  To form comparative: hyödyllisempi (more useful); superlative: hyödyllisin (most useful).

Why is the word order Tämä ohjelma on todella hyödyllinen (SVO) instead of some other order?

Finnish is relatively flexible, but the unmarked (neutral) order is Subject–Verb–Object/Complement. Here:

2) on (verb)
3) todella hyödyllinen (complement)
This order clearly shows who is doing what and keeps the adverb directly before the adjective it modifies.
