20 years of judgment. Ten weeks to capture it.

Ray Delgado is retiring. He is the only one who can nurse Plant 2’s Line 3 palletizer through a bad night, and almost none of what he knows is written down. Here is how a capture runs, across four interviews.

The situation

The go-to person is walking out the door

Meridian Packaging, Plant 2. Ray has run maintenance on the folding-carton lines for two decades. When something breaks that no one else understands, the call is always the same: "get Ray." In ten weeks that stops being an option.

What they own

  • Line 3Robotic palletizer - a Fanuc arm on a legacy Allen-Bradley PLC; the plant’s most fragile asset.
  • Boiler rmTwo firetube boilers feeding process steam and the glue heaters.
  • Line 1-2Folder-gluer and rotary die-cutter setup, changeovers, and web-tension calls.
  • UtilitiesCompressed air and facilities HVAC - two rotary-screw compressors and the plant chillers.

What the manager is afraid of

“If the Line 3 palletizer goes down at 2 a.m., Ray is the only one who can bring it back. Marcus is sharp, but he has never run the annual boiler shutdown, and half of what Ray does isn’t in any manual.”

Successor: Marcus Bell, three years on the floor. Capable, but he has been shadowing, not leading.

Phase 01 · Set up

Before a single question, the system maps the risk

It reads the role and the manager’s intake and predicts where the tacit knowledge concentrates, so the first interview walks in aimed, not cold.

Predicted high-risk tacit areas

  • CriticalLine 3 palletizer fault recovery - concentrated in one person, no runbook.
  • CriticalBoiler cold-start and annual shutdown - calendar-driven, rarely performed.
  • HighVendor and spare-parts relationships - who to call, what actually ships.
  • HighDie-cutter setup judgment - deviations from OEM spec.

A probe it generated for session 1

“Walk me through a normal week. When something breaks that only you can fix, what is it usually, and what do you do that you have never written down?”

Phase 02 · Capture

4 interviews, 4 layers

Each session has a different job. After every one, the transcript is analyzed and coverage is re-scored, so the number climbs as the tacit knowledge comes out.

Facilitator

When something breaks that only you can fix, what is it usually?

Ray

Nine times out of ten it’s the Line 3 palletizer. If she faults on a heavy pallet, everyone stands around until I get there. I clear the jam in manual, jog the arm off the stack, then re-home it - but you have to do it in the right order or you trip the cell and lose another twenty minutes.

Facilitator

Is that sequence written down anywhere?

Ray

No. It’s just in my hands at this point.

Walk me through the last time Line 3 went down for real.

Ray

It chattered on startup. A young guy hears chatter and swaps the drive - wrong. If it chatters cold and clears once it’s warm, that’s the #4 idler bearing, not the VFD. I watch the amp draw; if it’s pulling high before the belt even loads, it’s mechanical. Swapping a $2,000 drive won’t fix a $60 bearing.

Ray

And the accel - the OEM value trips her on a full pallet. Years ago I dialed it down about fifteen percent. Nobody knows that. If someone "restores defaults," she’ll fault every heavy cycle and they’ll chase it for a week.

Knowledge captured

  • Startup-chatter diagnosisDecision
  • Amp draw as bearing-wear tellDecision
  • SRVO fault triageDecision

Tacit knowledge surfaced

Distinguishes a worn idler bearing from a drive fault by cold-vs-warm chatter and pre-load amp draw - before any vibration data.

Reduced palletizer acceleration ~15% below OEM spec to stop nuisance trips. Undocumented deviation.

Facilitator

When you need a part fast, what do you actually do?

Ray

Don’t call the 800 number, you’ll wait three days. Call Dave at Reliance direct - he’ll overnight a drive off the record. And the palletizer bearings: the OEM number is superseded. I cross to an SKF equivalent; it’s better and half the price. That cross-reference isn’t in the CMMS.

Ray

One safety thing: the lockout procedure doesn’t mention the pneumatic accumulator. Lock out electrical but don’t bleed it, and the arm can still drift. I always bleed it first.

Knowledge captured

  • Reliance rep - Dave KowalskiContact
  • Bearing OEM to SKF cross-refPart
  • Palletizer LOTO - accumulator bleedSafety

Tacit knowledge surfaced

Personal vendor relationships that bypass slow official channels; a parts cross-reference that lives only in his head.

Facilitator

The annual shutdown - what’s the order, and what goes wrong if it’s off?

Ray

Boilers first, always. Drain and cool #1 before you touch #2, or you lose steam to the glue heaters and the whole plant stops. The state inspector comes on day two, so the fireside has to be open and clean by then. I keep the sequence on a sticky note in my toolbox - that’s the "system."

Facilitator

Could Marcus run it today?

Ray

The palletizer recovery, if he shadows me twice more, yes. The shutdown - not without me standing there once.

Coverage cleared the quality bar at 79/100 with no open critical gaps. Three areas remain concentrated in Ray and are carried into the deliverables as named risks: palletizer fault recovery, the OEM-deviation values, and the annual shutdown Marcus has not yet led. Each has an owner and a next step.

Executive summary

Ray Delgado holds concentrated, largely tacit responsibility for Plant 2’s Line 3 palletizer and boiler room - systems where he has, until now, been the only person who could recover a failure. Across four capture sessions, in-scope coverage rose from 0 to 79/100, and the number of tasks with a single point of failure fell from 7 to 2. No critical gaps remain open. Two areas still depend on Ray’s hands-on judgment, and both carry a dated plan below that closes them before his departure.

01 · Critical systems & current understanding

  • Line 3 palletizer - was Ray only; now documented with Marcus shadowing. Status: watch.
  • Boiler start & shutdown - documented; one supervised run pending.
  • Die-cutter setup - partially captured; judgment-heavy.
  • PM route & utilities - written and transferable.

02 · Tacit knowledge captured

  • Chatter diagnosis: cold-vs-warm chatter plus pre-load amp draw tells a worn bearing from a drive fault - a $60 fix mistaken for a $2,000 one.
  • OEM deviation: palletizer acceleration set ~15% below default to stop nuisance trips; "restore defaults" brings the fault back.
  • Safety step: the pneumatic accumulator must be bled before lockout - a step the written LOTO omits.
  • Supply chain: a direct vendor line that ships same-day and a bearing cross-reference, neither in the CMMS.

03 · Risks & mitigations

  • High - palletizer recovery still hands-on. Marcus shadows two live recoveries. Owner: Ray, wk 3-6.
  • High - LOTO omits stored pneumatic energy. Reissue with the accumulator bleed. Owner: Safety, wk 2.
  • Med - annual shutdown never led by successor. One supervised run. Owner: Ray + Marcus, wk 8.
  • Med - OEM-deviation values only in memory. Record in CMMS. Owner: Ray, wk 2.

04 · Successor readiness - Marcus Bell

Marcus already runs the PM route and routine corrective work unaided. He is close on palletizer recovery - two shadowed sessions should close it - and not yet independent on the annual shutdown, which is calendar-bound. Recommendation: certify palletizer recovery after the second shadowed run; schedule the supervised shutdown in week 8; hold formal readiness sign-off for the plant manager, who cannot self-certify.
