2. Use simple Google forms
3. Have a joker for each session available
4. Remind them (email & phone call)
5. Reward them (20 €, remember ‘attention’)
6. No show rate: 5-10% (Additional shows, too!)
7. 150 emails required for one interview
stefan@age-of-product.com

3. Post-interview muffins only
4. Crew: max. 2
5. Observers: 2-3
6. Let (trained) stakeholder run interviews
