Clarifying Questions (5 mins)

• Looking at the global nature of NTT's IP network, I'm thinking about the geographical distribution of their enterprise customers. Could you provide more information on the primary regions or countries where NTT's enterprise customers are concentrated?

Why it matters: This helps us prioritize network improvements in high-demand areas. Expected answer: Concentration in North America, Europe, and Asia-Pacific regions. Impact on approach: Would focus on optimizing routes and infrastructure in these key regions first.

• Considering the enterprise customer focus, I'm curious about the types of applications or services these customers typically use that are most sensitive to latency. Can you share insights on the primary use cases driving the need for reduced latency?

Why it matters: Different applications have varying latency requirements, which will influence our optimization strategy. Expected answer: Mix of real-time communication, financial trading, and cloud-based services. Impact on approach: Would tailor solutions to address the most latency-sensitive applications first.

• Given that we're looking to improve an existing network, I'm wondering about the current state of NTT's infrastructure. What's the average latency across the network now, and are there specific routes or regions that are particularly problematic?

Why it matters: Establishes a baseline and helps identify the most critical areas for improvement. Expected answer: Global average latency of 100ms, with certain trans-oceanic routes experiencing higher latency. Impact on approach: Would prioritize improvements on the most problematic routes and aim for specific latency reduction targets.

• Thinking about NTT's position in the market, I'm curious about how their current latency performance compares to competitors. Do we have benchmarking data available, and what's the target latency reduction we're aiming for to stay competitive?

Why it matters: Helps set realistic goals and ensures our improvements will have a meaningful impact on NTT's market position. Expected answer: NTT is slightly behind top competitors, aiming for a 20-30% latency reduction to become industry-leading. Impact on approach: Would focus on innovative solutions that can provide a significant competitive advantage.
