Slack
Most Slack errors come from being offline or losing sync. When I cut my WiFi, Slack held my messages as drafts. I could retry with one tap. The real cost of failure here is lost productivity. If a message looks like it sent when it didn’t, teams start to question the tool. And when trust drops, organizations can switch to Teams or other tools fast. Slack’s recovery flow keeps people in the workspace.
Uber
Uber loses money the moment a ride fails. When I tried to request a ride with an expired card, it stopped me and pushed me straight to updating my payment method. When I cancelled mid-request, it saved my destination so I didn’t have to start over. The app is built to keep the ride alive. The cost of an error is immediate: a lost fare, an annoyed rider, and possibly a driver who gives up and logs off. Clear next steps help Uber protect the ride completion funnel, which is where all the revenue comes from.
Banking Apps
For banks, the cost of error is trust. If a transfer looks wrong or a balance looks off, users can leave for good. Recovery flows focus on reassurance and clear explanations. Money has to feel safe, even when the system fails.
