To cut the 3-week aggregate reporting time, which set of changes should you implement?

The correct option addresses the core issues contributing to the 3-week reporting time. Increasing fleet cellular connectivity to 80% ensures more frequent and reliable data transmission from the source, reducing delays caused by intermittent connections. Moving from FTP (a batch-oriented protocol) to streaming transport allows for real-time or near real-time data ingestion, eliminating the latency of waiting for large files to be transferred periodically. Building ML analytics on the metrics enables automated processing and insights generation, significantly speeding up the analysis phase that previously took weeks. Migrating from CSV to a binary format (option 1 and 2) would optimize storage and parsing but wouldn't directly address the data transmission latency or the manual analysis bottleneck. Migrating FTP to SFTP (option 1 and 4) only enhances security, not speed. Increasing dealer local inventory (option 4) is a business decision unrelated to reporting time.
