Which Appian architecture component is responsible for maintaining process reports?

The component responsible for maintaining process reports in Appian is Process Analytics. This component plays a critical role in providing insights and visualizations of process performance and operational data. It aggregates data from various processes and presents it in a way that allows users to understand process efficiency, monitor key performance indicators, and identify areas for improvement.

Process Analytics enables users to generate reports that help analyze process execution metrics, such as completion times, variances, and bottlenecks. This functionality is essential for organizations looking to optimize their workflows and ensure that processes are running smoothly.

Other components mentioned do serve important functions within the Appian architecture, but they do not specifically focus on maintaining process reports. For instance, the Process Execution Engine is responsible for executing process instances, while the Appian File System manages document storage. The Search Server focuses on indexing and searching through various content in Appian. These components support various aspects of the platform but do not directly relate to the creation and maintenance of process reporting, which is the key function of Process Analytics.
