Releases

It ended up being about more than just releases…

Everyone cares about testing

Fast and maintained automated checks

Bug fixes often take just minutes

What made it work Agree on an end goal

Stay risk focussed

Strong communication throughout the whole team

Use problems to drive positive change

Testers already have these skills

By managing the people and activities which make up the development process we can manage the risk level of a release.

Testing provides information to this process, which makes better-informed decisions possible.
