Task X-Ray Report

🛠 Project · Individual + peer review · ~3 days
Score the tasks in one real job, compare what you found with a published source, and finish with a one-page career brief.

🎯The Challenge

read this first

Jobs are bundles of tasks, and tools reach some tasks further than others. Your job is to X-ray one real job: list its tasks, score how far a tool reaches into each one and how far the four questions say it should, compare what you found with a published source, and write a one-page brief that says what you found, and what you don't know. The score isn't a prediction. It's a way to see where to look.

Rules of the project
  • Use your 3.2.3 notes. Your task list and the worker's answers are the evidence. If you used a job description, say so, and mark your own guesses as guesses.
  • Every score needs evidence you can name: what the worker said, what a published source says, or an honest "my guess."
  • Say what you found, not what will happen. One worker and one table can't predict a whole job's future. A pressure point is a place to look.
  • No names or private details. Use the alias. No employer, customer, patient or client details, and nothing confidential. A quote needs the worker's clear yes.
  • Name your sources and the date you looked. Published numbers change, and a projection is not a forecast.

🧰Quick Reference

the full lesson is in the Deep Dive

New in this project: the reach scale, the gap, comparing with published data, and the brief. The Deep Dive has practice labs and videos. Open each item below when you reach that step.

The reach scale (0 to 3)
  • 0 · None. No tool does any of this task.
  • 1 · A small part. A tool helps with a small piece, such as a lookup or a form field. A person does the rest.
  • 2 · A big part. A tool does a big part, and a person finishes, fixes or decides.
  • 3 · Most of it. A tool does most of it. A person mostly samples the results or handles exceptions.
  • Reach is about what a tool does or could do today, backed by evidence. Say which kind: the worker said, a published source says, or your guess.
The four questions, and the level they give
  • Routine or judgment? Routine → Mixed → Judgment
  • How costly is a mistake? Cheap to fix → Costly, can be undone → Costly, hard to undo
  • Does it depend on trust? Doesn't depend on it → Matters some → Depends on it
  • Who checks the AI's work? A person reads each result → Only a sample or complaints → No one checks
  • Add the answers: 0 for the first, 1 for the middle, 2 for the last. The total gives a level: 0–1 is level 1, 2–4 is level 2, 5–6 is level 3, 7–8 is level 4. A hard-to-undo mistake means level 2 at least. No one checking means level 3 at least.
  • The level sets the most a tool should do here: level 1 allows most of it, level 2 allows a big part, and levels 3 and 4 allow a small part.
The gap: can versus should
  • Gap = reach − the most the level allows. Above 0 is a pressure point: a tool reaches further than the four questions say it should. 0 is matched. Below 0 is room for help.
  • This is a simplified model. It shows where to look. It doesn't say what will happen, and it doesn't say anyone should add or remove a tool.
Comparing with a published source
  • Two free sources: O*NET OnLine (onetonline.org) lists tasks, technology skills and more for many occupations. The Occupational Outlook Handbook (bls.gov/ooh) describes what workers do and gives a ten-year outlook.
  • Write the occupation title exactly as the source lists it, the date you looked, and the outlook sentence exactly as written.
  • A projection counts jobs in an occupation. Your table is about tasks in one job. They measure different things, so you can say whether they seem to fit, not whether one proves the other.
The brief
  • One page. It states the job, one task where tools reach, one that stays with a person and why, the totals, what the published source says, a skill to build with a first step, and what you don't know.
  • Words like will be replaced, safe from, proves and everyone should go beyond your evidence. Say what you found.

1️⃣Set up

Day 1

Where did your information come from? Use your 3.2.3 notes. No real names, and no employer, customer, patient or client details.

2️⃣X-ray the tasks

Day 1 · 0 of 8 rows complete

One card per task. Fill in what you know, score the tool's reach with evidence, and answer the four questions. The page works out the level and the gap. Aim for 6 to 10 tasks, and use at least 5. Rows you don't start are ignored.

The four questions

3️⃣What the X-ray shows

computed from your rows

Complete at least one task row to see your results.

4️⃣Compare with a published source

Day 2

Look up the job on O*NET OnLine or in the Occupational Outlook Handbook (or name another published source). Copy the title and the outlook sentence exactly as written, and record the date you looked.

Is each of your tasks in the source?

Complete your task rows first.

See an invented example brief (7 tasks, a dental office scheduler)

Every person, office, tool and number in this example is invented, and its “published source” is invented too. It's built by the same code as yours.

CAREER BRIEF: dental office scheduler (invented)

Source: one interview with Worker A.

The job: A scheduler keeps the appointment book full and the front desk running, and handles patients, phones and forms.

Where tools reach: "Enter insurance details and flag missing forms". A tool does most of it. Evidence (the worker said): The software fills in most fields from the form photo, and Worker A checks only the ones it marks red. The four questions point to level 2 ("AI drafts, a person reviews each"), so this task is a pressure point.

What stays with a person: "Calm upset patients at the desk". The four questions point to level 4 ("A person does it"), because each case needs judgment, it depends on trust, and no one would catch a mistake. A mistake costs the patient's trust, and nobody else would catch it, so a person stays in charge.

Across 7 tasks: 1 pressure point, 3 matched, 3 with room for help. 1 of 6 reach scores above zero is a guess of my own. Pressure points in time-heavy tasks: "Enter insurance details and flag missing forms".

Published data: I checked an invented guide for "Dental Front Desk Scheduler" (accessed October 2026). Of my 7 tasks, 1 listed there, 3 listed in different words, and 3 not listed. It lists 1 task I didn't have. The source says: “Employment is projected to change little over the decade (invented example).” (2024 to 2034). My findings partly fit with this. The invented guide expects little change in the number of jobs, and my table shows one pressure point in a time-heavy task, which a count of jobs wouldn't show.

If I were starting in this field: I would build checking a tool's output against the paper form (Steer). First step: Double-check the flagged list against the paper forms once a week.

“The tool is fast, but I'm the one who catches what it misses.” (Worker A)

What I don't know: I talked to one worker at one office about seven tasks, so this may not match other offices, and one of my reach scores is only a guess. This rests on one worker, 7 tasks, and scores from a simplified model. A projection describes a whole occupation, not one workplace, and it is not a forecast.

6️⃣Peer review

Day 3 · pairs

Swap briefs with a partner. They read your brief and your table, and answer five questions about your work. Then you reply.

1. Could you film each task? (verb and object)
2. Is each reach score backed by evidence that isn't just a guess?
3. Does the brief say what the table shows without predicting the future?
4. Does it say what the published source says and what it doesn't show?
5. Are the limits honest, and is there no name or private detail?

7️⃣Checks and hand-in

computed from your work
Where the information comes from. Choose interview or job description. For an interview, say how you know the worker in a few words (such as "a family friend"). For a description, name the title, the site and the date.
An alias and the job's name. Write the job's name in plain words, an alias for the worker (such as "Worker A"), and tick the box that says there are no real names or private details in your work.
The worker agreed.
At least 5 complete task rows. Finish every row you started (task of 2 or more words, time, strand, reach, all four questions, and evidence for any reach above 0). You have 0 complete and 0 unfinished.
Every task passes the camera test. A task is a verb and an object you could film. Shorten any task over 12 words, and split it if it's really two.
At least one time-heavy task. Mark at least one task as taking most of the week. It's where the biggest changes would matter most.
Evidence matches the source.
The published source is named and each task is compared. Choose the source (name it if it's another one), write the occupation title exactly as it appears, enter the date you looked, and mark every task as listed, listed in different words, or not listed.
What the source says about the outlook. Copy the outlook sentence exactly as the source writes it (6 words or more) and the two years it covers.
Fit, and the reason. Choose how your findings fit with the outlook and give a reason in 8 words or more.
The job in one line. 6 words or more. What does a worker in this job do?
Two featured tasks.
A skill to build and a first step. Pick a strand, name one skill (2 words or more), and a first step within your reach (6 words or more).
What you don't know. 15 words or more. What can one worker, a handful of tasks, and a simplified model not tell you?
The brief fits one page (420 words or fewer).
No contact details anywhere.
A quote only with permission.
A peer review and your reply. Your partner answers all five, writes a comment (6 words or more), and if any answer is no, you reply (6 words or more) saying what you changed or why not.

Hand in your Task X-Ray Worksheet (or your table), your brief, and your peer review. The page sends nothing, and it never talks to a chatbot.
