A Scientific Approach to the Structural Failure of Management Promotion

1. Introduction: The Dual Nature of Behavioral Traits Behind Performance

This page presents a solution to the issue raised in “Are managers really delivering results through others?”
Specifically, it considers a shift toward scientific selection that recognizes the dual nature of behavioral traits.

In promotion decisions, visible performance naturally tends to dominate the evaluation.
However, the internal structure that produced that performance—thinking tendencies, emotional patterns, and values—has usually not been examined deeply enough.

That internal structure is exactly what forms a person’s strengths as an individual contributor. But once the person moves into a managerial role, where a different set of forces comes into play, the same structure can turn into a negative trait that distorts the organization.

For example:

A strong focus on speed → subordinates become hesitant
Perfectionism → inability to delegate
Strong assertiveness → escalation of friction
Self-blaming thinking → subordinates become dependent

This reversal of traits is precisely what can become the root cause of management mismatch.

Earlier, we addressed this issue from the perspective of “solutions for preventing misses in next-generation leader selection through structure.” This time, based on the practical limitations of the selection methods that many companies actually use in promotion decisions, we will present a solution that fills that gap.

This is where the main discussion begins.

2. The Solution: Scientific Selection Through Visualization of Behavioral Drivers

To assess management potential, most companies generally rely on two methods:

Evaluating project leader experience
Observing behavior through an assessment center

Both methods have a certain degree of validity. However, they also share the same limitation: they rely only on observable words and actions.

I have gone through the same process myself. In particular, in the first approach, a candidate was first appointed as a subleader on three projects over the course of one year. Only if the person passed that stage were they appointed as a project leader and assigned to projects designed to produce results within three to six months.

3. 2-1. The Limits of Evaluating Project Leaders

Project outcomes and feedback from team members are useful. It is also possible to improve accuracy by incorporating 360-degree evaluation. This means that candidates with clearly critical issues can often be identified.

The real problem lies in judging the borderline candidate. That is because the process inevitably runs into questions like these:

Why did this person make that judgment or decision?
Under what conditions is this person likely to make a poor judgment?
Under what kind of stress does this person’s perspective narrow?
With what type of subordinate is this person likely to be a poor fit?
Why did this person communicate in that way?

These aspects—the background behind the behavior—cannot be read from project results alone.

4. 2-2. The Limits of the Assessment Center

The same principle applies to assessment centers that rely heavily on behavioral observation.

Observers and evaluators are trained, and some are even formally certified.
Even so, they still confront questions such as:

“Why did this person make that statement?”
“Why was this person unable to act in that situation?”

Even if the candidate is asked and can explain it, there is no way to know whether that explanation truly captures the essence of what was going on.

The result varies depending on the evaluator’s expertise, experience, and depth of psychological understanding. Because it depends on evaluator quality, inconsistency is unavoidable. To reduce that inconsistency, companies need to hire outside experts, which then becomes a budget issue.

5. 2-3. Their Shared Critical Weakness

What both methods have in common is that they rely only on visible words and actions.

Yet the real cause lies in the unseen inner layer.

Why did this person choose that behavior?
Why did those words come out?
Under what conditions do these traits appear?
In what situations does this person’s performance decline?

Unless these invisible behavioral drivers are made visible, promotion decisions inevitably remain dependent on intuition, experience, and impression. That is why they cannot truly be called scientific.

6. The Conditions for Scientific Selection: Make the Behavioral Drivers, or Internal Structure, Visible and Use Them

The solution is to place both the observable behavior seen in projects or assessments and the internal structure that generates that behavior on the same table.

The internal behavioral drivers that need to be made visible are the following five:

Judgment patterns (how the person is likely to judge)
Thinking tendencies (what the person tends to prioritize and overlook)
Emotional reactions (how the person changes under pressure)
Behavioral traits (stable, repeated patterns of response)
Values (what the person protects and what the person is willing to sacrifice)

These are domains that can never be fully understood through observation alone.

Once the behavioral drivers become visible, the following become possible:

Explaining the reason something worked as a structure
Explaining why the person lost momentum in a reproducible way
Identifying the point at which a strength flips into a liability
Distinguishing between areas that can safely be entrusted and areas that should not be entrusted

In other words, the explainability of promotion decisions rises dramatically.

7. Conclusion: Consistent Selection Through Behavioral Drivers × Behavioral Observation Prevents Management Mismatch

Project evaluation and assessment centers are both useful. But on their own, they cannot reveal the “why.”

Behavior (the outer layer)
Behavioral drivers (the inner layer)

Only by working with both can you finally present, in an explainable way, why a person can be entrusted with a management role and what structural risks need to be watched if that person is promoted.

Select based not on outcomes or visible behavior alone, but on the internal structure of the individual.
Judge not by impression, but by behavioral drivers.

This is the only way to turn promotion decisions from a gamble into a reproducible and scientific management decision.
