Quality Assurance (Shorthand QA) is a mod which adds multiple things related to quality. This includes:

• Base Quality - Adds quality to machines automatically, as if a quality module was added.
• Early Quality Unlock - Enables all qualities to be unlocked at the quality module technology.
• AMS Machines - Adds new machines which have additional module slots. These are slower than their normal counterparts, but the extra module slots are worth it.
• Improving Quality Modules - Multiplies the quality effect of all quality modules, so you don't need to wait extremely long to get your high-quality items.
• Quality Modules in Beacons - Allows you to place Quality Modules in beacons.
• Everything is configurable - Most likely the best feature of the mod, all of the above features are fully configurable, or at least they should be.
