>I am planning to use Business Object of type "QMSM" and event "Task Created" to trigger & send email to the managers to complete task.
That sounds right. I don't remember the exact business object & event, but if you have checked that these events are triggered when the quality notification is created, then you should be on right track.
Once a workflow is started, then the deadline functionality should be straightforward to implement. You can for example add another email step (for the reminder mail) to the workflow and set deadline for that. => It gets sent after 30 days. The important thing here is to set some kind of automatic completion procedure for your workflow, when the quality notification gets completed, so the reminder email will not be sent unnecessarily. Maybe there is an event (of QMSM) triggered, when the notification gets completed. If there is, then you just set that event to end the workflow.
