The Wireless Dilemma
"The cautious seldom err." Confucius
"Be prepared." Robert Baden-Powell
To begin at the beginning is always a good place to start.
Let's begin with a shocking statement by a senior government
member of the Electronic Crimes Task Force, "Many businesses
should never have deployed a wireless network." He was
referring, of course, to the many security issues and problems
that wireless systems generate for his group. In addition to
security, there are many other items to consider before an
enterprise embarks on the path to wireless networks. During the
fuel rationing era of World War II countless bill boards
advised, "Is this trip really necessary?" The same question
should be asked before setting off on the wireless journey.
Wisdom dictates that we should begin with the end in mind. The
company must decide what benefits wireless networks will
provide. In some cases it will be legitimate: to increase
productivity, advance the speed of data and decisions for key
personnel, to empower mobile workers, or to garner cost savings
in replacing outdated system, etc. For others, it may simply be
the attraction of new gadgetry. A cost benefit analysis needs to
be made, as well as, deep level discussions and detailed
planning before these systems are approved and implemented.
Simple questions such as, "Is there an ROI?" and "When will ROI
be achieved, if ever?" also "Who will measure it?" These points
need to be explored. The most critical and over-arching question
that needs to be answered is a simple one, "Tell us again, 'Why
are we doing this?'"
Initial steps always involve basic fact gathering. Obviously,
common sense should prevail and stake holders consulted. End
users need to be interviewed and their needs and problems
studied and reviewed. Those involved in cost and technical
evaluations must communicate and work together to achieve the
common goal of determining if a wireless project is a sensible
undertaking. Do the end users really need it to address their
most important needs and to what degree will it actually matter
to the company's process and profit?
In the larger enterprise, there is also the "Silo Dilemma."
Whose ox is going to be gored? In other words, which
cost center
will ultimately bear the price? If the sales manager is
demanding a wireless system, should the IT department foot the
bill? These are issues that need frank discussion and
forethought and may require skilled diplomacy by senior
management.
In the smaller enterprise, the on-going cost of maintaining,
updating and monitoring the system and its users is often
woefully underestimated. Management in many companies, both
large and small, lack the understanding of the complexities
involved. The assumption is often made that implementing an
enterprise wireless network is somewhat akin to installing a
stereo system. Experience will quickly reveal that the reality
is very far from the case.
Before starting a wireless project some general requirements
should be determined. This would include factors such as the
system's security risks, the total cost of ownership, which
involves initial and recurring costs, ease of installation,
reliability, training expenses and scalability. This process
will lead to clearer results. Those involved in the deployment
decision can begin to see if the project is a worthy business
solution in light of its determined costs, training issues,
associated risks, and expected down time, etc. These issues are
especially pertinent to the smaller company which may have a
limited budget allocated for technology.
It cannot be stressed enough that deploying a wireless network
is a major project, especially for the smaller business. This
type of undertaking demands a dedicated effort, thoughtful
planning and committed leadership. Lacking accountability,
constant shepherding, and strong management support, the
wireless project will fit the profile of countless other
corporate "snafus" and missteps: over-budget, missed deadlines
and a half-baked dysfunctional outcome.
