Large company with multiple teams and varying levels of people?
I met someone who worked on Office. He told me there were parts of Excel that used a shared code base for Mac/Win/Web, parts that were just Mac/Web with different Win components, and for the Excel graphs, the labels for the graphs were unified for all three platforms but drawing the graph was individual to each platform. Mac Office was a fork from years ago they're finally trying to rebase and bring back into mainline.
Some large companies aren't really unified entities with universal standards. You can be using a standard unified approach for the company and still be seated next to an intern not forced to use version control or a brand new Uni hire that's on a totally different process due to the team they get hired into.
