Re: Business Case

Hi Barry,

  I suspect that the general lack of response to an excellent question
is more a common lack of production experience than a lack of interest.

  To my knowledge, in the US, significant bleeding edge production
deployments have all been to escape legacy centrex.  I think the
numbers for Jackson State are online somewhere.

  The speculative case depends greatly on whether you intend to
implement a POTS redesign or move to Integrated Communications.  In
the former it may be that there will be two major financial motives.
The first is whatever you think you can save by converging wires and
staffs.  The second is the substantial elimination of cost for 
moves, adds and changes.  I queried three Telecomm directors for
schools roughly comparable to Yale and their off-the-cuff response
was .5 - 1 million dollars/year.  Taking that with some fractional
co-efficient and then subtract whatever cost you may incur to upgrade
the underlying network to be able to carry real-time traffic.  You may
not save money at all but a stellar data network will fall out
of the effort.  One other value is that moves have no delay.  If you
implement DHCP, the user just unplugs her phone, carries it to the
new location and plugs it in - a nice service win.

  It's also worth noting that the funding model changes.  Rather than
needing some millions of dollars every 10-15 years, you'll need some
hundreds of thousands each year.  Again, the overall dollars may add
up to about the same, or even be more.  In a private institution this
may be an advantage.  If you need to go to a legislature for money it
could be a disadvantage.

  Integrated Communications relies far more on added value for its
case and we'd need to explore exactly what we mean by IC to be useful.
I included some of this in a presentation I gave a couple of weeks
ago at the VoIP workshop at TAMU.  Feel free to get my slides from
www.voice.yale.edu/deployment/TAMU_presentation.ppt if you like.  Also,
IU was represented.  I expect Mike could take some of these notions
and tweak them appropriately for IU.
