LANCOSTS.WK1 Notes
Revised 2/92

The LANCOSTS.WK1 models facility server and work group server LAN
costs.  The model was written using 1-2-3 v2.3.  Although it might
work without error, it has not been tested using other spreadsheet
versions.

Although real situations were used as the basis for this model, the
author can not assure that the assumptions made will be applicable
to all situations.  Use this model only as an approximation.  Your
reality may vary.

Various items require user input to reflect an organization's
particular perspective.  Calculated fields have been protected to
prevent unintentional erasure.

Comments are welcome for improving this model.

Categories and descriptions of user defined fields include:

Section 1.          Assumptions

# of Users          Total number of LAN users within the
                    organization.

Users Per Server    Average estimate of users defined to each
                    server.  Note, Defined not concurrent usage.

% Overage To        This value describes when additional users
Justify New         are added to existing servers and when new
Server              new servers are procured.  This value is the
                    users, above the average users per server
                    required to procure a new server.  If average
                    users = 350, and overage = 20%, then a new
                    server is assumed when there are greater than
                    20% or 71 persons requiring LAN services.  An
                    organization of 1400 people would require 4
                    servers.  1471 persons would require 5 servers
                    under this scenario.

Server/Corp.        An assumption is made that there will be both
Consultant Ratio    key senior strategists/consultants and LAN
                    Managers to run the network.  This ratio sets
                    the number of senior strategists/consultants. 
                    Formulas have been set to assume that more
                    than half of the ratio of servers to
                    consultants will be required before a new
                    person is added.  In all cases, a minimum of 1
                    person is assumed in this category.

LAN Personnel       These values describe the LAN Managers
                    required to run the enterprise LANs.  Dollar
                    values are asked for Principal, Senior and
                    Entry positions.  A mix is entered to model
                    the experience levels of the LAN personnel.  A
                    mix adding up to 100% would assume 1 LAN
                    Manager per server.  A mix of 0 would assume
                    no LAN Managers. A Mix of greater than 100%
                    would assume more than 1 LAN Manager per
                    server.  It should be noted, that the facility
                    server mix does not (and most likely will not)
                    be the same as the numbers entered for the
                    smaller and less complex work group server
                    scenario.  


Section 2.          Facility/Work Group Server Investment

Cost Per Server     Cost of hardware including backup unit(s).

Operating System    Cost of NetWare 386 or other LAN Operating
                    system software.

Section 3.          Other Significant LAN Investment

Ave. Cost Per       
Printer   

Average Users Per
Printer

Ave. Cabling Cost
Per Node

Section 4.          Facility/Work Group Server Recurring Costs

Maintenance Rates   Enter Facility server (hardware/software,
                    printer and software/upgrades maintenance
                    rates.  All do not have to be the same.  A 0%
                    value may be entered in any of these
                    categories.

Section 5.          Education and Training

CNE Training Rate   Your cost for CNE training courses.

Supervisory         You costs for NetWare 386 supervisor training
Training Rate       or equivalent if alternate operating systems
                    are in use.
