Be careful what you ask for
I believe that product teams get away with developing feature creep driven programs because a significant number of users believe more is better and will make purchasing decisions based on that thinking, sales are an enabler for bad development habits.
It would seem reasonable to think that only enlightened users can bring about better design through buying products that meet needs and not desires.
Therefor, good design processes alone will not make for a successful product. Organisations must engage with users in a two way dialog that educates both parties on needs.
