I'm not sure about *between* ASDF systems, but within a single one I
find myself using something like this:
(:file "foo" :depends-on (...whatever...)
:in-order-to ((compile-op (load-op "bar"))))

Interesting. When developing web-based apps, I do exactly the opposite!! ;-}
During periods of active development, I make the "foo.lhp" (Lisp-Handled
Pages) file look like this:
;;; Boilerplate for using ASDF from LHP page.
(let ((system :foo)
(flet ((this-page (request)
;; Ensure up-to-date each time.
(asdf:operate 'asdf:load-op system)
;; Hack to avoid a package read error the very first time.
(funcall (intern (symbol-name function) package) request)))
That way, ASDF verifies that everything's up to date and (re)compiled
on *every* web hit. That makes the development cycle *very* tight:
edit a bit, do a "save" in the editor, hit "Reload" in the browser,
and *boom*! Everything gets recompiled and the browser pops up the
new version of the page. [Or doesn't, and I look at the application
server's REPL and/or the Apache error log to figure out why.]
Yes, it costs a few extra cycles per page-hit, but IMHO it's well
worth it. [...and you did notice that "during periods of active
development" qualifier, yes?]
