SOLVING THE INCIDENTS AND OTHER UN-

PREDICTABLES IN A DEVOPS TEAM

2

Few would question that an issue

resulting in 10,000 users being

unable to access the system and

costing EUR 100,000 in revenue per

hour deserves special treatment,

compared to a feature under

development. But how do we make

sure that we choose the most

reasonable way of processing these

different types of work?

Remarks

DevOps team commits on delivering sprint backlog and reserved 10% reserved time for incidents

In case of no incidents during the sprint, the devops team would deliver more story points to account for 10% time for incidents

When the team can’t deliver more than 50% of committed story points due to a major incident the sprint is aborted and fresh sprint planning is done when the incident has been resolved

When the team needs more than 10% reserved time to solve incidents then number of committed story points in the sprint backlog are reduced proportionally 7
