that will sell TCONS to a project manager. That means that it needs to be less
than three minutes long verbally (including the 2 minute phone call interruption)
and must be no more than 2 A4 pages of printed matter of which at least one and
a half pages should be cartoons and words should be in 18 point text minimum. The
emphasis must be on how TCONS will make that project managers life more
endurable, which means that there is no real room for technical arguments, and
certainly no scope for a bitching session about TCP/IP. To do that you need to
try to feel the way that project manager feels.<o:p></o:p></span></font></p>
