The triggers module is user-defined so you can automate processes, and define what you think is important, rather than a third-party.
Q: When would I ever use a trigger?
A: An event, such as an accident-related work order, triggers an action, such as “Send an email to the attorney”.
A: Create an inspection or a work order if asset condition is less than “X”.
A: Create an email to head of the department if work report accomplishment is less than/greater than “X”.
Send an email to service requestors when the work order status changes.
E-Mail crew members when they are scheduled on a work order.
These are just a few examples… but Triggers can do much more.
