Careful architecture doesn't guarantee anything, but it does decrease the
chance of ending up with a ball of bandaids.

So you have two choices.  Architect with some idea of the future or none at
all.  In many case the "some idea" will be good enough to be useful.

It is bad architecture, or usually the lack of even considering the overall
architecture that got them into this mess in the first place.  Anyone can
make the first 20% of features work.  With a bad architecture, once you get
to the 80% level or so, adding new features breaks old ones to a point where
the project stalls and the consultant is called to "finish" the last 20%.
