the most appropriate choice for addressing issues related to operational efficiency and bottlenecks.
