Recently, while I was using the MS Excel to look at some reports, I noticed a small yet interesting change makd to the 'Sort & Filter' tool. Many times while observing users I noticed that the best of them get confused when choosing between Ascending/Descending to sort data. Its not a big deal and people don't even realize this. But when I analyzed the problem, I realized that this 'decision making' actually comes in between the user and his task to sort the data, its a context switch.

In the new Excel, they have removed all ambiguity and simply called the Buttons 'Sort A to Z' and and vice versa OR Sort 'Smallest to Largest' and vice versa for letters and numbers respectively.

   

Just keep it simple, Dont Make me Think.
