Analyze production efficiency by comparing the flow of WIP items across different stages of the manufacturing process. Include data on lead times, idle times, and the average time taken to move between stages. The output should highlight stages with the longest delays and offer suggestions for improvement. Use [LeadTime], [IdleTime], [AverageTime], [Stage], and [ProductionLine] as placeholders. The report should include graphs showing time taken at each production stage and identify stages that impact overall production throughput.
