ROI Case File No.363 | 'Meditech's One-Handed Meeting Minutes'

Chapter 1: Recording With One Hand Occupied — The Quagmire of "He Said, She Said"

The day after resolving VirtuShoes' RFM case, a consultation arrived regarding meeting minute creation in medical settings. Volume 29, "The Pursuit of Reproducibility," Case 363 tells the story of discovering true value through competitive advantage.

"Detective, our nurses take meeting minutes with one hand occupied. They take notes while talking to doctors on PHS. They receive instructions during patient care and take handwritten notes. Omissions occur in content, and 'he said, she said' troubles arise. And we spend 480 hours per month creating meeting minutes."

Kentaro Tanaka, Operational Improvement Director of Meditech, a Yokohama native, visited 221B Baker Street with an exhausted expression. In his hands, he held copies of hastily handwritten nursing records, contrasting sharply with the latest AI meeting minute tool proposal document titled "AI Transcription Tool Proposal 2025."

"We provide IT systems for hospitals. 120 employees. Annual revenue of 3.5 billion yen. However, meeting minute problems at our client hospitals have become serious."

Meditech's Current State: - Founded: 2008 (Medical IT system development) - Employees: 120 - Annual Revenue: 3.5 billion yen - Clients: 8 general hospitals, 22 clinics - Issues: Nurse meeting minute creation work hours, recording accuracy, hands-free support

Deep crisis resonated in Tanaka's voice.

"At client Hospital A (450 beds, 280 nurses), the following meeting minute creation occurs. First, phone communication with doctors. They receive patient care instructions from doctors via PHS. They hold the PHS with one hand and take notes with the other. However, during patient care, both hands are occupied and notes cannot be taken. Relying on memory causes omissions."

Meeting Minute Creation Reality:

Case 1: Phone Communication With Doctors (PHS Use) - Frequency: 8 times/day per nurse - Call duration: Average 3 min/call - Note creation time: 5 min after call/call - Clean copy time: 10 min after shift/call - Total time: 18 min/call - 280 nurses × 8 calls/day × 18 min = 672 hours/day - Monthly (22 working days): 14,784 hours/month

Case 2: Hospital Internal Meetings (Once Weekly) - Participants: 20 department representatives - Meeting time: 2 hours/meeting - Meeting minute creator: 1 person - Meeting minute creation time: 4 hours after meeting - Clean copy and confirmation: 2 hours - Total time: 8 hours/meeting - Monthly (4 meetings): 32 hours/month

Case 3: Patient Family Interview Records - Frequency: 10 cases/day - Interview time: Average 30 min/case - Record creation time: 20 min after interview/case - Total time: 50 min/case - Monthly (22 working days): 10 cases × 22 days × 50 min = 183 hours/month

Total Monthly Meeting Minute Creation Time: - 14,784 hours + 32 hours + 183 hours = 14,999 hours/month - Approximately 15,000 hours/month (1,875 days/month, 8-hour conversion)

Tanaka sighed deeply.

"There are additional problems. Recording accuracy. Handwritten notes are sometimes illegible due to hasty writing. Doctors sometimes say 'I never gave that instruction.' 'He said, she said' troubles occur 5 times per month. And nurses request 'a hands-free recording tool.'"

Chapter 2: AI Meeting Minute Tools as an Option — Does It Really Have Competitive Advantage?

"Mr. Tanaka, do you believe implementing AI meeting minute tools will solve all problems?"

Tanaka answered my question immediately.

"Yes, that's our expectation. Many AI meeting minute tools exist in the market. However, we don't know which to choose. And we're uncertain whether they truly have competitive advantage."

Current Understanding (Tool Implementation Model): - Expectation: AI meeting minute tools solve everything at once - Problem: Tool's competitive advantage remains unclear

I explained the importance of evaluating competitive advantage.

"The problem is the idea that 'implementing AI meeting minute tools is the end.' VRIO—Value, Rarity, Imitability, Organization. We evaluate tools' competitive advantage from these four perspectives. And by selecting truly valuable tools, we achieve reproducible operational improvement."

⬜️ ChatGPT | Catalyst of Conception

"Don't implement tools blindly. Evaluate competitive advantage through VRIO and select truly valuable ones"

🟧 Claude | Alchemist of Narrative

"Meeting minutes are always 'records of truth.' Their accuracy supports medical quality"

🟦 Gemini | Compass of Reason

"Evaluate through VRIO. Value, Rarity, Imitability, Organization. What satisfies all four has true competitive advantage"

The three members began analysis. Gemini developed the "VRIO Framework" on the whiteboard.

VRIO's Four Elements: 1. Value: Does it generate economic value? 2. Rarity: Is it a rare resource? 3. Imitability: Is imitation difficult? 4. Organization: Can the organization utilize it?

Chapter 5: Detective's Diagnosis — Discovering Competitive Advantage Through VRIO

That night, I contemplated the essence of VRIO.

Meditech held the simple idea that "implementing AI meeting minute tools is the end." However, many tools exist in the market, and not all possess the same value.

By evaluating through VRIO framework, tools with true competitive advantage became clear. Medical-Specialized AI Meeting Minute Tool C satisfies all four elements: Value, Rarity, Imitability, and Organization.

Medical terminology recognition accuracy 98%, 100,000-word medical terminology dictionary, medical chart system integration API, compliance with medical information handling regulations. These are imitation-difficult resources built through 5 years of R&D and partnerships with 450 medical institutions.

Implementation achieved 75% reduction in meeting minute creation time (14,784 hours → 3,696 hours), annual reduction effect of 430.2 million yen, ROI 2,443%, payback period 14 days.

"Don't implement tools blindly. Evaluate competitive advantage through VRIO. What satisfies all four elements—Value, Rarity, Imitability, Organization—has true competitive advantage. Tools with sustainable competitive advantage achieve reproducible operational improvement."

The next case will also depict the moment of discovering true value through competitive advantage.

"VRIO—Value, Rarity, Imitability, Organization. Evaluate competitive advantage from four perspectives. What satisfies all generates sustainable competitive advantage"—From the Detective's Notes
