I really love this article.

In practice a good strategy for companies is reduce unknown to a minimum, the Steve Jobs strategy, just focusing on very few products, with each having the less complexity possible(simplify and simplify).

Only focusing on very few products you could make perfection possible, estimates will be off, they always are when there is unknown, but at least completion will be finite (you will complete it!, which is number one issue with research work for example).

Sounds simple, but is really hard, leaving creative people on their own is dangerous for this reason, they could start new projects, not finishing anything.
