Onboarding and probation for Wiring Harness Makers: a first month that gets boards right
New assembly workers take weeks to reach speed, and variant changes confuse the boards. A structured onboarding and probation gets people productive faster and shows early who will stay.

Share your requirementsWhy onboarding and probation matters in wiring harness makers
A new board worker is placed at a board and told to copy the neighbour. For two weeks the new operator is slow, makes routing errors on a variant they have not seen, and gets short remarks from the line leader. Some leave in the first month without telling anyone. The plant counts them only as another vacancy, and the next batch repeats the same experience.
A planned onboarding treats the first weeks as training, not production. A new worker spends a few days on a practice board, learns the drawing, the tape and sleeve standard and the crimp check, then moves to a live board with a buddy. Probation has set check points, so confirmation or extension is based on what was seen, not guessed.
How to set it up
1. Prepare the first day
Have the locker, uniform, seat and board ready, and name a buddy. Show where the toilet, canteen and first-aid box are. Small things settled on day one reduce early exits.
2. Run a practice board
Give two to three days on a practice board or a simple harness, with a trainer. Cover the drawing, routing, taping and a variant change. Test the worker with a simple harness at the end.
3. Move to a live board with a buddy
Place the worker on a board with a buddy for a week, with agreed targets rising each day. The line leader checks twice a shift and notes errors and help needed.
4. Set probation check points
Mark review points at two weeks, one month and the end of probation. At each point record output, errors, attendance and the worker's own comments. for the format.
5. Confirm or extend with a reason
Use the notes to decide. If extended, say what must improve and when it will be checked. Tell the worker the result in person, not on a notice board.
Check these first
Before changing anything, find out what is true today. Use your own records for a defined period and note gaps in the evidence. The review may take longer if records are incomplete or spread across teams.
- Count how many new joiners left within the first month in the last six months.
- Ask the last three joiners what was hardest in week one and note the answers.
- Read the probation record of the last confirmed worker and see what evidence was kept.
- Check how many days it took joiners to reach the target output for the board.

Questions owners ask
A few days is enough for routing and taping, with more time for complex variants. Let the trainer judge by what the worker can do alone, not by a fixed number of days.
Preferably a skilled board worker, not the line leader. The leader supervises, while the buddy teaches and answers small questions. Give buddies a small recognition so the role is wanted.
It checks if the worker has learned the job, attends, and fits the line. It also gives the worker feedback early. A clear review at one month saves a harder conversation at the end.
