Uncovering the True Impact of SaaS
BY YOON-SUNG LEE, BOB FAHEY AND NAVIN MUKRAJ
COMPANIES LOOKING FOR WAYS TO SAVE ON LONG-TERM
costs often consider cloud services, specifically software as a
service. SaaS offers creative ways to address how companies
use technology, which lets them focus on what matters most:
their core business objectives. For IT organizations that deal
with complex, expensive maintenance chores, the SaaS model
promises to ease the burden and reduce costs and complexity.
Although SaaS sounds like an ideal technology solution, it is
not a cure-all for everything that ails IT, and it doesn’t always
make a significant impact on long-term costs and resource use.
That’s why it’s important for companies to consider a
wide range of variables when determining what the cost
savings from using SaaS might be, including hardware,
storage and management. At Avanade, we’ve developed
a cost-modeling tool that uses more than 120 real-world
variables to measure the true impact of one enterprise SaaS
offering—Microsoft’s Business Productivity Online Suite
(BPOS)—on capital expenses, operating costs, energy use
and carbon footprint.
IS SaaS THE RIGHT CHOICE?
The first step is for enterprises to determine whether SaaS or
other cloud-based solutions will serve their needs. To do that,
they should start by evaluating the potential business value
this approach can provide.
For example, take a look at the costs associated with
e-mail. This can include archiving, security, continuity, backup, policy management, maintenance, power and cooling,
hardware costs and regular upgrade costs. According to
Forrester research, the cost of e-mail for a 15,000-person
organization can be as high as $40 per user per month.
By using SaaS-based services, the burden of creating,
developing and sustaining the infrastructure is lifted from
the company. This frees up resources to focus on core
business objectives, and it reduces capital and operational
expenses for noncore tasks.
However, in addition to evaluating the potential benefits of
SaaS, companies should take the following steps before deciding to integrate a cloud-based service into their organization:
1. Investigate costs. Evaluate the costs associated with
internal IT versus the cost of cloud services. That analysis
will help determine what should be owned and managed
internally, and what could be cloud-ready.
2. Pursue a pilot. Start with a custom application that
leverages the instant scale, high-compute or bandwidth-intensive capabilities of cloud computing.
3. Communicate to your users. Make sure users are trained
on the new system and know whom to contact if there are
any issues. Communicating with employees is the biggest
item that companies underestimate. It’s important to be
as transparent and open as possible about the new system
and how to use it.
4. Consider a phased rollout. The more a business knows
about what it wants to do, the more likely it is that the
enterprise will be able to make the changes necessary to
accomplish its goals. By using a phased rollout, a company
can evaluate and make changes to the solution as it is
being deployed. This approach also allows the organization to achieve a few quick wins early in the process,
which helps build support for the system internally.
5. Don’t forget about the IT staff. Although moving to a
cloud-based solution removes a lot of the maintenance
and day-to-day technical aspects from the IT staff’s
responsibilities, companies still need to invest time in
training IT personnel on the new technology and new
skills relating to user management.
BASELINE JANUARY/FEBRUARY 2010
There are clear business benefits that can be derived from
SaaS and other cloud-based models. But there are no guarantees, so it’s essential that companies start with a clear plan,
sound analyses, and proven methodologies and practices. 3
