16. are we building two separate beasts...
17. ...or one solution?
18. * full stack ownership (awareness) * cross-functional team
19. Operating system Server software Datastore Application * full stack ownership (awareness) * cross-functional team
20. Operating system Server software Datastore Application DBA development CTO operations * full stack ownership (awareness) * cross-functional team
21. Operating system Server software Datastore Application DBA development CTO operations dysfunctional segregation? * full stack ownership (awareness) * cross-functional team
22. Operating system Server software Datastore Application team cross-functional team? * full stack ownership (awareness) * cross-functional team
23. “where the team ‘tries to go the distance as a unit, passing the ball back and forth’” Hirotaka Takeuchi, Ikujiro Nonaka New New Product Development Game, ’86 * full stack ownership (awareness) * cross-functional team

25. development affects ops
26. design install develop monitor test patch .... development operations +
27. awareness we must be aware of the other teams and disciplines around us in order to...
28. patience ...have patience for us and for them to...
29. insight * ...gain insight into our respective discipline, skill sets and challenges... * see each others work * be close (whatever that means)
30. understanding ...so that we can come to a better understanding about all parts of the equation
