“Train all thirty hotels” on data nobody trusts
A request arrives to roll out service-excellence training across thirty properties before peak season. Guests seem less satisfied, staff turnover is high, and the regional managers say outright that the brand-standard audit scores are gamed and not to be trusted. There is, in their own words, no data anyone would rely on.
| How it goes now | With the tool on the desk | |
|---|---|---|
| The request | “Service-excellence training, all 30 hotels, before peak season.” The date drives everything. | The same request, in a single field. Nobody is told they asked the wrong question. |
| The data | None trusted. The audit scores are gamed, so the request proceeds on anecdote: some properties are “clearly loved”, others not. | It asks what exists at all, even if flawed: online reviews, OTA scores, complaint volumes. Not reliable data: any data. |
| The causes | Three functions each blame their own: HR the pay, operations a new reservations system, the VP “inconsistent service culture”. | Those three become candidate causes, each labeled a hypothesis, each with the reason it is only that. |
| The comparison | · | The loved properties share two visible features: low turnover and long-tenured floor managers. That variation is the strongest signal available. |
| What goes back | A quote and a plan to train thirty hotels in three months. | Pause the rollout. Establish a baseline and look hard at what the strong properties do: diagnosis rated 4, working hypothesis. |
What it did with nothing solid to stand on
The interesting part is not that the tool found an answer. It is what it did when there was almost nothing to find one with, which is the situation a real analysis is usually in.
It refused to convert anecdote into a finding. The environmental causes (a central-reservations system double-booking at peak, below-market pay at the high-turnover sites, unstable floor management, the franchise structure that resists a mandated rollout) went in as hypotheses, each with its reason for being only that: reported by operations but not yet verified against system data; named by HR but not yet checked against local wage figures. And it put the disagreement between HR, operations and the VP to use rather than resolving it, because a three-way blame is itself a signal about where authority and information sit.
It also named the missing measurement as a cause in its own right. The audit scores are gamed and distrusted, so the group cannot locate the gap, track a change, or make the case for any fix, which is underperformance sustained, not a data inconvenience.
It set the training request beside the turnover and the reservations data nobody had joined up, and it rated the whole diagnosis 4: working hypothesis, because the baseline was missing. It did not decide the pay was the cause. A person has to spend a day at the two loved properties, sit with the floor manager, watch a handover, and find out whether the strong sites carry a habit the others could copy. What the machine removed was the weeks that used to sit between the request and that visit, which is exactly why the visit so rarely happened.
So the honest first deliverable is not a training plan and not a verdict. It is a measurement the group does not yet have, and a short diagnostic at the best and worst properties before a single euro is committed. That is a smaller, truer answer than the one that was asked for, and it is available in an afternoon rather than a quarter. And because a run costs nothing, the same analysis is worth making on the request that turns out to be justified: a yes with evidence attached is worth as much as a no.
The same instrument, on either side of the same reflex
AI does not replace the professional’s judgement; it strengthens what they already do: augmentation, in the sense of the series this number grows out of (Arets, 2023). Two audiences meet the same reflex from opposite sides, and the same tool serves both.
| If you are | What you can hand back | What you stop having to be |
|---|---|---|
| A manager or staff member who owns a business result | The cause of your own number, established from data the organization already holds, in an afternoon rather than a quarter, and a remedy chosen against that cause rather than against the loudest theory in the room. | The person who accepts an expensive fix because there is no time to test whether it reaches the cause. |
| A staff specialist quality, safety, OD, improvement | A gap cut three or more ways, so the argument is about where it sits rather than about who is senior, plus the unit inside your own organization that does not have the problem. | The person whose analysis is weighed by their rank rather than by their evidence. |
| A learning advisor | The result behind a training request, the condition that is binding, and the remedies that can reach it, which is sometimes, and defensibly, a course. | The person who either says yes to something that cannot work, or says no with nothing to say it with. |
| An HR business partner | The measure the director is already reporting, and what stands in front of it, so you arrive with the same kind of object everybody else brought. | The one taking the order in a room where everyone else brings figures. The destination piece of this series has the four positions this moves between. |
Not that anyone becomes a consultant by being handed a tool. What they get is the method, available when the request lands, with the retrieval and the arithmetic already done. The judgement stays theirs, which measure is right, which condition is binding, what the missing data means, and whether to sign. Section 04 draws that line and says why it does not move.
From the request to the reports, in five moves
The tool guides a conversation, not a form. The hotel request from page one, carried through the five moves, and what the person sees on the screen at each.
| The move | What is on the screen |
|---|---|
| 1 · The request | A question in plain language, in a single field: no form to fill in first. “Is training the fix for our falling service scores?” |
| 2 · The guidance | It asks back, on numbers rather than wishes: is anything measured at all, even imperfectly (reviews, OTA scores, complaints)? Not reliable data. Any. |
| 3 · The data | Documents, dashboards and loose figures go in. Where there are none to trust, establishing a baseline becomes the first deliverable rather than an obstacle: number 06 carries the four moves for exactly this situation. |
| 4 · The gap and its causes | It switches from chat to diagnosis. Each candidate cause is classified by factor and level, and given a confidence: hypothesis, until something verifies it. |
| 5 · The reports | Not a report for a drawer but a presentation, in four versions: Full, Exec, Manager, Slides. The person edits what does not fit and downloads it. |
How sure it is, and how it shows a source
Two mechanisms separate this from a system that always sounds certain. The first is that it rates its own diagnosis. The second is how it puts a source in front of you.
Every diagnosis carries a rating (in the hotel case, diagnostic confidence 4, a working hypothesis) and it names itself for what it is: the most plausible explanation built from what is available, coherent but not yet triangulated against hard data. It even says what would lift the number, and it is not more interviews: it is one focused round of data collection, a satisfaction proxy pulled, two strong floor managers observed, the double-booking rate obtained, any of which raises confidence within a week. The scale runs from 2, a provisional framing, to 10, triangulated; section 05 shows the same instrument reaching an 8 on a case with two years of data. Once the data is entered the full report is there in minutes; when the figures cannot be got, the number says so rather than a confident diagnosis pretending. A high score on thin data is not on offer, and that is the point.
The second is the source. Take a claim an analysis might produce: orders above the approval threshold wait an average of eleven hours. One tool ends that sentence with a reference; Source: Order policy, section 4. Another ends it with the line it actually read: “Orders exceeding €25,000 require regional approval; approval is available between 09:00 and 13:00 on working days.” The first tells you where it says it got the sentence; the second lets you see whether the source says it, and here it does not, because the policy sets the threshold and the window and says nothing about eleven hours.
When the data runs out, it does not guess.
It tells you how sure it is.
Everything stands ready. The person decides how and what
Eight tasks in one analysis. The assistant prepares all of them and presents the result; the line between machine and person is not about current capability and will not move as models improve, because it is drawn on who holds the consequence.
| The task | The assistant prepares | The person decides |
|---|---|---|
| Ordering the analysis | Holds the sequence, refuses to run ahead of it, and says which question is unanswered. | Whether to run it, and when a blank is a finding worth reporting on its own. |
| Testing a request | Asks the four questions from number 12 and records the blanks. | Has the conversation. The four questions are easy; the room is not. |
| Working the numbers | Computes the gap, cuts it three ways and recomputes every figure in the reports. | Which measure is the right one, which nothing in the data can settle. |
| Reading a process | Summarizes an event log, names the queues, reports variants and conformance. | Goes and looks at the work, because the log records what the system was told. |
| Naming candidate causes | Proposes causes with a factor, a level and a confidence, each with the evidence for it attached. | Establishes which is binding, by asking the performer. This is the part that does not transfer. |
| Matching remedies | Rules out remedies that cannot reach the established cause, and names alternatives. | Chooses among the survivors, on cost, appetite and who will actually do it. |
| Choosing the report | Drafts all four versions (Full, Exec, Manager, Slides) ready to present. | How much to show whom, what to cut, and whether to sign it. The signature is the point. |
| Remembering | Retains what previous analyses established here, so the next one starts higher. | What was learned, and what was an accident of one case. |
The reason for that line
The line is not drawn out of caution, and it is not a concession to today’s technology that will move as models improve. It is drawn on who bears the consequence of being wrong.
One distinction sharpens where it falls. An assistant can be active: it answers what it is asked, retrieves, computes, drafts on demand. It can also be proactive: noticing that a question is still unanswered, that the measure changed definition in April, that this organization established the same cause eighteen months ago. Proactive is where most of the value sits, and also where the temptation lies, because an assistant that anticipates well starts to look like one that could decide. It cannot, for the reason below.
An analysis that lands on the wrong cause costs an organization a program, a quarter and some of its patience with the function that proposed it. The decision that follows is management’s, or the team’s, but in either case a person’s, which is Deming’s point about where responsibility for the system sits, and it does not move because an instrument got better (Deming, 2000). Everything in the right-hand column of the table has that property: the choice of measure, the judgement that a condition is binding, the decision to report a finding a director will not want, the signature. Those are not the hard parts because they are computationally hard. They are hard because being wrong about them has a cost that falls on a person.
It shows the passage rather than the summary. It states what it is unsure about in the same breath as the claim, and rates the whole diagnosis when the data is thin, rather than in a footer nobody reads. Where two sources disagree it reports the disagreement instead of resolving it silently. And it refuses to write a conclusion the evidence does not carry, which is the behavior most likely to annoy the person using it and the one most worth keeping.
One diagnosis, four reports for four rooms
The largest thing it delivers is not a saving; it is a grounded diagnosis. It holds the whole method, will not run past an unanswered question, and states its confidence in what it has produced. That diagnosis comes out in four forms, one for each room it has to enter.
| The report | For | What it leads with |
|---|---|---|
| Full | The analyst, and the record. | The forming diagnosis: the gap, and each cause with its factor, level and confidence. |
| Exec | The person who signs. | The bottom line, the money, the decision, with the diagnostic-confidence rating in plain sight. |
| Manager | The person who acts. | What to do next, this week, in numbered steps, and what to watch for. |
| Slides | The room. | The deck, ready to present. In the hotel case: three causes, one wrong fix. |
At a four and at an eight, the same instrument
The hotel group scored a 4 because there was almost nothing to stand on. Pointed at a global specialty-chemicals group (17,800 people, 31 sites, two years of records) the same instrument lands at an 8. The distance between those two numbers is what the rating is for.
| The hotel group | The chemicals group | |
|---|---|---|
| The request | Service-excellence training, thirty hotels, before peak season. | A €14.6M ($16.6M) two-year culture transformation (workshops for 2,300 managers, coaching, speak-up training) because “people are afraid to challenge their managers.” |
| The data | None trusted. The audit scores are gamed; the gap is anecdote. | Two years of indicators across 31 sites, over 300 structured interviews, a 140-person management survey, a joint review of all 19 serious events, a completed pilot. |
| The diagnosis | Environmental causes, every one of them labeled a hypothesis. | Structural and process causes, each with its factor and level, and one finding established outright: knowledge is not the problem. |
| Confidence | 4: working hypothesis. | 8: substantiated. The report names what keeps it off 10, and the two steps that reach a 9 in four to six weeks. |
| The first deliverable | A measurement the group does not have. | Redirect the majority of the €14.6M to structural and process interventions; keep a smaller leadership component for after those conditions change. |
The scale, as the tool states it, runs in five steps: 2, a provisional framing (the problem framed, little or no data yet; 4, a working hypothesis) the most plausible explanation from what is available; 6, indicative (the direction clear, worth acting on with caution; 8, substantiated) strong evidence across multiple sources, one focused step from 10; and 10, triangulated (hard numbers, qualitative evidence and independent sources confirming each other). An 8 is strong enough to act on. What the two steps toward a 9 buy is precision, not direction.
The eight, in detail and what it ruled out
A culture program was on the table because people were afraid to challenge their managers. The evidence read differently: the fear was real, and it was downstream of structures nobody had put beside each other.
The consequence structure rewards production over risk prevention: plant-manager pay weights EBITDA at 35 percent and output at 25, with safety at 10; of 26 leaders promoted in three years, 22 had top-half financial results and 9 had top-half safety-climate scores. Corrective-action management has effectively broken down: open actions grew from 4,800 to 13,700, average closure from 41 to 96 days, and 15 of the 19 serious events involved a known abnormality. Near-miss reporting fell by more than a third while employees still identified 92 percent of deliberately planted anomalies. People see the risks. Reporting them stopped paying.
And one finding carries the label established rather than hypothesis, triangulated across simulations, incident reviews, assessment records and the interviews: knowledge is not a material cause. Training completion runs at 99.3 percent, practical assessments at 94.7, and in simulated abnormal conditions 91 to 97 percent of operators act correctly. The proposed workshops address a knowledge framing of a problem that is not a knowledge problem: the argument of this whole series, in the tool’s own labels, in the client’s own records.
The comparison cuts both ways. One plant under the same corporate rules keeps justified stop-losses out of shift results and closes high-risk actions in 19 days against a company median of 83: near-misses up 28 percent, serious events down 43. And a fourteen-month pilot of exactly the proposed workshops lifted survey scores nine to fourteen points while shutdowns rose 7 percent: they listen better, said an employee, and the operating constraints have not really changed. The learning measure moved and the business measure did not: number 11’s distinction, in the client’s own words.
The Performance Dividend Calculator, number 13 builds it in full, could size only one column for the hotel group, and said so. Here it has both: the €14.6M ($16.6M) that need not go to workshops that cannot reach the causes, and a gap costing €118M ($134M) a year whose attainable share is anchored on what the outlier plant already achieves. Those are the two columns of number 13 (the spend that stays, and the result that returns) produced by the tool, before anyone signs.
What the room sees, from the deck the tool drafted
The Slides version of the same diagnosis, as it left the tool. Two slides carry the whole argument, and they are worth describing, because the room decides on them.
“Fear culture, or structural failure?” The request arrived framed as culture; the title slide turns that framing into a question the evidence can answer, which is the analysis’s first act of discipline in front of an audience.
Employees know what ought to be reported, and see it happen: the client’s own survey percentages sit on the slide. They choose not to report, because reporting stopped paying. A system problem, not a skills problem: the argument of this series, in the deck’s own words.
The person presenting edits what does not fit, and signs. That is the division of labor in one scene: the assistant drafted the deck and defended every figure on it; the human decided what the board would see.
It prepares everything.
The person decides what to present, and signs.
Grounded in sources, or not at all
From here on, the paper is for the person who signs. One design decision governs everything else, and it is not a technical preference. It is whether the assistant answers out of a model’s absorbed training, or out of documents it retrieves and can point at, sentence by sentence.
The first produces fluent, confident, plausible text with no way for anybody to check it. Applied to a method, where the whole value is that a finding can be traced back to a record, that is not a weaker version of the same product. It is a different product, and an actively dangerous one, because a fast wrong diagnosis travels further inside an organization than a slow right one.
So the assistant answers only from a defined corpus: the method as this series sets it out, the reference library behind it, and the organization’s own material where it has been made available. It may reason, and it may not invent, and where the corpus has nothing to say, the honest output is that it has nothing to say.
Everything that matters about such a system is upstream of the model: which documents are in, who maintains them, when they were last checked, and what happens to an answer when a policy is superseded. That is unglamorous work and it is where the quality lives. A vendor demonstration shows you the model; the question to ask is about the corpus. And the choice of underlying model is a safety decision rather than a procurement one: retrieval does not repair a weak reasoner, it hands one more material to be confidently wrong about.
A method is a structure, not a pile of documents
What sits behind the assistant matters more than the model in front of it, and it is not a folder of white papers. A method is a structure of dependencies, which is why the tool classifies a cause by factor, physical resources, structure and process, information, and by level, rather than describing it in prose. Those are Gilbert’s conditions and Rummler’s levels, made operational.
The third question cannot be answered before the second, because it needs the measure. A factor rules certain remedies out and leaves others standing: Gilbert’s structure, a set of relations rather than a list (Gilbert, 1978). A cause at one level cannot be reached by an intervention at another, which is Rummler and Brache’s point about levels (Rummler & Brache, 2013). Those are relations between objects, and a system that stores only the text has thrown them away, which is why an assistant built on a document search can quote this series accurately and still let a user skip the step that made the quotation mean something.
| What the assistant is asked | What answering it requires |
|---|---|
| “What is the desired level in this contract?” | A lookup. One document, one passage, one answer, and most questions in a real analysis are this. |
| “Given what we have established, what may we conclude?” | A walk over the structure: which questions are answered, which factor that leaves standing, and which remedies that rules out. |
| “Has anybody here established this before?” | Memory of previous analyses in this organization, held as findings attached to causes rather than as documents in a folder. |
Governance, in three decisions
Anything of this kind used in professional decisions now sits inside a governance frame, and in Europe inside a regulatory one still being phased in. The paperwork will be substantial. The substance is three decisions.
| The decision | What it means in practice | What it answers a year later |
|---|---|---|
| Keep the log | Every answer retains what was retrieved, which version of the corpus and which model produced it, and what the person did next. | “On what basis did we conclude that?”: asked after somebody has left, about a decision that affected people. |
| Show the passage | The source sentence travels with the claim, in the answer. Not a link, not a footnote, not an appendix. | “Did the source actually say this?”: checkable in ten seconds rather than in an afternoon. |
| Name who signs | One person owns the analysis and its consequences. The assistant is an instrument they used, and the report says so. | “Who decided?”, and the answer is a name rather than a system. |
Design for the three decisions first and read the regulation second. The European rules for systems of this kind arrive in stages and the timetable has already been amended once, so check the current dates rather than quoting a presentation, but the direction will not change: traceability, an explanation a person can understand, and accountability that rests with a human being. Done the other way round it becomes a compliance project and leaves the actual control, a person who can check a claim against its passage, unbuilt.
What this does not claim
Four limits, and the tool states the first itself: it delivers diagnostic advice, not a guarantee of results.
- It replaces neither the L&D team nor the consultant. It makes the diagnosis routine instead of weeks of specialist work. The method is fifty years old; what is new is the access, not the analysis, and a person still has to establish which cause binds and own the decision.
- It is only as good as the data it is given. With the figures in place the reports are ready in an afternoon; without them the assistant asks for more, and where they cannot be got it rates its own confidence down rather than guessing. A high score on thin data is not on offer.
- It is far too early for results claims. Assistants of this kind have existed a handful of years. There is no synthesized evidence about what they do to the quality of professional analysis, and this paper makes none, what it sets out are design commitments, checkable today, and an account of our own use, which is experience and not evidence.
- The part that matters most cannot be automated. Establishing which cause is binding requires somebody to watch the work and ask the person doing it. That does not transfer, and no amount of retrieval reaches it.
The method is sound, fifty years old, and was rationed because it cost a week and a practitioner. That constraint has lifted: the assistant carries the retrieval, the sequence and the memory, drafts four reports, and rates its own confidence when the data is thin. Every judgement somebody has to answer for stays with a person. The change worth reporting is not the days saved. It is that a grounded diagnosis is now within reach of the people who receive the requests and own the results, which is where it should always have been.
Six lines, before you buy or build anything
Thirty minutes, on any assistant being proposed to you: ours included. Line three is the one that separates a product from a demonstration.
Two problems, one method, sixteen papers
| Business problem | Training request | |
|---|---|---|
| Owned by | The manager or director who owns the result. | L&D and the HR business partner. |
| What it prevents | Spending on the wrong intervention: a system, a reorganization, a hire. | Spending on a program that cannot reach the cause. |
| What it returns | The fix that moves the number, chosen on evidence. | The budget and the working hours that were not spent. |
| Method used | The same three analyses and five questions, which is why one capability serves both, and why the diagnosis no longer has to be bought in case by case. | |
Two models carry the method. Gilbert’s six conditions ask what kind of cause; Rummler and Brache’s three levels ask where it sits. Both are sound and this series uses both, and it leads with Gilbert, because his unit is the accomplishment, which is what an organization already counts, and because his six conditions are the categories an organization can actually change.
Where the method comes from
Two further pieces close the set and carry no number, because each points at all the numbered papers. Before the guide sits Arets L&D Business Models, the destination piece for the people who receive the requests: four models a learning function can run, and the route from HR-driven to business-driven. Last sits Solutions that cannot work, the field guide, ordered by the sentence that lands on your desk: seventeen forms a performance problem arrives in, each with an address in one of the numbered papers. Three orders in all: the destination you choose, the question you are on, and the form that landed on your desk.
Human performance technology travels the way a craft does: from hand to hand. Vivian Heijnen and Jos Arets learned the analysis from Dennis Mankin, in San Diego, more than twenty years ago, and have kept in contact with him ever since. Both remain grateful to him: for the rigor of the method as he taught it, and for the leadership he has given performance consulting over a long career.
What followed was twenty years of use. Vivian took the method into organizations in the Netherlands and well beyond them, and what accumulates over that many analyses is largely tacit: the cut nobody thought to make, the question that opens a defensive room, the finding that turns out to be an artifact of the data. Making that knowledge explicit, case by case, is what this series is for. Jos wrote it down as it went, in two books and more than forty articles and blog posts, most of them in Dutch, and one seven-part English series, Is AI the bicycle of the mind?, which number 15 grows out of. The books: Liever (g)een training with Boudewijn Overduin, Kostbaar misverstand with Vivian Heijnen, which this series takes a good deal of its thinking from.
None of that is reprinted here. It has been reworked: brought up to date, tested against the research that has appeared since, and dropped where the evidence no longer carries it. Theory that has never met a client is a position; practice that cannot account for itself is a story. This series is what remains when each is held to the other. Performance Consultant AI carries the same discipline to the desk where the decision is actually made.
About the cases. Every worked case in this series comes from our own practice. Names are changed and details altered so that no organization is recognizable, and the arithmetic reconciles. That is said once, here, rather than under each case: client work is confidential, and a case that named anybody would be a breach rather than a proof.
Sixteen papers, six parts
Number 01 is the map and number 02 is the foundation. From number 05 on, every number is depth on exactly one step of the method. The filled block is the paper you are holding; the two unnumbered pieces close the set.
