    • Personal Growth workshops

      Introduced monthly hands-on training workshops.

      By using in-house experts, to deliver 1/2 day, regional hands-on, realistic, workshops, the program gives engineers a chance to use emerging technologies on realistic use cases, rather than under idea situations. For example, it's easy to setup a Kubernetes demo, but most introductions, don't cover dealing with sidecars and statefull containers. The workshops also gave experienced team engineers a change to showcase their skills and produce content for our knowledgebase. As the workshops were run separately it was also an opportunity for the American and European offices to collaborate on training materials, without having to deal with time-zones for the delivery.

      Keywords: ChatOps, Knowledge Sharing,
      Technologies: Slack,

      Standardizing the company on a single chat and knowledge base, made it much easier for new colleagues to get up to speed. Most of this was focusing on making the case for unifying the tooling (in this case Slack and Atlassian), making sure there was a path forward for all the teams involved that wasn't seen as a regression was important. The end result was much more cross-department knowledge sharing, mostly along technical lines, however it also helped organize events (both globally and office specific).
