OFFLOAD

Offload processing that can be offloaded out of the production.

If there is a development tooling that can be split out of the main application and side loaded only during development, then DO NOT put such dev tooling into the application. (Example, Script monkey plugin/Chrome extension for web-development)

If something can be done by post processing data then do NOT build the processing into production application.

Yes development niceness is an important aspect of software health. But if we can add such niceness WITHOUT increasing the risk of production software, then we absolutely must do so.
