  "account": "DecodeVinValuesBatch jobs in UX design present a challenge when some VINs fail to decode, resulting in a mix of successful, empty, and invalid outcomes. NHTSA's batch decode tool allows for multiple VINs to be sent in a single call, but the response is not uniformly positive or negative. The post focuses on progress and partial-failure UX for batch jobs, aiming for determinate progress, honest per-VIN outcomes, and UI copy that doesn't falsely claim full success when errors exist.\n\nBatch jobs consist of three layers: client queue, upstream call(s), and row mapping. Current progress tracking methods only monitor HTTP round-trips, misleading users about the job's status. A better approach is to model the job explicitly using types for RowStatus, BatchRow, and BatchJob. This allows for a clearer distinction between queued, running, ok, empty, invalid, and error statuses.\n\nEmpty VINs should be separated from errors to help sellers and dealers differentiate between temporary issues and more significant problems. Determinate progress should be displayed as a bar based on the ratio of done to total rows, rather than elapsed time. When chunking batches, update the running progress for the active chunk and immediately apply terminal status to rows as each chunk returns. Even if the upstream API only provides all-or-nothing responses, update local invalid statuses immediately for a more accurate representation of the job's progress.\n\nWhen the job finishes with mixed results, provide a summary that includes counts of successfully decoded VINs and those requiring attention, rather than a generic \"Batch complete\" message. Implement UI patterns such as sticky summary chips, sorting failed rows to the top, per-row reason displays in plain language, and an option to export a CSV of only the failures. This approach helps reduce support inquiries and ensures users understand the job's outcome.",
  "summary": "Batch decode is where product UX either feels like a dashboard or like a frozen spinner. NHTSA DecodeVinValuesBatch lets you send multiple VINs in one upstream call, but the response is not \"all green or all red.\" Some rows decode cleanly, some return empty cores, and some never left your client because of local validation.
