Why is consistency important in product design?

Overall consistency creates a sense of structure for the viewer. Which helps them understand more about your product, idea or message. It also helps to form a framework for a designer to work within. Saving them time and focusing the work they create so it is as successful as possible!

Which component is used for maintaining consistency across changing platforms?

A brand style guide is probably the best way to keep everyone on the same page with your brand. Brand style guides tend to be comprehensive in the use of the brand's logo, verbiage and design elements, but they also can include things like using specific words (or omitting specific words) from marketing verbiage.
