Human-in-the-Loop Is a System Design Choice

An Approve button isn't oversight. Six frames on what a person needs before their judgment actually controls anything.

    A workflow can contain a human and still not be under human control. Oversight needs a decision still open, an owner, enough context, real alternatives, and a path that works when they say no.

    A person holds a steering wheel whose cable hangs loose, plugged into nothing. Below, a screen asks: send refunds automatically to all customers? Approve is the only option. Being present isn't the same as being in control. Oversight needs a decision still open, an owner, enough context, real alternatives, and a path that works when they say no.

    On an architecture diagram the first two look identical to the third. Only the third is oversight in any useful sense.

    Three different things: a person is present, perhaps only notified after the fact. Their approval is required, a real constraint but only on sequence. They can judge, and only this one is oversight. On an architecture diagram the three look the same.

  3. PRUNING MY POTHOSIS THE DECISION STILL OPEN?Already sent?Then it's not approval.SENTthen, laterAPPROVEapproving somethingthat already happenedapprovalnotification
    If the outcome is decided before they look, call the step what it is: monitoring, audit, or the start of a correction. All worth having. None of them is approval.
    PRUNINGMYPOTHOS.COM03 / 06

    An envelope is stamped sent. Later, a person is asked to approve something that already happened. Approval is crossed out in favour of notification. If the outcome is decided before they look, the step is monitoring, audit, or the start of a correction, not approval.

  4. PRUNING MY POTHOSWHICH HUMAN, AND WHY THEM“A human reviews it”isn't a design.Whoever's freeavailable isn'tresponsibleOwns the decisionwhose call itactually isHas the standingso their yessettles itKnows the subjector it's a delay,not a control
    A reviewer who can't evaluate what's in front of them is a delay, not a control. Name a person with the authority and the knowledge, not a component type.
    PRUNINGMYPOTHOS.COM04 / 06

    Whoever's free is crossed out: available isn't responsible. The reviewer should own the decision, have the standing so their yes settles it, and know the subject, or they are a delay rather than a control.

  5. PRUNING MY POTHOSWHAT HAPPENS WHEN THEY SAY NOWhat happenswhen they say no?approve → it shipsdecline → ?toast:“Declined.”and then nothingrevise, with the reasonstop and releaseask for evidenceescalatemanual route
    If refusing does nothing, the reviewer doesn't have a decision. They have a delay they're responsible for. At least one real non-approval path has to exist.
    PRUNINGMYPOTHOS.COM05 / 06

    Approve and it ships. Decline and then what? A toast saying Declined, followed by nothing, is crossed out. Real non-approval paths: revise with the reason, stop and release what was held, ask for evidence, escalate, or fall back to a manual route. If refusing does nothing, the reviewer has a delay, not a decision.

  6. PRUNING MY POTHOSWHAT THIS CHANGESFive questionsfor any Approvebutton.What decision stops here?Who owns it?What does the reviewer see?What else can they do?What happens on no?APPROVEbefore youtrust this
    Take an approval step you already have and ask these five things. If any answer is missing, the gate is doing less than it appears to.

    Five questions for any Approve button: what decision stops here, who owns it, what does the reviewer see, what else can they do, and what happens when they decline. If any answer is missing, the gate is doing less than it appears to.
