Reading dwell time in purchase orders without drowning in charts

When a purchase order sits between approval and release, the delay rarely shows up as a single red flag. It appears as a quiet stretch of calendar days that only becomes visible when you line up requisition, approval, PO print, and goods receipt for the same order family.

Start with a glossary your buyers and AP already use. Name five stages at most: request, approve, release, receive, settle. Pull a sample of thirty to fifty orders from one category rather than the entire ledger. For each order, note the date the stage was entered and the date it left. The difference is dwell time—not a score, just elapsed days.

In Thai manufacturing and distribution groups we work with, approval dwell often clusters around holiday weeks and around cost-center owners who travel. Receipt dwell clusters when warehouses batch-scan at shift end. Those patterns matter more than a single average cycle figure.

Present the sample as a simple stage strip with median and high-dwell callouts. Leave the decorative charts for later. Leadership usually asks two questions: which stage grew, and which suppliers or cost centers sit in the long tail. Answer those first.

If your extracts lack clean stage timestamps, reconstruct from status-change logs or from email approval stamps for a smaller sample. A partial but honest map beats a polished board built on guessed dates.
