Jira issues all use custom fields in some way. Almost all fields are custom, whether it be from apps like Advanced Roadmaps (now included in Data Center and with Jira Cloud Premium) or from Admins creating the fields. The fields come in all forms too, such as labels, text, numbers, dropdowns, and so many more. Without custom fields, the data input into Jira would be hard for many users to interpret and stay caught up on, however, they also have downsides too, such as performance impacts.
With that said, how do other enterprises handle custom fields? Are there any that are restricted due to performance impact, whether that be system-based or from a user standpoint?
Are there any everyone really likes and recommends?
How about naming conventions and standardizing?
Are there any practices that you’ve seen implemented around configurations?
Any insights with any aspects of custom fields are more than welcome!
