Felix Salmon speculates that Daniel Libeskind's plan won because Libeskind knew how to navigate the bureaucracy: "Given the very high standard of many of the shortlisted plans, I think that the ultimate reason that Libeskind won was that he was most attuned to the process, and most willing to present his ideas as a work in progress, something which could and should reflect the views of all the stakeholders in the site, and not just his own ego."
