Written SOPs capture what to do. Video captures the part writing loses: hand position, rhythm, the sound of a cut going right, where the expert's eyes go. For a small plant facing a retirement, video is also the cheapest serious capture tool available — the camera in your pocket is sufficient, and the method below needs no editing skills beyond trimming clips. This guide gives a supervisor or trainer a 5-step method that turns roughly one day of a veteran's time per job into a training asset a new hire can actually learn from. It targets the jobs your skills matrix flagged as one-deep.

KEY POINTS

Why this is worth a day per job

The labor math justifies the effort. BLS projects about 34,200 annual openings for machinists and tool and die makers through 2034 — overwhelmingly replacement demand as experienced workers retire or leave, against slightly declining total employment (source: BLS OOH — Machinists and Tool and Die Makers). Industry-wide, a Big Four consultancy and The Manufacturing Institute project up to 1.9 million manufacturing jobs could sit unfilled by 2033 (source: The Manufacturing Institute & a Big Four consultancy, 2024). If replacements are scarce, the leverage move is making the replacements you can get productive faster — which is precisely what indexed video of your best practitioner does. One day of veteran time per critical job is cheap against a multi-month ramp-up gap; our costing guide shows how to put your own numbers on that comparison.

The 5 steps

1 Pick & scope the job from the skills matrix 2 Pass 1: film the hands real job, no acting 3 Pass 2: why-interview veteran narrates footage 4 Cut into chapters 2-min clips + index sheet 5 Verify with a trainee done = job performed to standard
Figure: The 5-step video SOP method. Pass 2 (the why-interview) is where tacit knowledge becomes explicit.Source: Gemba Works editorial team; two-pass structure per the externalization stage of the SECI model (Nonaka & Takeuchi).
  1. Pick and scope the job. Take a one-deep job from the skills matrix. Scope it to one setup or one operation — "everything Joe knows" is not a scope; "first-article setup on the Mazak for thin-wall aluminum" is.
  2. Pass 1 — film the hands. Real production job, no rehearsal. One person films (phone, landscape, close on hands and workpiece); the veteran works normally and narrates only if it comes naturally. If the job includes safety-critical steps — lockout, guarding checks — film them explicitly and in full; a video SOP that skips them teaches the wrong lesson (OSHA requires training to be understandable to workers; see osha.gov for your obligations).
  3. Pass 2 — the why-interview. Same day or next: sit the veteran in front of the footage with the question list below, and record that conversation. Every pause, every unexplained adjustment is a question site. This pass regularly doubles the useful content — it is the step almost everyone skips, and the reason most shop videos teach motions but not judgment (the "externalization" stage described in our tacit-knowledge guide).
  4. Cut into chapters. Trim into clips of roughly 1–3 minutes, one step each, named plainly ("03 — indicating the part," "07 — what chatter sounds like"). Add a one-page index with links/QR codes and the tolerances that pass 2 surfaced. Store where production can reach it, with a named owner for updates.
  5. Verify with a trainee. A learner performs the job using only the chapters plus normal supervision. Where they stumble, the video is missing something: film the gap, re-cut, retest. Done means demonstrated.

The why-interview question list

Ask at every decision point in the footage

Use a curious junior as interviewer, not a manager — the veteran explains more to someone who genuinely doesn't know, and OSHA's worker-participation guidance points at the same dynamic: front-line knowledge surfaces in settings where sharing it is safe and valued (source: OSHA — Worker Participation).
