Records and traceability depend on habit: a fix for medical device makers

A distributor's email lands on a Monday. A hospital has flagged an infusion set with a peeling pouch seal. It wants to know which shift sealed lot 2417, at what jaw temperature and dwell, and from which reel of film. The quality engineer pulls the sealing log. Three shifts, one handwriting. Every temperature reads the same. The supervisor admits the night crew filled the column at seven in the morning, from memory. A month later the engineer, two years into a job she liked, takes a post with a larger firm.

That chain, from a blank box to a lost engineer, is the second pattern on our page for medical device and equipment units. Buyers expect each lot to trace back to the people, machines and materials behind it. Entries go missing when operators are new or rushed. The cure is less about forms than about habit. It turns on how people are inducted, where the sheet hangs and whether a supervisor reads it while the ink is wet.

• Whole columns of a pouch-sealer log in one ballpoint, written at shift end.
• Ticks against dwell time and jaw temperature where the dial values belong.
• Whitener over the cavity number on the route card, so nobody can tell what was first written.
• Thermal-transfer label counts that refuse to reconcile: printed, used and destroyed never add up to the issued roll.
• Bar heat numbers copied from the previous lot because the mill certificate was locked in the office almirah.
• Steriliser load charts with the indicator strip pasted on the wrong page, and initials of an operator who was on leave that day.

The visible cost is a shrink-wrapped pallet in the quarantine cage while someone sorts and re-inspects it. A buyer's query that takes a week to answer costs more, because it shows the buyer how the unit really runs. The quieter bill is paid in people. Quality and process engineers hired to improve yields end up chasing signatures. They spend evenings rebuilding route cards and photostatting load charts before a customer visit. Few stay long in a role that turns them into clerks for gaps they did not leave.

• They learned the sheet from a hurried colleague. Induction covered gowning and safety, then a busy operator showed the log in two minutes, shortcuts included.
• The sheet was designed in the office. Its columns follow the quality manual, not the order of work at the sealer or the lathe.
• The clipboard hangs far from the work. If it lives in the supervisor's cabin, entries wait until someone walks over.
• Nobody looks until the end. A supervisor who checks only at shift close finds gaps after the person who left them has gone home.
• Admitting a miss feels risky. Where a blank earns a public scolding, operators fill it with a guess.
• Temporary hands skip induction. Tender-season helpers go straight onto a line and copy whatever they see.

• Pull ten recent route cards or batch records at random and go through each with the operator who wrote it.
• Mark every entry made after the event, judging by handwriting, ink or timing.
• Walk from each workstation to wherever its sheet lives, and count the steps.
• Ask new joiners who taught them the records, and how long that took.
• Ask the quality engineers how many evenings last month went on rebuilding records.

1. 1

   Redesign the sheet with the people who fill it

   Sit an operator, a supervisor and the quality engineer together. Put columns in the order the work happens and strike out anything nobody reads.

2. 2

   Put the sheet where the hand is

   A clip holder at the sealer, the Swiss lathe or the test bench, with a pen tied on with twine. Entries happen when the reading is in front of the eye.

3. 3

   Teach records at induction with a practice sheet

   Every joiner fills a dummy route card from a real job. The trainer corrects it with them before they touch a live lot.

4. 4

   Check at the bench while the ink is wet

   Supervisors initial each sheet at the workstation at two fixed points in the shift. A gap found at noon can still be closed honestly.

5. 5

   Set one correction rule and teach it

   A single line through the error, the right value beside it, initials and date. No whitener, no overwriting, no torn pages.

6. 6

   Make an early admission safe

   An operator who reports a missed reading within the shift is thanked, not scolded. A guess discovered later is the serious matter.

7. 7

   Review a sample each week, together

   The quality engineer reads five records with the operators who made them and shows what a clean one looks like.

Engineers in quality and process roles stay where their work improves the product. When records hold at the bench, their week moves from chasing to analysis: yield trends, process changes, supplier faults. That shift is a retention measure in its own right. Pair it with a visible next step, as set out in our piece on growth paths for device engineers. The role then becomes one a capable engineer wants to keep.

At their next review, ask your quality engineers one blunt question. How many evenings last month went on rebuilding records before a visit? The answer tells you how far the habit has really taken hold.

Habits survive when induction teaches them and supervisors reinforce them. See the onboarding pages for disposables makers and medical plastics moulders. Both show record training inside the first weeks on a clean line. Our answer on teaching operators record keeping and sign-off covers the teaching itself. Onboarding process design is where we usually begin with a unit that keeps finding blank columns.
