what is the purpose of jira
It provides bug tracking, issue tracking, and project management functions. Although normally styled JIRA, the product name is not an acronym, but a truncation of Gojira, the Japanese name for Godzilla, itself a reference to JIRA's main competitor, Bugzilla.IRA includes tools allowing migration from competitor Bugzilla. Compared to Bugzilla, JIRA is more internally customisable. Bugzilla has a single, fixed, state machine to represent the lifecycle of a 'bug'. All such bugs are assumed to follow the same fixed pattern of detection, repair and test.
