How can LTI balance increasing user engagement for its virtual classroom tool against potential server load issues?

Introduction

Balancing user engagement and server load for LTI's virtual classroom tool presents a critical trade-off. We need to optimize the user experience while ensuring system stability and scalability. I'll analyze this challenge through multiple lenses, considering technical constraints, user needs, and business objectives.

Clarifying Questions (3 minutes)

• Context: I'm assuming this is an existing product with an established user base. Could you confirm if this is correct, and if so, roughly how many active users we're dealing with?

Why it matters: Helps gauge the scale of the problem and potential impact. Expected answer: Yes, with 100,000+ active users. Impact on approach: Higher user count would necessitate more careful load balancing and phased rollout.

• Business Context: Based on the focus on engagement, I'm thinking this might be a key driver for our revenue model. How does increased engagement translate to business value for LTI?

Why it matters: Aligns solution with business objectives. Expected answer: Higher engagement leads to increased subscription renewals and upsells. Impact on approach: Would justify investing more in engagement features, even at the cost of some server resources.

• User Impact: I'm guessing we have different user segments like students and educators. Are we seeing engagement issues across all segments or is this specific to certain user types?

Why it matters: Helps prioritize which user groups to focus on. Expected answer: Lower engagement among students compared to educators. Impact on approach: Would focus on student-centric features that don't overly burden the server.

• Technical: Considering the server load issues, I'm wondering about our current infrastructure. Are we using cloud services with auto-scaling capabilities, or do we have fixed server resources?

Why it matters: Determines the flexibility of our technical solution. Expected answer: Mix of cloud and on-premise servers with limited auto-scaling. Impact on approach: Would explore hybrid solutions and gradual migration to more scalable infrastructure.

• Timeline: Given the nature of educational products, I'm thinking we might be working within academic year constraints. Is there a specific timeline we're aiming for to implement changes?

Why it matters: Influences the scope and phasing of our solution. Expected answer: Aiming for major updates before the next semester starts. Impact on approach: Would prioritize quick wins and phase more complex changes.
