Perhaps, it depends on the project of course, and how many others depend 
on you doing your work the way you were told.  If you're developing a 
library for others to use, and don't do it the way it was designed, then 
you've caused problems for many others who were expecting to design 
their application one way.  On the other hand, if you're developing an 
internal tool without interfacing with anyone else, then as long as you 
meet the functional requirements, your "internal improvements" shouldn't 
be a concern, as long as they are *real* improvements.

It can be a difficult judgement call, but it is sometimes better to 
start with the way you think it should be done (especially if it takes 
less time to do that), and then "build the bridge" to the way they 
wanted it to be done.  Building an ugly facade in front of good code is 
better than building a pretty facade in front of bad code.  Especially 
if you're maintaining the code more than the facade.
