Components are subsections of a Product. E.g. the computer game + you are designing may have a "UI" + component, an "API" component, a "Sound System" component, and a + "Plugins" component, each overseen by a different programmer. It + often makes sense to divide Components in Bugzilla according to the + natural divisions of responsibility within your Product or + company.
Each component has a owner and (if you turned it on in the parameters), + a QA Contact. The owner should be the primary person who fixes bugs in + that component. The QA Contact should be the person who will ensure + these bugs are completely fixed. The Owner, QA Contact, and Reporter + will get email when new bugs are created in this Component and when + these bugs change. Default Owner and Default QA Contact fields only + dictate the + default assignments; + these can be changed on bug submission, or at any later point in + a bug's life.
To create a new Component:
Select the "Edit components" link from the "Edit product" + page
Select the "Add" link in the bottom right.
Fill out the "Component" field, a short "Description", + the "Initial Owner" and "Initial QA Contact" (if enabled.) + The Component and Description fields may contain HTML; + the "Initial Owner" field must be a login name + already existing in the database. +
