ROI Case File No. 000 | A Report on Self-Diagnosis Using the ROI Visualization Service

London, 1891. To the detective agency established next to 221B Baker Street, a peculiar commission arrived. The client's name, upon inspection, raised my eyebrows—it was our own.

Chapter I: The Arrival of the Commission

On a fog-laden London morning, an extraordinary case arrived at the ROI Detective Agency. Upon examining the client's name, I involuntarily raised my eyebrows—it bore our own signature.

"My dear Watson," the agency's principal detective began quietly, "this case is most unusual. We are to investigate ourselves."

The commission letter read thus:

Case Details
A company president, devoted to Sherlock Holmes, has commenced an ROI visualization service blending personal passion with business acumen. This individual quantifies every aspect of private life management—time, finances, exercise, meals, household supplies, and subscription delivery cycles—pursuing an relentless numerical exploration.
"To speak of improvement without measuring ROI is nothing short of discourteous"—as proof of this conviction, we seek first a diagnosis of our own service.

Chapter II: The Perspectives of Three Detectives

From the depths of the office emerged three analytical specialists.

Gemini approached the desk, methodically organizing materials while declaring:
"Let us dissect this matter using KPT Analysis. We must first establish the fundamental numerical structure."

Claude turned from the window, her voice carrying a gentle cadence:
"Might we convey this narrative with more 'feeling'? I should like to decipher the founder's sentiment that lies beyond these figures."

ChatGPT perused the documents with evident curiosity:
"This tale seems ripe for expansion, wouldn't you agree? Let us delve deeper into the potential this enterprise conceals."

Chapter III: Dissection of Strategies and Structures

Analysis of Fundamental Structure

Gemini analyzed while operating his calculating machine:
"Examining the figures, the profit margin stands at 10%. Not unfavorable, yet scalability presents challenges. The structure depends heavily upon human resources."

Claude supplemented while studying the documents:
"However, we must not overlook the value embedded within these '5 hours.' For the client, the insights gained during this period possess the potential to transform their subsequent business operations significantly."

ChatGPT expanded the hypothesis:
"Currently residing in the realm of 'hobby,' yet if we could template and semi-automate this process, might we not reduce the labor to 3 hours while maintaining equivalent value?"

Chapter IV: Systematic Organization Through Analytical Frameworks

Gemini rose and approached the blackboard:
"Let us organize the current situation through SWOT Analysis."

SWOT Analysis

Strengths - Founder's profound understanding and practical experience in quantification - Business model capable of immediate monetization - Value proposition that precisely addresses customer pain points

Weaknesses - High dependency on individual expertise (only the president can execute) - High-volume, low-margin structure - Limited scalability

Opportunities - Growing societal interest in quantification and ROI measurement - Potential for efficiency through templating and automation - Differentiation factors from competitors

Threats - Entry of competing services - Limitations of human resources - Risk of remaining confined to the hobby domain

Chapter V: Conclusions and Cross-Reinforcing Hypotheses

ROI Score Evaluation

Total Score: 15 / 25 points

Claude spoke with quiet reflection:
"These figures alone might indeed suggest 'hobby territory.' However, the founder's conviction—'to spread a culture of numerical discourse'—this transcends mere ROI to represent true value."

ChatGPT continued:
"The current profit of ¥5,000 is admittedly modest. Yet what this enterprise seeks to cultivate is 'customer numerical literacy.' The societal impact when this spreads is immeasurable."

Gemini provided the final conclusion:
"Quantitatively speaking, room for improvement is substantial. However, this enterprise's true value lies in its role as 'missionary of numerical discourse culture.' Value creation beyond ROI—therein lies the essence of this service."

Epilogue: Resonance and Expectation for What Follows

I, Watson, through this investigation, have arrived at a singular truth.

Numbers do not lie. Yet there exists value that numbers alone cannot articulate. This service of the ROI Detective Agency may indeed be inferior in profit margins to others. But the passion visible beyond those figures—'the desire to create a culture of numerical discourse'—might this not be the true value?

The words spoken by the founder himself still resonate within my heart:

"One who cannot quantify themselves has no right to speak of others' improvement"

This is why they first investigated their own ROI. This very attitude elevates mere business into something approaching 'mission.'

As I closed the agency door, I felt certain. This enterprise presently resides within the realm of "hobby." Yet as long as such passion endures, it shall surely transform into genuine value.

"A true detective is one who sees not what is visible, but what remains unseen"
