ROI Case File No. 023 | Crisis Lurking in Personal Dependency—The Shift Management Near-Accident Incident

Chapter I: An Incoming Request

1891 London, a telegram arrived at the detective office at 221B Baker Street. The sender was a factory manager from a manufacturing company. The content, though brief, was filled with urgency.

"That night, the shift leader noticed the placement error..."

Watson frowned while reading the telegram aloud. "Holmes, what kind of case is this? Something seems to have happened at a factory..."

"Watson, this isn't merely a personnel trouble. A quiet crisis called 'personal dependency' has finally surfaced."

The telegram continued:

The person solely responsible for night shift scheduling fell ill. When a replacement tried to reorganize the assignments, dangerous placements violating legal standards were discovered. Though found just before a serious accident, fundamental solutions are needed.

"Let's break this down with a KPT Analysis, shall we?"

Gemini calmly organized the situation.

Keep (points to continue) - High-precision shift creation through the responsible person's experience and intuition - Track record of operation without major troubles until now

Problem (issues) - Single point of failure due to complete personal dependency - Inadequate checking system for legal constraints (Labor Standards Act, safety standards) - Lack of handover materials and procedure manuals - Absence of backup personnel

Try (improvement measures) - Documentation and structuring of shift creation rules - Automation of constraint condition checking - Building multi-person creation systems

🟧 Claude | Consideration by the Alchemist of Narratives

"Perhaps we should convey this with more 'feeling'?"

Claude gazed at the truth behind the story.

"Personal dependency is a quiet crisis"

It appears efficient on the surface. A veteran's experience and intuition instantly create shifts meeting complex conditions. However, invisible vulnerability lurks beneath.

Like a beautiful building supported by a single pillar. Usually stable, but when that pillar breaks, everything collapses.

The psychological resistance from the field is understandable. Anxiety about changing long-familiar methods, fear of new systems. We need to embrace these emotions while helping them accept change.

⬜️ ChatGPT | Hypothesis Development by the Catalyst of Ideas

"That's quite intriguing to explore further, isn't it?"

ChatGPT delved into the background.

Why did shift management personal dependency occur at this company? Likely through this progression:

1. Initial stage: Small-scale, simple shift creation
2. Expansion period: Business complexity increased, but "capable person" handled it
3. Stable period: Smooth operation, personal dependency dangers overlooked
4. Crisis occurrence: Sudden absence of responsible person surfaces problems

This structure could occur in other operations too. Sales customer management, accounting monthly processing, system maintenance...

Chapter III: Dissecting Policies and Structures

Field Investigation Results

When detectives visited the factory, shift management realities became clear.

Conventional Creation Process: 1. Responsible person mentally tracked all employee situations 2. Relied on memory to check legal constraints (within 40 weekly hours, consecutive workday limits, etc.) 3. Created manually or with simple spreadsheet software 4. Required 24 monthly hours to complete

Deep Problem Structure: - Over 15 constraint conditions existed (labor law, safety rules, individual preferences, etc.) - Complexity where one shift change affects the entire system - Structure where personal knowledge accumulated but wasn't shared

Chapter IV: Systematic Summary of Analysis

🟦 Gemini's Structural Analysis

"Let's organize the problem's essence with 5W1H"

What: Complete personal dependency in shift creation operations Who: Dependence on one specific person When: Problem discovered during sudden absence due to illness Where: 24-hour operating manufacturing site Why: High-complexity operations entrusted to individual capability How: Solution through structuring, automation, and multi-person systems

SWOT Analysis: - Strengths: High expertise, past track record - Weaknesses: Personal dependency, impossibility of handover - Opportunities: Efficiency through AI and systematization - Threats: Legal violation risks, accident occurrence possibilities

Chapter V: Cross-Reinforcement of Conclusions and Hypotheses

🟧 Claude's Storytelling

Behind this case lies a deep problem modern organizations face.

In pursuing efficiency, a culture of "leaving it to capable people" took root. However, that efficiency was a castle built on sand. A fragile structure where everything stopped functioning when one person fell ill.

The solution isn't mere system implementation. It's transforming organizational culture and building sustainable mechanisms not dependent on individual capabilities.

⬜️ ChatGPT's Insight Articulation

Lessons from this case:

1. Importance of prevention: Measures before problems surface
2. Value of structuring: Documentation and sharing of tacit knowledge
3. Redundancy design: Eliminating single points of failure
4. Preparation for change: Process of escaping personal dependency

ROI perspective results: - Work hour reduction: 24 monthly hours → 4 hours (83% reduction) - Risk avoidance: Potential cost reduction by preventing legal violations and accidents - Organizational strengthening: Improved resilience to resignations and absences

🟦 Gemini's Decisive Hypothesis Reinforcement

Final structural analysis based on data:

Similar to laws of mobile optimization's sales impact, shift management structuring directly affects safety and profitability.

• Potential loss per accident: Average ¥5 million to hundreds of millions
• Fines and business suspension risks from legal violations: Tens of millions annually
• Personnel cost savings from work hour reduction: Approximately ¥2 million annually

Investment recovery period: 6-month recovery against ¥2 million system implementation costs.

Epilogue: Resonance and Future Expectations

Watson reflected on the case resolution while contemplating.

This case appeared superficially as a shift management problem. However, what lay beneath was structural vulnerability facing modern organizations.

A chance event—one person's illness—exposed the organization's hidden crisis. Without this "accident," problems might have continued growing underwater, causing more serious consequences.

"Structure, not human capability, should protect safety"

This is the most important lesson from this case.

Rather than depending on individual excellence, creating mechanisms that maintain the same quality regardless of who fills the role. That's true organizational strength and the foundation for sustainable growth.

The detectives head toward solving new cases. To discover organizations' invisible problems and provide structural solutions.

【Case Resolution Points】 - Problem identification: Complete personal dependency creating organizational vulnerability - Root cause: Over-reliance on individual expertise without knowledge transfer systems - Solution approach: Structuring, automation, and multi-person backup systems - Risk mitigation: Prevention of legal violations and safety incidents - ROI: 83% work hour reduction with 6-month investment payback

Final Insight: "A true detective sees not what is visible, but what is invisible"

【Case Summary】 - Problem: Crisis from complete personal dependency in shift creation - Solution: Introduction of structuring, automation, and multi-person systems - Results: 83% work hour reduction, significant risk mitigation, organizational strengthening - Lesson: Structure, not individual capability, should protect safety
