Question 1 of 30

Tell me about some of the process improvements you have implemented in the past.

"In my last job, it became apparent that the time to implement a software application exceeded the organization's expectations. I was assigned to analyze and reduce the start-up time for a new app. I examined the workflow and found that there was a lot of interchange between the DevOps Group and the operations team when a new app was released. I determined that this was due to a lack of proper documentation concerning the app from the DevOps team. I collaborated with both groups to determine what information was needed to expedite the implementation of a new piece of software. We then established metrics around this information. Once the new system was implemented, the start-up time for a new application was reduced by 50%."
