21. Challenges
App upgrades are reviewed and users

23.  Involve backend teams in Mobile DevOps
 Focus on small incremental deployments
 Develop safeguard features (enforce upgrade, local
storage migrations, …)

Users are much less forgiving, and can
write public feedback for the app.

32. Challenge: Fragmentation

33.  Focus on the process (use it!)
 UX is critical, even for B2B apps
