One good example of this concept is this bottle of ibuprofen. Because the industry standard is to have a child-proof cap that must be pushed down and rotated at the same time, we know exactly what to do with it. We also see the tamper seal and labelling. Because everything about this product is so standardized, we do not have difficulty using it.

Recently, I downloaded a Facebook Messenger desktop application. Something strange that I noticed is that when you want to go to the setting on an Apple device, you must first go the main application menu, then click preferences, and then a window pops up where you must again click “settings”. This is a poor example of consistency and standards because it is confusing to have to find the settings menu twice in a very redundant way.

To make it better, I would simply consolidate all the options from both menus into one on first outer menu, and have the setting window pop up when you click “preferences.” This would make it easier to find all the options one would expect to find under a main menu for an application such as this.
