Common Experiences

Team Objectives

Defence vs Attack?

DevOps Culture Feels Like• A sports team playing to win–Multi-part objectives• Score points• Defend

– Success comes from the shared, joint objectives

– Optimising for only points or defence is not effective

In Sync?

In Sync

DevOps Culture Feels Like• A band of musicians– In time, in tune, ‘in the groove’ – Different specialisms, one goal

Summary

DevOps Culture Feels Like• A sports team playing to win–Multi-part objective: score, prevent

loss• A band of musicians– In time, in tune, ‘in the groove’

• A reliable vehicle– Repairs done, journeys completed

DevOps Culture Feels Like• Never ‘them’ or ‘they’– ‘Us’ or ‘we’ instead

• Ops pairing with Devs on code– Logging, monitoring, <operability>

• Ops using version control (!)• Devs concerned with operability• No ‘project code’ or budget conflicts
