The document discusses using data and metrics to provide a real performance story for planning applications. It advocates for continuous benchmarking and monitoring at the individual application level to understand trends, customer satisfaction, and how planning services are delivered. Graphs and charts are presented showing potential metrics like processing times, approval rates, withdrawn applications, and customer survey results that could be tracked for multiple councils to benchmark performance. The goal is to move beyond annual snapshots and understand performance as a continuous process for improving customer outcomes.
