Reflections…
Agile’s got it covered - so why DevOps?
Agile is ultimately about learning…
Confucius:“By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest;Third by experience, which is the bitterest.”
DevOps is a neat package
It covers what…
It covers what…and how
It hints at scale
…and focuses on culture
DevOps gets results*
*( Apply judiciously, not to be taken at meal times, results will vary, there is a risk of point fix and over investment )
Thanks!
