Fit and Finish is how well all the pieces fit together and how satisfying a product is to use. A product might be completely functional but not satisying to use. A good fit and finish can make the difference between something we love, and something merely useful.
Some markers of good fit and finish:
* Do the different functionalities and components complement each other well? * Are animations and transitions satisfying and smooth? * Is the use of spacing, materials and color consistent? * Does the product behave well in adverse conditions?
Additionally, a big part of fit and finish, is having good taste.
