Four short records that show a human was there when the machine did the work: what stayed human, what was learned from the miss, where the saved time went, and who carries the consequence. When somebody asks later whether this can be trusted, the answer is not a speech. It is four receipts.
The answer, in one line
Four short records kept as work is done with machines. Hand: what stayed human, named. Head: what was learned from a miss and what changed because of it.
Definition#
Hand, Head, Hours, Heart: evidence of human judgement inside fast systems. Hand records what stayed human and who will answer for it. Head records what was learned from a miss and what changed because of it. Hours records where the time saved was reinvested. Heart records who bears the consequence, including the people, animals and places downstream who never enter the system as data.
Hand: what stayed human#
Write it down, even as a single line in a log. The hiring final call made by a named person after a second-round panel. The mask fit verified by two named engineers. The pricing decision signed off by a named director after the model disagreed.
Hand is not a claim to virtue. It is a record of custody. If something goes wrong, people know where to look for the person who will answer. If it goes right, people know where the courage sat. Both matter, and organisations tend to record neither.
Head: what you learned from the miss#
Every system will be wrong. What matters is whether the loop closes somewhere a human can see it. Capture one miss and one fix per cycle. The model over-counted a same-name subsidiary, so a registry check went into the pipeline. The prompt produced a tone that read as blame, so the instruction changed and the apology was rewritten. Triage mis-flagged repeat attenders, so a feature for prior admissions was added and tested against last quarter.
Head turns error into a changed policy instead of an anecdote. It is also the only one of the four that builds capability rather than recording it, and the reason it works is the reason set out at the after action review: reviewing the process, in writing, soon enough to be accurate.
Hours: where the time went#
If you cannot point to the investment, you did not make it. Sixty minutes released by an automated report, spent calling two clients back. Ninety minutes a week moved to rehearsing the handover that matters. Thirty minutes daily on an audit of yesterday's recommendations.
Hours proves that time is a resource being allocated rather than a puddle that throughput soaks up. It is the receipt that most organisations cannot produce, because the saved time was never reallocated to anything. It went back into volume, which is the mechanism described at usage theatre.
Heart: who bears it, including the unseen#
The first three receipts are all about the decision maker. What I kept, what I learned, where my time went. None of them records the people on the other end of the decision, and the ones furthest from the room are the ones least likely to appear in any system as data.
Heart records who carries the consequence. Named where they can be named: the customer pressured after a bereavement, the applicant whose file never reached a human, the worker whose shift pattern the optimiser rewrote. And explicitly including those who never enter the system to be counted at all, the people, animals and places downstream of a supply chain or a policy, whose harm arrives as somebody else's externality.
The test is simple and uncomfortable. Who is affected by this decision who has no way of appearing in the data it was made from? If the answer is nobody, check again. If the answer is somebody, the record says who, and whether anybody asked.
Provenance. Hand, Head and Hours are set out in SuperSkills (Kogan Page, 2026), chapter seven. Heart was added in September 2026, after a conversation on the Solutionary Voices podcast with Zoe Weil of the Institute for Humane Education, which raised the harms a decision maker will never know about. The formulation here is Rahim Hirji's and first appears on this page. The book carries three.
What it looks like in practice#
Clinical triage. A hospital introduces a tool that flags possible pneumothorax on chest X-rays. Hand: the consultant radiologist signs each critical finding and calls the emergency physician directly for the patients most at risk. Head: after a fortnight the team notices under-detection in a specific group, updates the training cohort and publishes the miss and the fix at governance. Hours: time released by a faster first pass funds same-day multidisciplinary discussion for borderline cases, so the dividend buys depth rather than volume. Heart: the patients in the under-detected group are named as the ones who carried the cost of the miss, and the review says who told them.
Customer operations. A bank predicts who is likely to leave and drafts retention messages. Hand: a manager keeps the right to cancel any message where a life event makes retention pressure unethical. Head: the team finds the model over-pressures customers after bereavement, changes the feature set and logs the change. Hours: time saved on drafting goes into phone calls to the highest-risk customers. Heart: the record names the bereaved customers who received the earlier messages, and what was done about it.
Product design. A team uses a model to propose an onboarding flow. Hand: the designer keeps the right to block any design that nudges users into consent they would not freely give. Head: the model underestimated drop-off for neurodivergent users, so a slower path was added. Hours: time saved on wireframes funds a full afternoon of moderated testing rather than an hour. Heart: the users who would have been nudged are named as the people the blocked design would have cost, and they are in the record even though the design never shipped.
Using it as an assessment#
These four are the closest thing in this body of work to an assessment of judgement, and the reason is that they record behaviour rather than asking a person to rate themselves. A person who has been exercising judgement can produce the receipts. A person who has been approving cannot, and the gap shows up without anybody having to make an accusation.
Two numbers fall out of the record over time and neither needs a new instrument. The proportion of decisions where Hand names somebody, and the trend in Head entries: a team that stops finding misses has usually stopped looking. The team-level version of the same practice, three questions at the end of any meeting, is at the pause minute.
What this has not been shown to do#
Nothing here has been tested. No study has compared teams that keep these records against teams that do not, and the framework has not been validated as a measure of judgement, capability or anything else. Records can be performed: a Hand line can name a person who rubber-stamped, and a Head entry can describe a miss that cost nothing. The practice makes judgement legible where it exists. It does not create it, and it will not by itself catch an organisation determined to look compliant.
