ISO Nonconformity Tracker.

Paste your nonconformity register with grade, clause, due date and closure date. Set the as-of date and the tool shows which items are overdue, due soon or were closed late, and counts them by grade.

Register

Leave Closed blank for open items. Dates as dd/mm/yyyy or yyyy-mm-dd. Grades are whatever your system uses, such as Major, Minor or Observation.

Closure timelines depend on your certification body, your own procedure and the grade. Use the dates agreed with them; nothing here is a prescribed period.

Days: for open items, days left to the due date (negative if overdue). For closed items, days after the due date (negative if early).

A register is only useful if someone reads the dates.

Nonconformities rarely fail because they were not raised. They fail because the due date passed quietly. Sorting by status puts overdue items first, so the review meeting spends its time on what is late, who owns it and whether the date needs to be renegotiated with the certification body. Items closed late are worth a look too: they show where the process is slow even when it finishes.

How the status is worked out

An item with a closure date is Closed on time if it closed on or before the due date, and Closed late if after. An item with no closure date is Overdue when the due date is before your as-of date, Due soon when it falls within the window you set, and otherwise Open.

Items with no due date show as Open with no due date, so they are not lost. The summary counts items by grade, with open and overdue totals for each.

The list is sorted with overdue items first.

Worked example — supplier evaluation

A major nonconformity due on 31 August 2026, still open, with an as-of date of 17 October 2026.

Common mistakes

Closing on a corrective action plan, not on evidence
Record the closure date only when the action is implemented and the evidence has been reviewed.
Moving due dates without a record
If a date is extended, note who agreed and why, so overdue counts stay meaningful.
Mixing grades from different schemes
Keep one set of grade names in the register so counts by grade make sense.
