When your most experienced person retires: succession planning for industrial machinery makers

The chief inspector at a lathe builder has signed off every machine's geometry for longer than most of the shop has worked there. He retires in March. He knows which bed castings move after rough machining, how long a column should rest before final scraping, and which customer will check tailstock alignment the day it arrives. Nobody else signs geometry. His retirement date has sat in the personnel file since the day he joined.

Across builders of machinery and equipment, key engineers and fitters who cannot be bought off the market come up again and again. Resignations arrive without warning. Retirements do not, which makes an unplanned one harder to excuse.

• The date is known, but nobody turns it into a plan until the farewell is being arranged.
• A successor gets named in the last month, with no time left to overlap.
• The senior is unsure whether teaching a replacement means being nudged out early.
• Nobody budgets for two people doing one job during the overlap.
• Much of what the senior knows is feel: the sound of a gearbox under load, the drag of a scraped slide, the colour of a weld.
• Customers trust the person, not the firm, and nobody has introduced the next face.

• Anyone who signs off quality. Geometry inspectors with a test mandrel and dial on machine tools, test bench leads on pumps and compressors, proof-load supervisors on cranes.
• Trades that take years. Hand scraping, spindle assembly, belt vulcanising, thin-sheet TIG work.
• Holders of customer trust. Senior service engineers and application engineers whom customers ring by name.
• The founder's first designer. Frequently the sole keeper of why the oldest models look the way they do.
• The works manager who carries the plan in his head. Loading, vendor quirks and which fitter suits which job.

1. 1

   List retirements three years out

   Pull dates of birth and retirement terms from records. Mark everyone due within three years, and flag the critical roles from the list above.

2. 2

   Map what each person holds

   Sit with them for a knowledge interview. Cover skills, judgement calls, documents only they keep, and the customers and vendors who call them directly.

3. 3

   Name two successors where you can

   One who could step in soonest, and one longer-term. Tell both, and tell the retiring person who they are.

4. 4

   Overlap on real work

   The successor works beside the senior on live machines, not in a classroom. Teaching hours go on the schedule as load.

5. 5

   Hand over sign-offs in stages

   Stage one: the successor checks, the senior signs. Stage two: the successor signs, the senior countersigns. Stage three: the successor signs alone, with the senior on call.

6. 6

   Write the trouble book together

   Each recurring problem and its cure, dictated by the senior and written by the successor. A casting that moves, a headstock that runs hot until the third hour, a customer who measures twice, a vendor whose bearings run warm.

7. 7

   Introduce the successor outside the gate

   Joint visits to key customers and vendors, with the senior saying plainly who will handle them next.

8. 8

   Agree any role after retirement

   A few seniors enjoy advising for a season. If you want that, put the scope, the days per month and a closing date on paper well ahead of the last working day.

Name, role and retirement date.
What this person signs off, and who countersigns today.
Skills that take years, listed by machine or model.
Judgement calls only this person makes, in their own words.
Documents, notebooks and files only this person keeps.
Customers and vendors who contact this person directly.
Successor soonest, and successor longer-term.
Overlap start date, and stage of sign-off reached.
Trouble book started, and pages completed.
Advisory role after retirement: yes or no, scope and end date.

Open the subject early, privately and with respect. The message is not that you are replacing them. It is that their work should outlast their time here, and that only they can pass it on. Write teaching into their duties for the final two years, and say so in their review. Recognise it at the Monday shop meeting. Seniors who feel valued teach generously. Seniors who feel pushed teach slowly.

Review the retirement list once a year, beside the skill matrix. Add any role where a resignation would hurt as much as a retirement. Machine tool builders face the longest learning curves, as keeping hand scrapers and spindle fitters explains. Pump makers rely on test bench veterans, whose retention and attrition notes cover what keeps them. For a structured approach across every critical role, see succession planning.
