In-House Deployment Versus
Outsourced Deployment
One of the first decisions you must make before proceeding with
a deployment is whether to use your own internal IT resources or to outsource the deployment to a skilled
and experienced vendor. In many
circumstances, and depending upon the scale of the deployment, you may end up
doing a combination of both. Some of the factors that may help you make this
decision are listed in the next sections.
Internal Staff
Advantages to using internal staff for your deployment include
the following:
-
It is potentially cheaper for small- to medium-sized
deployments.
-
Your IT team can increase their wireless skills.
-
Your staff has end-to-end visibility and familiarity with the
solution, as opposed to your team taking ownership of a "fully baked" WLAN
solution that was designed and deployed by third parties.
-
You avoid potential security concerns associated with engaging
external vendors to work on your enterprise network.
Conversely, utilizing limited internal resources also has
several disadvantages. These include but are not limited to the following:
-
Deployment may take longer due to resource constraints.
-
Your staff may make common mistakes and encounter challenges
that an experienced solutions provider would avoid.
-
Your IT department may not already have wireless skills and
experience.
-
Your IT department may not have the required equipment on
hand.
-
Your staff will have ongoing responsibilities and possibly
other projects to complete.
Outsourced Resources
An alternative strategy to using internal resources is to
retain outside help. Many large enterprises choose to engage an outside vendor
either for the complete deployment or to provide additional resources for the
implementation phase.
Some advantages of using external vendors include the
following:
-
They will be wireless experts and potentially have certified
wireless engineers.
-
The vendor may have national or international presence in
locations to which your staff would otherwise have to travel.
-
The vendor will have extensive experience, often with
deployments very similar to yours.
-
They will not need as much time to "ramp up" and commence the
installation.
-
They will usually provide dedicated project management
capabilities.
-
The vendor can work to an agreed Service Level Agreement (SLA),
often with penalty clauses for project delays.
Following are several of the disadvantages:
-
The cost involved may be higher.
-
Introducing a third party into the deployment creates
management and administrative overhead.
-
Permitting a third party access to your network might raise
security concerns.
Of course, many of these disadvantages associated with using
external resources, can be mitigated. For example, additional cost of using
external resources may be offset by the savings you make by utilizing the
vendor's local presence in a large national or international deployment. The
time spent to develop and increase the wireless skills of your internal staff
may pay dividends later with improved troubleshooting and technical abilities
in-house. Security concerns with using external vendors for sensitive network
infrastructure projects can be mitigated or entirely addressed by careful
management. Carefully consider whether to use in-house or outsourced resources
before you start. Many internally resourced deployments have encountered
problems only to resort to calling in assistance later, while some outsourced
projects have had costs spiral out of control. If you have tasked a program
management office (PMO) with the implementation of the WLAN, ensure that the PMO
carefully monitors and manages relationships with external vendors, and ensures
smooth workflow between all stakeholders and teams.
