Progress for sanity

I don’t think anyone would dispute listening to a song, non stop on repeat, would make you sick of that song pretty quickly. 

Even if it was your favourite song.

Furthermore, if anyone actually had to endure a ‘Groundhog day’ scenario it would be safe to assume they would go insane quite fast.

Well I think the same applies with projects.

Endless iterations and lack of progress not only leads to questioning one’s sanity but entering a state of not caring anymore.

And you don’t want your team to not care anymore because then the quality of the output is going to take a big ole nosedive.
