How do we use it?

Use the 3 steps from the BAR Key to make some changes to a product like a laptop.

B = Bigger. Make one part of the product bigger or more important in terms of its use. 

A = Add. Add a part or an additional product to the laptop

R = Replace. Detach something from the product, and replace it with something else. 

Why its important?

Acronyms (like BAR) are extremely useful when we want to remember how to innovate new things. This particular acronym activates your memory when you want to redesign something.
