(National Archives & Records Administration in Washington) Requires a lot of thinking Not Easy Requires Collaboration Requires Executive Support Requires vertical thinking

Value of information is the amount a decision maker would be willing to pay for information prior to making a decision Bill Gates (Microsoft, 1981): “640K of memory should be enough for anybody” George Bell (Excite, 1999): Larry Page and Sergey Brin wanted $1M, George offered $750K, and Google walked Eric Schmidt (Google, 2009): Twitter is a "Poor Man's Email System" Imre Kabai, Chief Architect, SLAC National Accelerator Laboratory
