A woven shirt unit lost its collar operator after a Friday shift. The supervisor named one other hand who could run the collar, but she was on leave until Tuesday. By Monday afternoon the sleeve and cuff sections held bundles waiting for collars, and the poly bags sat unpacked at the finishing table. Ask three supervisors who else could have stepped in and you would have got three different names.
A skill matrix replaces that guessing. It is a plain grid, pinned beside the line board, that shows who has been signed off on which operation. This post gives the grid, the rating scale, the way to fill it and the monthly reading.
The grid you can copy
Header: line name, supervisor, quality checker, date of last change.
Columns: the operations on this line. Stitching example (shirt): collar run, collar top-stitch, placket, yoke attach, cuff, sleeve set, side seam, bottom hem, buttonhole, button sew, bartack, thread trim, final audit.
Rows: operator name, token number, months on the line, current pay band.
Rating 0: never shown the operation.
Rating 1: learning beside a buddy, bundle count and finish below target.
Rating 2: runs alone at target; the checker still finds an odd skipped stitch or puckered seam.
Rating 3: runs alone at target and quality, changes needle and presser foot, clears a jammed bobbin case, adjusts thread tension.
Rating 4: can train a newcomer and judge a colleague's bundle against the sample garment.
Bottom row: hands at rating 2 or higher per operation. A count of one is a lone dependency.
Right column: number of operations at rating 3 or above, to spot floater candidates.
Footer: supervisor signature, checker signature, plant head review date.For a rapier loom shed, the columns become beam gaiting, drawing-in, knotting, heald repair, reed denting, dobby chain reading, weft package loading, selvedge fault correction, pick finding, loom timing and cloth inspection. For a ring spinning department, use creel loading, doffing, piecing, traveller change, top roller cot check, ring rail lifting, auto-doffer faults and bobbin transport.
Filling it without arguments
- 1
Fix the rating words at a shift meeting
Read out the five lines. If two supervisors read rating 3 differently, rewrite it until they stop disagreeing.
- 2
Mark with the operator beside you
She states what she can run, you state what you have watched. Where you differ, run a timed trial of one bundle or one beam and let the checker score it.
- 3
Hold the line on ratings 2 and 3
Speed alone earns a 2. A 3 needs the ability to set up and fix a minor fault, which many fast hands cannot do yet.
- 4
Date every change
Write the date and the trial that earned it in the margin. An undated tick is not trusted by the next supervisor.
- 5
Pin it where operators can read it
A visible grid invites correction. Hands can ask for a trial to move a cell up, which turns the sheet into a path, not a verdict.
Reading the grid every month
- Single hands: list every operation whose bottom-row count is one, then name the trainee for each.
- Floater pool: pick hands with four or more operations at 3, and give them a standby allowance if your pay design allows it.
- Pay review: compare ratings against bands. A rating 4 on collar run sitting in the entry band is the person a neighbouring unit will tempt away next.
- Night and day balance: check that the second shift is not leaning on one trained hand per operation.
- Style change: when a new fabric or design arrives, add columns first, then see which operators have never touched a lycra seam or a bound edge.
Traps that spoil a good grid
- Forty columns. Merge small tasks such as tag attach and label tack into one cell.
- Marking by years served. A hand with eight years on the straight-needle machine may be a 1 on the new feed-off-the-arm machine.
- Using the sheet to blame. It shows where cover is missing, which is a planning gap before it is a person's fault.
- Leaving out support roles. Mechanics, fabric spreaders, cutters, marker makers, fusing hands and checkers deserve their own grid.
- Letting it go stale after a season change when new styles have already changed the operations list.
Who marks it, and how often
The line supervisor owns the grid and the checker confirms quality ratings. HR holds a copy and reads all grids together once a month. Update a cell the day a trial is passed or a hand leaves. Do a full read of the whole sheet every quarter. A grid that has not changed in a quarter means either a very stable line or nobody looking.
Tie it to joining. A new operator gets a row from the first morning, starting at 0 or 1. The induction steps for the first thirty days can be built around those rows, and coating and lamination line training applies the grid to nip rollers and stenter settings.
Start with the one line that hurts most when a person is absent. Fill it in over a week, read it at the Friday huddle and fix two weak spots. Then copy it to the next line. The mill and factory people toolkit lists other aids that sit beside it.
