In the previous article, we discussed an example of applying the Decision Trace Model to the manufacturing industry.
The Decision Trace Model is often explained as a technology for AI systems.
However, its original purpose is to provide a framework for structuring human decision-making processes and preserving them in a reusable form.
For this reason, the model can be applied not only to manufacturing but also to any workflow where human decision-making plays a role.
An important point is that while the basic structure of the Decision Trace Model remains the same, the way it is applied varies slightly depending on the characteristics of each domain.
For example:
In manufacturing, the focus is mainly on
-
design options
-
risks
-
rejection reasons.
In contrast, in the retail domain, the focus shifts to
the relationship between store decisions and sales outcomes.
In this article, we will explore how the Decision Trace Model can be applied to the retail industry.
In Retail, “Outcome Data” Is Already Highly Managed
In many retail companies, systems for managing outcome data are already well established.
For example:
-
Real-time collection of POS data
-
Monitoring of sales, customer counts, and inventory
-
Databases for ordering history and sales history
-
Visualization of KPIs such as waste rates and inventory turnover
-
BI dashboards for analyzing store performance
In other words,
the management of outcome data — especially sales data — is already highly advanced.
However, another problem exists at the operational level of retail.
What Is Truly Missing Is the Process of Store Decisions
In retail stores, a large number of decisions are made every day.
For example:
-
Changing product displays
-
Running promotional sales
-
Adjusting order quantities
-
Modifying product placement
However, in most cases, the only data that remains within the company is
the outcome — sales.
What is not recorded includes:
-
why a particular display change was made
-
why a specific promotion was implemented
-
why a certain order quantity was selected
-
which strategies were considered and which were rejected
In other words, what is missing is
the decision-making process behind store operations.
Are Store Decisions and Sales Outcomes Treated as Organizational Assets?
Retail companies usually possess vast amounts of data such as:
-
sales data
-
inventory data
-
POS data
However, what is truly important is understanding
which decisions produced which outcomes.
For example:
-
Did a display change contribute to higher sales?
-
Did a promotion increase customer traffic?
-
Did an ordering decision lead to increased waste?
In most cases, these relationships are not stored as structured data.
As a result:
-
successful initiatives cannot be replicated
-
the causes of failures remain unclear
Does the Know-How of Store Managers Remain in the Organization?
Successful stores almost always have capable store managers.
Through experience, they make decisions about:
-
how to design product displays
-
when to run promotions
-
how to adjust order quantities
However, the decision processes behind these actions often exist only as
the personal experience of the store manager.
As a result:
-
when a manager is transferred, their knowledge disappears
-
successful store practices cannot easily be replicated in other locations
What Is Needed Is the Structuring of the Relationship Between Decisions and Outcomes
The key requirement here is
structuring store decisions.
It is not enough simply to record logs.
For example, companies could:
-
record meetings
-
write daily reports
-
store chat messages
While these methods preserve information, it is still extremely difficult to extract:
-
what strategies were considered
-
what concerns existed
-
why a particular decision was ultimately chosen
To address this problem, we introduce the
Decision Trace Model.
Store Decision Trace Model
In the retail domain, the Decision Trace Model can be structured as follows.
Context
The situation in which the decision was made.
Examples:
-
weather
-
day of the week
-
competitor activity
-
inventory levels
-
seasonal events
Option
Possible strategies considered.
Examples:
-
display changes
-
promotional sales
-
order adjustments
-
shelf arrangement changes
Concern
Concerns raised during the decision process.
Examples:
-
risk of waste
-
risk of stockouts
-
margin reduction
-
operational workload
Rejected Option
Strategies that were considered but not adopted.
Examples:
-
deep discount promotions
-
additional ordering
-
shelf restructuring
Reasons:
-
waste risk
-
profit reduction
Decision
The strategy that was actually adopted.
Examples:
-
milk promotion
-
entrance display
Outcome
In retail, this element is especially important.
Examples:
-
sales
-
waste
-
inventory turnover
-
customer traffic
Through this structure, it becomes possible to analyze the relationship between
store decisions → outcomes.
How to Apply the Decision Trace Model in Store Operations
In practice, implementation should be carried out gradually.
Phase 1
Structuring store decision logs.
Approximately 200–500 store decisions related to areas such as:
-
display changes
-
promotional strategies
can be manually structured.
Phase 2
Search for similar strategies.
Using accumulated decision data, the system enables searches for:
-
similar initiatives
-
past decisions
-
patterns of concerns.
Phase 3
AI-assisted input.
Using technologies such as:
-
Graph Neural Networks (GNN)
-
Large Language Models (LLM)
-
machine learning
the system can support:
-
automatic extraction of decision content
-
suggestion of potential concerns
-
retrieval of past cases.
Phase 4
Analysis of successful patterns.
With accumulated data, it becomes possible to identify:
-
sales improvement patterns
-
waste reduction strategies
-
store operation best practices.
What Changes When This System Is Introduced?
Several important changes occur when this system is implemented.
Successful initiatives become reproducible
By analyzing why sales increased, companies can
replicate successful patterns across stores.
Store manager know-how becomes an organizational asset
The decision path of store managers is recorded as:
Option → Concern → Decision → Outcome
This allows similar decisions to be reused in other stores.
Operational accountability improves
For example:
Instead of simply saying,
“a promotion was run,”
it becomes possible to explain that
“Considering the risk of waste, a small-scale promotion was chosen instead of a large discount campaign.”
This enables structured explanations of decisions.
How This Differs from Traditional Retail DX
Traditional retail DX initiatives typically focus on:
-
POS analysis
-
sales analysis
-
demand forecasting
-
inventory optimization.
However, these approaches deal primarily with
outcome data.
The Decision Trace Model focuses instead on
the decisions themselves.
Conclusion
Traditional retail DX focuses on:
-
analyzing sales
-
optimizing inventory
-
forecasting demand.
However,
the decisions made in store operations themselves are rarely captured as data.
The Decision Trace Model:
-
structures store decisions
-
preserves rejected strategies
-
records the relationship between decisions and outcomes
and thereby
turns operational knowledge into organizational assets.
The true value of retail does not lie merely in sales.
It lies in the decisions that generate those sales.
The Decision Trace Model provides a framework for transforming those decisions into lasting organizational knowledge.
