Let us as an example say that we have a custom application
with 1 million lines of code.

Let us say that there exist a standard solution with 5 million
lines of code which provides the same functionality plus a
lot extra (some useful - a lot irrelevant).

If the standard solution need 1% customization, then that
is only 50000 lines of code. And there may be a business
case. Obviously exact fit to requirements would need to
be evaluated, but potentially it could make sense.

If the standard solution need 40% customization, then
that is 2 millions line of code. And it seems very unlikely
that there is a business case. It would make more sense to
add to the custom application.
