Challenges
in Calculating ROI
By Bob
Kasper
The concept is simple, the calculation is difficult. At first glance, the equation seems easy:
ROI = decreased
expenses + increased revenue
project costs
The
difficulty starts in calculating the first component, and gets harder when
calculating the second. Components of
decreased expenses include the amount of time employees must spend in the
future due to perform tasks associated with improved processes. The amount of time saved can be difficult to
pinpoint. Most traditional approaches
profile current activity levels and forecast future levels. In fact, many post-implementation studies
have failed to establish savings from reduced labor unless a staff reduction is
attached to the system. Unless
specific work is done to redirect labor released by a new system, the benefits
will not be recaptured. Any ROI
calculation must include the effort to capitalize upon these increased
efficiencies.
Additionally,
the value of time saved can become arbitrary based on the formula used. For a starting point, the employee’s salary
is an easy way to measure savings, but one should also include direct employee
“overhead” costs, such as benefits, including all insurance costs, retirement
plans, and all other employee benefits.
Many companies approximate these benefits to be 32-35% of an employee’s
salary. This overhead can be extended
further to include office space, computer-related expenses, and other less
tangible costs. But without a full
survey of each savings item, this calculation may be misleading. Many overhead costs may be relatively fixed
and will not be changed by minor staff reductions.
Before
approaching an ROI, it is important to get clear agreement with program sponsors
on which components of cost savings that will be considered legitimate. Agreement on the calculation and relative
balance will ease gaining sponsorship.
A blanket requirement for ROI can only be accommodated by a thoughtful
step-by-step approach to the unique factors in each program or project. In addition to labor savings, other factors
for savings should be considered.
Outside assistance in establishing correct values and equivalents can
provide authority to an impartial ROI calculation.
Justifying
a project on increased revenue is also difficult to calculate. The process itself is an estimate based on
different variables, each of which can also be an estimate. A variation on this calculation occurs when
a company decides to do a project not to increase revenue but rather to try and
stave off revenue loss due to
competition. Trying to calculate that
component is another foray into guesstimation.
For the
rest of the calculation, project cost is probably the easiest component to
determine, but there are pitfalls in this calculation as well. Employee costs again factor into this value,
but not only for the reasons listed above.
When determining the labor cost of a project, one key element is the
percentage of time each employee spends on the project. Even employees who are 100% dedicated to a
project are not truly spending all of their time on project-related
activities. Staff meetings, personal
email, and other non-productive time must be factored in.
Finally,
depending on the project’s objectives, there are other factors that may come
into play. For example, one objective
of many projects is “increased customer satisfaction”. The individual amount of improved customer
satisfaction that a single project brings to a company can be next to
impossible to calculate in the first place.
Determining a monetary value to this increase can be even more
difficult. Also, the risk of not
doing a project is sometimes overlooked.
The failure of a company to keep up with its competition is detrimental
at best, and potentially devastating in the long-term.
All this
being said, calculating a project ROI is a worthwhile exercise. All projects should be held accountable, and
creating specific metrics is Project Management must. Those performing the ROI calculations must simply understand that
their numbers must be defensible, but will not be definitive.
