If enterprises were really focused on saving employee's time, Jira wouldn't sell. At least not the bog slow SaaS version
Saving time (==saving money) is something you can sell to companies. But above all, they are willing to spend on saving their managers time. The higher up the hierarchy, the better. If that involves wasting a lot more time for the underlings, then so be it. The underlings aren't the ones making the purchasing decisions after all
i dont think jira (or linear or any other ticketing platform) is about saving anybody time. they know on some level that they are all a burden.
but they will gladly take the productivity hit from that time sink because it gives them teh ability to track employees. they'd rather know that everybody is working at 80% productivity than release that burden and just trust them. it's either this or filling out frustrating timesheets.
