Skill sits in a few pairs of hands: a fix for electrical makers

A distribution transformer sits on the test stand with three people huddled round the meter. One reading looks odd. Someone phones the chief tester, who is at a cousin's wedding two states away. The unit waits. Upstairs in the winding hall there is a separate worry. Only one man brazes tap leads on the larger ratings, and this is his fourth late night running.

It is the first pattern listed for makers of panels, transformers, motors and cables. A few people hold the quality of the whole works. Everybody knows their names. Few owners have planned for the morning one of them does not turn up.

• The planner quietly reshuffles jobs around one person's leave.
• The test stand backs up whenever a certain tester is away, though others share his designation.
• Juniors halt at the tricky step, such as reshaping an end-turn, brazing a lead or tracing a crossed ferrule, and wait.
• Customers request a particular fitter by name for commissioning.
• One senior tops the overtime ledger month after month.
• Rework tags multiply in the weeks that senior is on site or unwell.

The loss is scattered across small delays, so it seldom appears as one figure. Units idle on the stand. Coils are stripped and rewound because a junior guessed the pull on the conductor. A panel reaches site with a slip the senior would have caught in seconds.

Then comes the pay talk. A man who knows the works cannot cope without him asks for more, and the owner agrees outside any structure. Everyone else on that grade notices. The heaviest blow lands on the day he resigns, when a rival gains your drawings, your customers and your shortcuts in one hire.

• The craft was never split into pieces. Winding or testing is treated as one lump, so nobody can learn it a slice at a time.
• Teaching dents the senior's tally. A winder judged on coils per week loses count for every hour beside a helper.
• Nothing is photographed or carded. How to hold the pull, the order of tests and the buzz that means a slack clamp live in one memory.
• Holding the knack feels like protection. Near retirement, sharing can feel like coaching a replacement.
• Learners are shuffled at random. A helper who spends a month beside the senior and is then moved to packing keeps almost nothing.

• Ask each senior to write down the five tasks nobody else can do, ask their supervisor the same, then compare the two lists.
• Pull the last quarter's test holds and note who released each one.
• Read the overtime ledger and circle the names that never leave the top.
• Ask the planner which jobs move when a particular person is absent.
• Ask juniors which step they always hand back.

Where the two lists disagree, believe the supervisor's. Seniors tend to underrate how much of the plant leans on their quiet fixes.

1. 1

   Draw up a single-hand list

   For each bay, write every task that only one person can perform on a shift. This page is the plant's true risk register, and it moves the discussion from personalities to tasks.

2. 2

   Slice each task into teachable pieces

   Tap-lead brazing, for instance, becomes cleaning, fit-up, flame control and inspection. A junior can be signed off on the first two long before the last.

3. 3

   Pair one learner with each senior

   Choose someone who already asks questions and seems likely to stay. Agree the pairing with the senior directly rather than announcing it over his head.

4. 4

   Capture the method while the learner learns

   The learner photographs each stage on a phone and drafts a short card. The senior corrects it. A card clipped at the winding table beats a binder in a cupboard.

5. 5

   Let a second person sign off

   The works manager or quality lead watches the learner perform the piece alone and signs. The senior's nod alone does not count.

6. 6

   Credit the senior for every learner

   Each signed-off learner counts in the senior's review and grade, so teaching becomes part of the job instead of a favour.

7. 7

   Revisit the list each quarter

   A task drops off once two people per shift can do it. New ratings, new products and new test sets add tasks back.

Plants drift back when a fat order lands and pairing is the first casualty. Guard a small slot of paired work every week, even mid-rush. Whenever a new rating or test set arrives, name a learner for it. Planning for successors treats each name on the single-hand list as a seat needing cover. The transformer works page and its staged ladder for winders apply the same idea where one unit takes weeks to build. The owner's short version sits in protecting what senior winders and wirers know.
