Best practice on designing parts for an assembly for modifications later on

Any tips on the approach to designing, which will make it friendly to make modifications to dimensions later on down the line?

I've had a small amount of experience using equations, and have found it to cause more complications than convenience.


Basically our assemblies consist of a frame, an enclosure and all the inner workings. The problem is spending so much time to resize all of the small inner workings, matching the holes, checking for interference. Also, a lot of times I would change 1 feature, then get errors from other features, so I fix those then some error from another feature down the tree. Just basically trickling down effect for each part that I would have to modify in order to get to the right size, consumes a lot of time.


I'd like to get an idea of how others design to make changes as friendly as possible.
