What are the hidden costs of ERP?
Although
different companies will find different land mines in the budgeting
process, those who have implemented ERP packages agree that certain
costs are more commonly overlooked or underestimated than others.
Armed with insights from across the business, ERP pros vote the
following areas as most likely to result in budget
overrun.
- Training - Training is the
near-unanimous choice of experienced ERP implementers as the most
underestimated budget item. Training expenses are high because
workers almost invariably have to learn a new set of processes,
not just a new software interface. Worse, outside training
companies may not be able to help you. They are focused on telling
people how to use software, not on educating people about the
particular ways you do business. Prepare to develop a curriculum
yourself that identifies and explains the different business
processes that will be affected by the ERP system. One
enterprising CIO hired staff from a local business school to help
him develop and teach the ERP business-training course to
employees. Remember that with ERP, finance people will be using
the same software as warehouse people and they will both be
entering information that affects the other. To do this
accurately, they have to have a much broader understanding of how
others in the company do their jobs than they did before ERP came
along. Ultimately, it will be up to your IT and businesspeople to
provide that training. So take whatever you have budgeted for ERP
training and double or triple it up front. It will be the best ERP
investment you ever make.
- Integration and testing - Testing the links between ERP packages and
other corporate software links that have to be built on a
case-by-case basis is another often-underestimated cost. A typical
manufacturing company may have add-on applications from the
major?ae-commerce and supply chain?ato the minor?asales tax
computation and bar coding. All require integration links to ERP.
If you can buy add-ons from the ERP vendor that are
pre-integrated, you're better off. If you need to build the links
yourself, expect things to get ugly. As with training, testing ERP
integration has to be done from a process-oriented perspective.
Veterans recommend that instead of plugging in dummy data and
moving it from one application to the next, run a real purchase
order through the system, from order entry through shipping and
receipt of payment?athe whole order-to-cash banana?apreferably
with the participation of the employees who will eventually do
those jobs.
- Customization - Add-ons are only the
beginning of the integration costs of ERP. Much more costly, and
something to be avoided if at all possible, is actual
customization of the core ERP software itself. This happens when
the ERP software can't handle one of your business processes and
you decide to mess with the software to make it do what you want.
You're playing with fire. The customizations can affect every
module of the ERP system because they are all so tightly linked
together. Upgrading the ERP package?ano walk in the park under the
best of circumstances?abecomes a nightmare because you'll have to
do the customization all over again in the new version. Maybe it
will work, maybe it won't. No matter what, the vendor will not be
there to support you. You will have to hire extra staffers to do
the customization work, and keep them on for good to maintain it.
- Data conversion - It costs money to move corporate
information, such as customer and supplier records, product design
data and the like, from old systems to new ERP homes. Although few
CIOs will admit it, most data in most legacy systems is of little
use. Companies often deny their data is dirty until they actually
have to move it to the new client/server setups that popular ERP
packages require. Consequently, those companies are more likely to
underestimate the cost of the move. But even clean data may demand
some overhaul to match process modifications necessitated?aor
inspired?aby the ERP implementation.
- Data analysis - Often, the data from the ERP system must be
combined with data from external systems for analysis purposes.
Users with heavy analysis needs should include the cost of a data
warehouse in the ERP budget?aand they should expect to do quite a
bit of work to make it run smoothly. Users are in a pickle here:
Refreshing all the ERP data every day in a big corporate data
warehouse is difficult, and ERP systems do a poor job of
indicating which information has changed from day to day, making
selective warehouse updates tough. One expensive solution is
custom programming. The upshot is that the wise will check all
their data analysis needs before signing off on the budget.
- Consultants ad infinitum - When users fail to plan for disengagement,
consulting fees run wild. To avoid this, companies should identify
objectives for which its consulting partners must aim when
training internal staff. Include metrics in the consultants'
contract; for example, a specific number of the user company's
staff should be able to pass a project-management leadership
test?asimilar to what Big Five consultants have to pass to lead an
ERP engagement.
- Replacing your best and brightest - It is accepted wisdom that ERP
success depends on staffing the project with the best and
brightest from the business and IS divisions. The software is too
complex and the business changes too dramatic to trust the project
to just anyone. The bad news is a company must be prepared to
replace many of those people when the project is over. Though the
ERP market is not as hot as it once was, consultancies and other
companies that have lost their best people will be hounding yours
with higher salaries and bonus offers than you can afford?aor that
your HR policies permit. Huddle with HR early on to develop a
retention bonus program and create new salary strata for ERP
veterans. If you let them go, you'll wind up hiring them?aor
someone like them?aback as consultants for twice what you paid
them in salaries.
- Implementation teams can never stop -
Most companies intend to treat their ERP implementation as they
would any other software project. Once the software is installed,
they figure the team will be scuttled and everyone will go back to
his or her day job. But after ERP, you can't go home again. The
implementers are too valuable. Because they have worked intimately
with ERP, they know more about the sales process than the
salespeople and more about the manufacturing process than the
manufacturing people. Companies can't afford to send their project
people back into the business because there's so much to do after
the ERP software is installed. Just writing reports to pull
information out of the new ERP system will keep the project team
busy for a year at least. And it is in analysis?aand, one hopes,
insight?athat companies make their money back on an ERP
implementation. Unfortunately, few IS departments plan for the
frenzy of post-ERP installation activity, and fewer still build it
into their budgets when they start their ERP projects. Many are
forced to beg for more money and staff immediately after the
go-live date, long before the ERP project has demonstrated any
benefit.
- Waiting for ROI - One of the most misleading legacies of traditional
software project management is that the company expects to gain
value from the application as soon as it is installed, while the
project team expects a break and maybe a pat on the back. Neither
expectation applies to ERP. Most of the systems don't reveal their
value until after companies have had them running for some time
and can concentrate on making improvements in the business
processes that are affected by the system. And the project team is
not going to be rewarded until their efforts pay off.
- Post-ERP depression - ERP systems
often wreak cause havoc in the companies that install them. In a
recent Deloitte Consulting survey of 64 Fortune 500 companies, one
in four admitted that they suffered a drop in performance when
their ERP system went live. The true percentage is undoubtedly
much higher. The most common reason for the performance problems
is that everything looks and works differently from the way it did
before. When people can't do their jobs in the familiar way and
haven't yet mastered the new way, they panic, and the business
goes into spasms.
