# Work instruction

Major steps, each with a key point for how to do it right and the reason it matters — the classic job-instruction shape, so a routing rule or a new process actually works the same way no matter who's running it.

## What it is

A work instruction is the classic three-column job instruction: major steps, key points (how to do each step right — a technique, a quality check, a safety point), and the reason each key point matters. Describe the task roughly, and real steps get drafted — grounded, specific, never a step with an unexplained rule attached to it.

## When to use it

Use it when:

- A task needs to work the same way regardless of who's doing it — a new hire, a fill-in, or the usual owner.
- A change (a new routing rule, a new process) only works if everyone actually knows the specific technique behind it, not just the headline step.
- You want to see honestly which steps still have no real key point — meaning they're not yet ready to train someone on.

Not when:

- The task is genuinely simple enough that every step is self-explanatory — forcing key points onto a trivial task adds noise, not clarity.
- You're still figuring out the process itself — map it first (a Makigami or a SIPOC), then write the instruction once it's settled.
- The 'key point' would just restate the step — a real key point adds a technique or judgement call the step alone doesn't convey.

## How to fill it in

- **purpose** — What does this task accomplish and why does it matter?
- **steps** — Drafted from your task description — major steps, each with zero or more key points and, for every key point, the reason it matters. A step with no key point yet is flagged, not hidden.
- **narrative** — Drafted from the steps actually built.

## What good looks like

The example below instructs the exact triage task the kaizen event charter's routing rule and the sustainment audit both reference — three of four steps have a real key point and reason, and the fourth is honestly left flagged rather than padded with a made-up one.

## Common mistakes

- **Writing a key point with no reason attached.** — An unexplained rule is just something to memorize — under pressure, people revert to what makes sense to them unless they understand why the rule exists.
- **Forcing a key point onto every step even when a step is genuinely simple.** — Padding a simple step with an invented key point buries the steps that actually need careful technique under noise that doesn't.
- **Writing steps that are really just a restated process map, not actions a person performs.** — A work instruction trains someone to do the task — a step must be something to actually do, not a category or a phase name.

## What it connects to

Upstream:

- **Kaizen event charter** (`kaizen-charter`) — A new process or routing rule set up by a kaizen event often needs a work instruction to actually stick once the event team moves on.

Downstream:

- **Training matrix with I, L, U, O skill levels (ILUO)** (`iluo-training-matrix`) — Once a work instruction exists, the ILUO matrix tracks who's actually been trained on it.

## Where AI helps

Judgement — stays with you:

- Deciding whether a step genuinely needs a key point or is simple enough not to
- Deciding whether a drafted key point reflects real technique or is worth sharpening

Analysis — AI helps:

- Drafting major steps, key points, and reasons from a rough task description
- Drafting the narrative from the steps actually built

Drudgery — automated:

- Counting steps and key points
- Identifying which steps still have no key point
- Exporting to xlsx in the house format

## Using this skill

Apply this method as part of whatever broader task, instructions, or deliverable you're already working on -- it's a method to use, not a standalone conversation to start. There is no generation tool for this catalogue yet, so draft the artifact's actual content yourself, following the fields above, the same way a person filling this out by hand would. The canonical guide page and a downloadable worked example (.xlsx) are at https://www.katafacts.com/katas/work-instruction.
