Let’s talk about your development environment.
Specifically, I’d like to chat with you about the virtual space where your data architecture team, software developers, and information curators do their development and testing work. A proper development environment is logically separated from the production environment, and is often further partitioned into different realms for initial development, data or functional validation, and user acceptance testing. For mature enterprise-ready environments, there is also usually a build and deployment process that automates the movement of code from one environment to the next, reducing the chance for human error when moving code through its paces and ultimately into the production environment.
I’d like optimistically to say that Tim is using strawmen here, but I’ve worked in (and sometimes created) pretty much each one of these.
