Example: what is your biggest accomplishment

Using Scenario Outline & Examples in framework:
When I started to work in my last company 
we were in 5th Sprint of the project.
I started the work and understand the 
application and framework. After 2 sprints,
I figured out that almost nobody was using
scenario outline in my QA team. They had to
repeat almost each similar step because of that issue.
It was increasing redundancy and work load
over my team. Actually I like implementing DDT
in my frameworks as much as possible. 
Fortunately we were just at the beginning 
of the project and that was a chance to fix
this redundancy as soon as possible. 
I decided to talk with my QA lead to 
solve this issue. After telling to my QA lead,
he liked it and told me to prepare a 
short presentation to tell other team members
during retrospective meeting. 
Almost everybody embraced the idea and 
we started to use Scenario Outline for each
test case if we have to insert similar data
in the the same test case.
