The answer should follow SAR pattern:

S = Situation
A = Action
R = Result

For ex. sample situation:
Our depatment was getting a many complaints from customers on too many email notifications.

Action:
I did a research and found out that the problem was that each department handled notifications in they own ways. Our group took the responsibility and developed unified cross-company email notification system.

Result:
The system allowed to reduce amount of emails to our clients by combining and sending email according to notification priority.
