I did exactly this recently at work. I had a feature set I've been wanting to add to the customer service portal but very little time approved so we built a part of it using very little dev time. The feature was very popular and well used. Everyone wanted it expanded to do more (basically a task system which saves people from ad hoc management of various tasks). Before too long, the full version was approved and was built in very short order because of lessons learned with the mvp.
