There's a lot of lessons to be learnt from observing how product management and development teams fail to manage software products properly.
One of the examples I've seen is the Mi A1/A2 camera setting for the camera.
If you look at this image, you'll notice that it is reversed.
This is due to the fact that the manufacturer, Xiaomi, did not think through the software design process completely..
When do you use the front camera of a phone? When you want to take a wefie/selfie.
When you take a selfie, you generally want the photo to be how you see it. Yet, Xiaomi set the default setting for this option, which is "Mirror front camera" to On, when it should be set to Off.
As such, all over the world and social media, a lot of photos were taken in reverse. Most of the time, it's okay, until you see photos with words that appear to be placed beside a mirror, and you're looking at the photo using the mirror.
A method pointer is now the same as a global procedure, ie, procedure of object = procedure.
