Lessons from DevOps Leadership Training

  • Dev” since I was developing amazing frontend apps using React,
  • and “Ops” since I was assigned the responsibility of maintaining the AWS infrastructure in term of production deployment, provisioning, HA.
  • In Bureaucratic culture, managers meet together to make decisions without involving teams (implementers) at an earlier stages.
  • In DevOps environment, Dev team ( Tech team) is involved at an earlier stage, owner ,accountable and self-organized . It has enough capabilities to take decision and move on.
  • DevOps environment is Performance oriented , delivering VALUE
  • Bureaucratic culture is Rule oriented, delivering TASK
  • In DevOps environment, a failure is a learning opportunity
  • In traditional IT, a failure leads to justice and scapegoating.
  • In DevOps environment, the Definition of “DONE” is “it’s ready to deploy/to be used by customer”.
  • In traditional IT, the Definition of “DONE” is “I did my job ” even if your work will be thrown against the wall 😏
  • DevOps transformation must comply with change management phases:
  • The first step in a successful DevOps transformation is VSM.
  • Value Stream Mapping or VSM is used to identify waste, it will never figure out the solution to remove the waste. Based on VSM findings, the team has to figure out solutions.
  • CI/CD is about the Speed, frequency but also reliability of deployment.
  • Measure everything. Don’t introduce new thing ( unit-test, CI ,… ) because others do it. Introduce it to remove the waste and bring value. Prove that it bring value using metrics. Measure before introduction of this new thing, and measure continuously after introducing it.
  • Time is the key performance metric as Time affects other metrics: Cost, Capacity.
