You don't. Well, you do, but not without losing stuff. Basically, you shoot from the hip, with less information. Some orgs already do this. They glace at resumes, talk to a few people briefly, and make a gut decision. Or you hire more known quantities (friends, and former colleagues). There are huge drawbacks to either approach, but those are the other options. You get less information if you shorten the process, however there's always a great deal of uncertainty when hiring someone new, no matter what you do.
