In this chapter, we have looked at fields in JIRA. We have looked at how JIRA is able to extend its ability to capture user data through custom fields. We have also explored how we can specify different behavior for fields under different contexts through the use of field configurations and schemes. In the next chapter, we will expand on what we have learned about fields by formally introducing you to screens, and how to combine fields and screens to provide your users with the most natural and logical forms, to assist them in creating and logging issues.
