Is this any feature in JIRA without completing predecessor task, successor task (FS) will not start.

Hello,

You can not do it out of the box. You would need an app like Power Scripts, ScriptRunner, JWME, MyGroovy, Groovioli and so on.

If you want to use the Power Scripts app, then you could create a condition for the In Progress status with a code like this:

if (parent.status == "To Do" {

    return false, "Parent status is To Do, you can not start this task";

}

return true;
