JIRA makes it dangerously easy to implement overly bureaucratic processes. A certain kind of organization is drawn to it for that reason. Even a healthy organization switching to JIRA can get carried away with the tools now at its disposal. JIRA is a software product but also a social institution, an organizational philosophy. Sure, you can have the software without the attitude or vice versa, but use of JIRA is still a (weak) negative signal about the quality of an employer.
Turns out that the main thing protecting employee autonomy is the logistical difficulty of micromanagement. JIRA “solves” that problem.
