The New Form of Manuals Enabled by Decision Trace Model × Multi-Agent

Introduction

Traditional manuals have been designed to tell us:

👉 What to do

However, what is truly needed in real-world operations is:

👉 How to decide

Across manufacturing, retail, and service industries,
even though manuals are well prepared, the following problems persist:

  • Decisions vary from person to person
  • Manuals are not used in practice
  • Expert knowledge is not effectively transferred

The reason is clear:

👉 Manuals deal only with information

Limitations of Traditional Manuals

Manufacturing

  • Procedures exist, but exception handling is not documented
  • Decisions during abnormalities depend on individuals

👉 Whether to stop the line depends on the person

Retail

  • Customer service manuals exist
  • But situational decisions are left to frontline staff

👉 Discounts, recommendations, and responses vary by person

Service Industry

  • Response flows are defined
  • But complaint handling and exceptions are personalized

👉 Customer experience becomes inconsistent

The Core Problem

The common issue is:

👉 Manuals capture only results and procedures

But in reality, what matters is:

  • How the situation was interpreted (Signal)
  • What reasoning was applied (Evaluation)
  • Why a particular action was chosen (Decision)

👉 The decision-making process

In other words:

👉 Results exist, but decisions do not

This is why manuals fail to function.

Solution: A New Form of Manuals

Decision Trace Model × Multi-Agent:

👉 Redefines manuals as structures of decision-making

Core Structure

Event
→ Signal
→ Evaluation
→ Decision
→ Execution
→ Human
→ Log

Traditional manuals:

👉 Describe procedures

New manuals:

👉 Reproduce decision processes

Decomposition via Multi-Agent

Expert intuition is:

👉 A combination of multiple integrated decision processes

DTM × Multi-Agent decomposes it into:

  • Signal Agent (state recognition)
  • Diagnosis Agent (cause estimation)
  • Decision Agent (action selection)
  • Policy Agent (rules and constraints)
  • Risk Agent (risk evaluation)
  • Execution Agent (execution)

👉 Intuition = a decomposable structure

Structure of the New Manual (Decision Trace-Based)

Traditional manuals:

👉 Linear documents read from top to bottom

In contrast:

👉 Decision Trace-based manuals dynamically unfold based on context

Core Components

① Event (What is happening)

  • Equipment anomalies / complaints / defects

② Signal (What is observed)

  • Sensor values
  • Logs
  • Features

③ Diagnosis / Evaluation (How it is interpreted)

  • Possible causes
  • Multiple hypotheses
  • Comparative evaluation

④ Decision (What is chosen)

  • Action candidates
  • Reasons for selection

⑤ Policy / Risk (Constraints and considerations)

  • Safety standards
  • Quality rules
  • Risk evaluation

⑥ Execution (What is done)

  • Concrete actions

⑦ Log (Everything recorded)

  • Decision history
  • Results
  • Feedback

👉 Manuals become not instructions, but
👉 frameworks for decision-making

UX: How It Is Used in Practice

This is the most critical shift.

New manuals are:

👉 Not something to read
👉 But something to interact with

① Input (Event-driven)

Operators input:

  • “Vibration is higher than usual”
  • “Temperature is rising”

👉 Or automatically captured via IoT

② AI Presents Signal / Diagnosis

The system:

  • Detects patterns
  • Suggests causes
  • Shows similar cases

👉 Provides material for thinking

③ Visualization of Decision Process

The interface shows:

  • Why a recommendation appears
  • What risks are involved
  • What rules are applied

👉 No black box

④ Decision Support

  • Recommended actions are presented
  • Alternatives are shown

👉 Humans focus on selecting

⑤ Human Boundary

  • Approve / hold / escalate

👉 Responsibility is clear

⑥ Automatic Logging

  • What decision was chosen
  • What outcome occurred

👉 All recorded automatically

UI Concept

The new manual is:

👉 Not a flowchart
👉 But a decision navigation system

Example:

Anomaly detected
↓
Cause candidates (3)
↓
Risk comparison
↓
Recommended action (+ reasoning)
↓
Human selects

👉 Dynamic, not fixed branching

UX Comparison

Traditional:

  • Search
  • Read
  • Interpret
  • Decide

New model:

  • Input
  • See options
  • Understand reasoning
  • Select

👉 Cognitive load is dramatically reduced

Use Cases

Manufacturing: Equipment Failure

Event → Signal → Diagnosis → Risk → Policy → Decision

👉 Reproducible responses

Retail: Customer Interaction

Event → Signal → Evaluation → Risk → Decision

👉 Consistent service quality

Service: Complaint Handling

Event → Signal → Diagnosis → Policy → Decision

👉 Standardized customer experience

Training

  • Decision processes are shown
  • Reasoning and branches are visible

👉 Learn how to decide, not just what to do

What Changes

Traditional:

  • Manual = something to read
  • Knowledge = information

New:

  • Manual = a decision system
  • Knowledge = decision structure

👉 Knowledge is used in real-time

Business Impact

DTM × Multi-Agent is not just operational improvement.

👉 It transforms the structure of knowledge itself

① Faster Knowledge Transfer

  • Decisions recorded as structure
  • Reduced dependency on individuals

👉 Faster training, lower risk

② Stable Quality

  • Same conditions → same decisions

👉 Reduced variability

③ Higher Productivity

  • Decisions are assisted instantly

👉 Faster operations

④ Risk Reduction

  • Policy + Risk + Human boundary

👉 Safer and accountable decisions

⑤ Competitive Advantage

  • Decisions accumulated and reused

👉 Knowledge becomes a strategic asset

Conclusion

Traditional manuals were optimized to store:

👉 Information

But what is truly needed is:

👉 Decision-making

Decision Trace Model × Multi-Agent bridges this gap by:

  • Visualizing decisions
  • Decomposing them
  • Making them reusable
  • Enabling continuous evolution

As a result:

  • Knowledge becomes structured
  • Decisions become reproducible
  • Quality stabilizes
  • Speed increases
  • Risk is controlled

👉 Operational improvement directly translates into competitive advantage

Decision Trace Model × Multi-Agent is:

👉 A system that transforms manuals from information into decision structures
👉 A foundation for accumulating reproducible decision-making

Ultimately:

👉 Organizations evolve from being dependent on individuals
👉 To continuously accumulating decision intelligence

This is the structural transformation of knowledge and management
enabled by Decision Trace Model × Multi-Agent.
