Attention Cliff: Diagnosing a Failing Virtual Session Agenda
Objective: Given a real-shaped virtual session agenda, find the design defects that cause the 25-30 minute disengagement cliff the lesson names, and separate them from plausible-but-fine agenda choices.
You're a virtual events coordinator at Zendesk, reviewing a draft agenda for an upcoming customer webinar before it goes live to registrants.
Read the draft session agenda, flag every defect against the lesson's attention-decay framework, and separate real defects from acceptable choices.

Free and sufficient for a short teardown checklist
The process
Specimens to review
Identify every defect in this agenda that the lesson's data predicts will cause drop-off, and note which elements are actually fine.
DRAFT AGENDA: 'Customer Success Deep Dive' (60 minutes) 0:00-0:05 Welcome and sponsor thank-yous 0:05-0:50 Panel discussion: three customer success leaders discuss retention strategy (no audience prompts scheduled) 0:50-0:55 Q&A (moderator reads 2 pre-submitted questions) 0:55-1:00 Closing and registration link for next event Registration confirmation email says: 'Save your seat, 500+ signed up already!'
Specimen: synthetic, realistic
Final deliverable
A marked-up agenda with each defect labeled by severity and lesson reference, plus a corrected version with interaction points inserted before minute 20.

Nubank Webinar Teardown (excerpt) DEFECT (critical): 40-minute unbroken product demo, no poll or chat prompt scheduled Fix: insert a 2-question poll at minute 15 and a live chat prompt at minute 30 DEFECT (moderate): registration email says '800 registered' with no attendance framing Fix: track and report watch-time completion rate instead
Success criteria
You're done when you can:
- Correctly flags the 45-minute unbroken panel as the critical defect
- Correctly identifies the sign-up vs. attendance conflation as a defect
- Does not flag genuinely acceptable elements (sponsor thank-yous, session length, closing CTA) as defects
