ROI【🔒CLASSIFIED FILE】 No. X035 | What is 6D-MATRIX

Detective Memo: The truth behind ROI Detective Agency's revolutionary problem discovery system "6D-MATRIX (6-Dimensional Matrix)." While many salespeople insist "no problems" or "everything's going well," why does this method expose hidden issues with 100% accuracy? Six thinking domains that humans unconsciously avoid—past failures, present stagnation, future anxieties—systematically scanned through Why, How, What question axes, creating a fortune-teller-like infallible system. Yet decisively different from fortune-telling is its ability to provide scientific solutions to discovered problems. Six traps that exploit the human instinct of "avoiding problems by not thinking about them" and force thinking induction. Uncover the true identity of this ultimate weapon in modern sales techniques.

What is 6D-MATRIX - Case Overview

6D-MATRIX (6-Dimensional Matrix), formally known as the "6-Dimensional Problem Discovery Framework," is an original problem identification theory extracted and systematized by ROI Detective Agency from field sales activities. By combining the time axis of "Past, Present, Future" with the question axis of "Why, How, What" in a 3×3=9-cell matrix, it forcibly visualizes thinking domains that humans unconsciously avoid and discovers problems with 100% accuracy, recognized among clients as such. However, many people understand it merely as "systematized question lists," missing the true strategic value as a psychological problem discovery system that exploits human cognitive bias and problem-avoidance psychology.

Investigation Memo: Why are problems always found in people who claim "no problems"? The answer lies in human instinct to "avoid problems by not thinking about them." 6D-MATRIX intentionally neutralizes this avoidance behavior and forcibly guides thinking into six domains. This groundbreaking approach applies the universally applicable phenomenon called "fortune-teller's trick" to scientific problem-solving.

Investigation Finding 2: 6D-MATRIX Question Design Techniques

Principles for effective question creation:

1. Ensuring unavoidable responses:
・Structure that can't be answered with "nothing particular"
・Preparation of follow-up questions seeking specific examples
・Safety question "if you had to say something?"

2. Designing gradual deep-diving:
・Surface answer → "For example?" "Specifically?"
・General answer → "In your case?" "Actually?"
・Encouraging specific recall of past experiences

3. Ensuring psychological safety:
・Eliminating critical, evaluative tone
・Emphasizing "current understanding" not "finding correct answers"
・Welcoming attitude toward sharing failures and problems

Question example variations:

Cell 1 (Past × Why):
Basic: "For past failures, why do you think they happened?"
Applied: "When things didn't work before, what was the cause in retrospect?"
Deep-dive: "Was that cause something you could control?"

Cell 4 (Present × Why):
Basic: "Why aren't you 100% satisfied with the current situation?"
Applied: "If there's something missing in current results, why do you think so?"
Deep-dive: "When did you start feeling this way?"

Cell 7 (Future × Why):
Basic: "If you continue as is, why do you think there might be risks?"
Applied: "When thinking about the future, what's the reason for your concerns?"
Deep-dive: "When do you think these concerns might become reality?"

Power of 6D-MATRIX - Hidden Truths

Warning File 1: Psychological basis for 100% problem discovery rate Humans inevitably have past failures, present dissatisfactions, and future anxieties, but usually consciously avoid them. 6D-MATRIX approaches these avoidance areas from nine different angles, creating a structure where some problems are inevitably discovered.

Warning File 2: Simultaneous understanding of problem root causes and priorities The time axis clarifies causal relationships of problems, while the question axis identifies specific improvement approaches. Beyond mere problem discovery, solution directions and priorities are naturally organized.

Warning File 3: Self-awareness promotion creating voluntary improvement motivation Rather than external pointing out, individuals "discover" problems through 6D thinking themselves, creating improvement motivation without feeling imposed upon. Change efforts begin without resistance.

Warning File 4: Organizational acquisition of continuous problem discovery capability By mastering 6D-MATRIX thinking, not just one-time problem solving but continuous ability to discover and address new problems becomes established in individuals and organizations. Sustainable improvement culture is naturally formed.

Limitations and Precautions of 6D-MATRIX - Potential Dangers

Warning File 1: Analysis paralysis risk from excessive diagnosis The most dangerous side effect. Discovering problems in all 9 cells can create an impression of being "full of problems," leading to confusion about where to start. Appropriate prioritization and phased improvement are essential.

Warning File 2: Risk of increased psychological burden and stress Forcibly surfacing problem areas usually consciously avoided may cause excessive psychological burden, anxiety, and stress to diagnosis subjects. Post-diagnosis support and follow-up are important.

Warning File 3: Hindering fundamental solutions through superficial problem discovery When questioning skills are immature, only surface problems may be discovered, missing true root causes. Continuous improvement of deep-diving techniques and insight is necessary.

Warning File 4: Risk of diagnostic bias and subjective contamination The 6D-MATRIX practitioner's preconceptions, expectations, and biases may influence diagnosis results, hindering objective problem discovery. Neutral stance and multi-perspective verification are important.

Warning File 5: Risk of privacy invasion and trust relationship breakdown Deeply exploring personal failures, anxieties, and problems may invade privacy or damage trust relationships. Appropriate boundary setting and trust building are prerequisites.

Conclusion - Investigation Summary

Final Investigation Report:

6D-MATRIX is a "revolutionary problem discovery system that exploits human problem-avoidance psychology." This original theory extracted and systematized by ROI Detective Agency from field experience breaks through the limitations of conventional problem discovery methods and functions as a powerful framework that exposes hidden problems with 100% accuracy.

The most impressive finding in this investigation was the ingenious design that neutralizes the instinctive human behavior pattern of "avoiding problems by not thinking about them" through systematic thinking induction. The 9-cell matrix combining the time axis of past, present, future with the question axis of why, how, what forcibly illuminates thinking domains that humans tend to consciously avoid, surfacing normally hidden problems.

The scientific application of the universally applicable phenomenon called "fortune-teller's trick" was also an important discovery. While having a question structure that applies to everyone, the psychological mechanism where subjects feel "this applies only to me" was ingeniously repurposed for the constructive goal of problem-solving.

The three-dimensional thinking through the two-dimensional structure of time axis and question axis was also confirmed as a remarkable feature. The design that comprehensively grasps causal relationships, chronological changes, and multi-faceted aspects of problems from nine different perspectives—often overlooked in single questions or one-dimensional analyses—is excellent.

The proven effectiveness in sales settings was also recognized as important value. The case of actually discovering nine problem areas from a salesperson who claimed "everything's going well" and "no particular problems" clearly demonstrates the method's practicality and effectiveness. The point that not only theory but field reproducibility is secured is powerful.

Integration possibilities with other business frameworks were also confirmed. Deep-diving with 5 Whys, current situation analysis with SWOT, reflection with KPT—6D-MATRIX functions as an integration platform that significantly enhances the effectiveness of existing methods.

However, the risk of analysis paralysis from excessive diagnosis also emerged as an important limitation. Discovering nine problems at once can give subjects the impression of being "full of problems," creating a danger of losing motivation for improvement. Appropriate prioritization and support system construction are key to success.

Consideration for psychological burden and stress increase was also confirmed as a necessary precaution. As a method that forcibly surfaces problem areas usually consciously avoided, constant consideration of the impact on subjects' mental health is important, with professional support provided when necessary.

Dependence on diagnostician skills was also recognized as a challenge to overcome. Since diagnosis result quality is greatly affected by questioning techniques, deep-diving ability, and insight, systematic training programs and certification system construction are essential for method proliferation and quality assurance.

Possibilities for efficiency improvement through digitalization and systematization were also confirmed. AI-powered automatic question generation, statistical analysis of diagnosis results, and accumulation of continuous improvement data have the potential to dramatically expand 6D-MATRIX's accuracy, efficiency, and application scope.

The most important discovery is that 6D-MATRIX functions beyond a mere "problem discovery tool" as a "thinking transformation system." Through continuous 6D thinking mastery, fundamental mindset transformation from problem avoidance to problem discovery is realized, fostering sustainable improvement culture at individual, organizational, and social levels.

In sales workshop applications, it becomes a powerful tool for instantly discovering participants' problems and efficiently gaining interest and trust from potential sales partners through individually optimized value propositions. It would significantly contribute to establishing a position as "a specialist who consistently supports from problem discovery to solution."

Problem Discovery Maxim: "Those who say there are no problems are the ones with the most problems. The technology to discover them is true expertise."
