Setting up an intranet or extranet can be as
easy as purchasing access through an application service
provider (ASP), purchasing and installing third-party software,
or building an extranet or intranet internally.
Here is a quick summary of the advantages and disadvantages of
each approach:
1. Building it yourself Advantages: Complete
control of user interface design; ability to customize level of
functionality for each client; integration into internal
systems, and direct access to user activity.
Disadvantages: High up-front development cost; requires
staff expertise in the development of intranets and extranets,
commitment of internal staff for 6 months to a year for
planning, execution, review and implementation; and an ongoing
commitment of internal staff for internal and client support,
hosting, maintenance and upgrades.
2. Purchasing/installing third-party software
Advantages: Proven track-record of packaged solution;
ability to choose functions and to customize user interface,
more rapid implementation compared to building it yourself.
Disadvantages: High up-front purchase cost; commitment of
internal staff for customization and implementation; on-going
commitment of internal staff for internal and client support,
hosting, maintenance and upgrades; and extensive internal and
client training.
3. Using a Service Provider (ASP) Advantages:
Proven track-record, often with expertise in the application of
intranets and extranets in particular industries; low cost of
entry and predictable cost over time; virtually immediate
implementation; no commitment of internal staff for internal and
client support, hosting, or maintenance; and upgrades at no cost
by extranet experts, and savings on internal server use.
Disadvantages: Less freedom in user interface design, and
fixed functionality.
In the final analysis... The approach you choose depends
on how you work, the technical and financial resources at your
disposal, and how rapidly you need to move forward.
