I found it fascinating how the team was still developing key plot points (let alone dialog/animation) down to the final few weeks/days before the film needed to be completed!
It completely kills your employees though: all those crunches to scrap tons of good work and replace it with new ideas; tons of stressful overtime. Ugh.
Working on the new service, everything is involving independently while product is figuring out what they want to sell in reality. This out-of-order execution seems like a feature of modern production, while consistency is left behind and only synchronize when they absolutely has to.
I have no opinion on this however, can't think of a better way myself.
