Jesse Robins at O'Reilly Radar - Operations is a competitive advantage... (Secret Sauce for Startups!):

"In my experience it takes about 80 hours to bootstrap a startup. This generally means installing and configuring an automated infrastructure management system (puppet), version control system (subversion), continuous build and test (frequently cruisecontrol.rb), software deployment (capistrano), monitoring (currently evaluating Hyperic, Zenoss, and Groundwork). Once this is done the "install time" is reduced to nearly zero and requires no specialized knowledge."
