Prior　to　the　availability　of　enterprise　EDM,　locating　a　document　over　a　LAN　could　be　difficult,　and　over　a　WAN(66)impossible.　With　the　model　for　collaborative　work　spreading,　and　with　more　users　sharing(67)through　E-mail　and　the　Internet,　enterprise　EDM　had　become　a　necessity.Many　businesses　are　finding　their　greatest　competitive　advantage　is　the　ability　to　harness　the　document(68).　EDM　systems　manage　this　lifecycle　from　creation,　revision,　storage　and(69)to　routing　and　workflow.　They　also　allow　users　to　work　on　documents　collaboratively.Reusability　of　information　is　EDM's　main　benefit,　as　well　as　the　key　to　creating　the　paradigms　that　drive　business　process(70).
