It's not uncommon for technology companies to over promise and under deliver. We just aren't used to it from Apple because of their secretive nature. They released a new MacBook recently and we don't know whether that was on time or months late simply because Apple never mentioned it before the product was released.

Whether the fault lies with individuals or the structure of the organisation is a more interesting question. I wonder if American corporations would take a more individualistic approach to this compared to their European and Asian peers.
