The Performance Consultant AI: how a training request leads to a grounded decision about performance. Twelve pages.

A professional at his laptop

Gilbert, Mager and Pipe, Rummler and Brache, and the Dutch line of Arets, Overduin and Heijnen. Half a century of method, put within reach of every learning advisor.

A request is a solution in disguise

A manager comes to L&D and asks for training. The sentence sounds like a problem statement. It is a solution, chosen before anyone established what is actually stopping the result. Reaching for training before finding the cause is the most expensive habit in the field, and the Dutch literature gave it a name: the costly misunderstanding (Arets & Overduin, 2008; Arets & Heijnen, 2008).

The request is easy to act on, which is precisely the trouble. It arrives with the solution attached, a number of participants, sometimes a date. A department can process it without ever asking which result is missing, in whose work, and how anyone would see it. The programme runs, the dashboard looks healthy, and the problem sits where it sat.

What makes the habit expensive is not the invoice. It is that the request names the one cause a course can address, and that cause is rarely the one holding the result back. Meanwhile the working hours disappear, in numbers nobody put on the request.

This paper describes the alternative, which is old, well documented and until recently almost impossible to run on every request: find the cause first, then decide. And it describes what changes when every learning advisor has a performance consultant beside them at the intake, instead of one specialist for the few requests there is time for.

The request says training. The cause almost never does.

Figure 1 Illustrative figures. Direct cost per participant €300 to €500 for classroom teaching or €25 for e-learning; travel €120 to €200; working time at a loaded €40 an hour. The proportions carry the argument, not the totals.

Two things stand out the moment the numbers sit on the table. The invoice is the small number, and the large one is working time, which almost never appears on the request. And time scales without mercy. The e-learning for twenty thousand people looks cheap because it is digital; it consumes roughly 160,000 working hours.

None of this is controversial. It is arithmetic. What has changed is that the arithmetic now takes less time than reading the request it belongs to.

Most of the leverage sits around the person

Thomas Gilbert built the discipline on one observation: a person’s environment engineers performance far more than what sits inside their head (Gilbert, 1978). Knowledge, skill and motive matter, and they operate inside a work system that either makes good performance easy or quietly makes it impossible.

Four decades of quantitative work point the same way. A synthesis of meta-analyses across sixteen determinants of behaviour finds that knowledge, general skills, attitudes and beliefs have negligible effects as targets of an intervention; habits and social support have medium effects; and access, the material and logistic means that make a behaviour feasible, has the largest (Albarracín et al., 2024). A training request aims at the weakest determinant on that list.

the only box training can fill

Figure 2 The consultant looks in this order: first at the conditions around the work, which are the likeliest cause and the cheapest to repair, and only then at the person. Knowledge and skill is the single box a course can fill.

Work the case backwards

Performance is produced from left to right: people carry out tasks, tasks combine into processes, processes deliver results. A case gets analysed the other way. Start with the business result the organisation wants, then work back through the processes and the tasks to the place where performance actually leaks. Starting at the tasks, which is where the training request points, means starting at the wrong end (Rummler & Brache, 1995).

Figure 3 Performance runs from the person to the business result. The consultant reads it back, from the measured result to the cause.
  1. The result

    Stated as a measurable outcome, not as an activity. “More customer focus” is a wish. “Repeat orders at 62 percent against a needed 75” is a case.

  2. The gap

    The quantified distance between the result now and the result needed, with a value attached. Only a number tells you whether the problem is worth solving and whether it got solved.

  3. The causes

    Separated cleanly from the symptoms, drawn from more than one source, and never accepted on the strength of a confident opinion (Mager & Pipe, 1997).

None of this takes months. A good performance analysis is lean and fast, aimed at the few causes that matter rather than at an exhaustive audit. Its output is a short, evidence-based diagnosis that decides whether training is the answer at all.

Why so few functions work this way

If the case is this strong and this old, the obvious question is why almost no L&D function runs on it. Not because the method is in doubt. Because the daily pressures of the job run against it at every turn.

The field has known how to do this for decades. It has not been able to do it on every request.

No access to the real client

Between L&D and the manager who owns the problem sit intermediaries: HR business partners, competency owners, whoever handles training. The person who could describe the business priority is rarely in the room.

The confidence to challenge

Investigating a cause means questioning a manager’s own diagnosis. Many advisors have neither the mandate nor the practice for that conversation.

The conspiracy of convenience

Everyone prefers the quick answer. The manager sees action, L&D gets a clear deliverable, and nobody has to sit with the possibility that the problem is the system they run.

Slow work in a fast culture

Diagnosis is careful, evidence-led thinking inside an organisation built to answer now (Kahneman, 2011). Advisors who have the skill get worn down by the current.

None of these barriers is an argument against the method. Each one is an argument for making the method cheap enough to run on every request, which is exactly what changed.

What the Performance Consultant AI does

The tool guides a conversation, not a form. It sits beside the learning advisor at the intake and runs the same five moves every time.

  1. The request In plain language

    It starts with one field and one sentence: “a two-day sales training for all ten thousand reps, is training the fix?” No intake form, no template to fill in first.

  2. The questions back About numbers, not wishes

    The tool asks where the problem shows up in the figures, who is missing which target, and where the revenue leaks. The advisor supplies the detail the organisation already has.

  3. The data What the organisation knows

    Documents, dashboards and loose figures go in. The diagnosis rests on the organisation’s own evidence rather than on an assumption about it.

  4. The gap, quantified Cause by cause

    Current and needed results side by side, and under each one the cause, tagged by factor, by level, and by how far the evidence carries.

  5. The advice And the documents to use it

    Four versions of the same diagnosis, edited by the advisor, ready for the meeting where the decision gets made.

The method does not change. What changes is the scarcity: an analysis that took a specialist weeks now fits inside the intake conversation, on every request rather than the few there was time for.

The anatomy of a diagnosis

DIAGNOSTIC CONFIDENCE

THE GAP

sales per visit €18.40, target €21.00, worth about €2.6M a year

WHAT IS CAUSING IT

  • out-of-stocks on the top 40 linesprocess · triangulated
  • pricing errors at the registertools · substantiated
  • no feedback on visit value per storeexpectations · hypothesis

RECOMMENDED NEXT STEPS

fix replenishment and the price file first; coach three stores; no company-wide training

STILL TO CONFIRM · does the pattern hold in the four stores that already meet the target?

Figure 4 Illustrative diagnosis. The same anatomy whether the request covers fifty people or twenty thousand.

Every cause carries its confidence

Hypothesis, substantiated or triangulated. The tool marks its own uncertainty instead of hiding it behind fluent language.

It names what would settle the matter

The questions it would ask next, so that a strong diagnosis becomes a watertight one before anyone spends money.

It is advice, not a verdict

The diagnosis supports a decision that people make. It carries no guarantee of results, and the tool says so in plain words.

One conversation, four documents

The person who owns the money, the manager who owns the team and the analyst who owns the detail do not read the same document. The same diagnosis therefore comes out four ways, from one conversation, without a second analysis.

Figure 5 The same diagnosis comes out four ways, from one conversation, without a second analysis.

This is what changes the report L&D brings to the table. For years the function reported what it did: completions, participants, satisfaction. It can now report what it protected and what it made possible, in the language the board already speaks.

Performance consulting is the crossing

The Arets L&D Business Models place four ways of working on one rising line. The two on the left begin after someone else has decided that learning is the answer. The Performance Partner begins before that decision, establishes the cause and prescribes what the business needs, training or not. The Performance Consultant AI is what makes that crossing survivable on a normal working day.

Figure 7 The four models on one rising line: business impact grows with the maturity of the function, and the crossing lies between the HR-driven and the business-driven half.
  1. Order Taker

    Takes requests and delivers courses. Attendance counts as success. The cause of the problem never gets established, so the result rarely moves.

  2. Learning Specialist

    Designs excellent evidence-informed learning, and starts only once somebody else has decided that learning is the answer.

  3. Performance Partner

    Establishes the cause first and prescribes accordingly: process, tooling, guidance, or training where training is genuinely the answer. Includes 02.

  4. Value Creator

    Performance consulting and evidence-informed organisational learning, reported in the organisation’s own numbers. Includes 02 and 03.

The programme, the tool, the author

The programme

Tulser delivers performance consulting as one work, learn and implement programme for an L&D team: ten real requests from your own department, asked again; an advice per request that names what is going on, what helps and what it delivers; and one way of working the whole team uses afterwards. tulser.com

The Performance Consultant AI

The tool runs beside the intake conversation and is free to try. It replaces neither the L&D team nor the consultant: it removes the reason that used to decide the matter by default, which was never having the time for an analysis. tulser.ai
