Case Study III-2 • A Make-or-Buy Decision at Baxter Manufacturing Company 447

He may or may not make the changes that you want,
and in fact he may make some changes that you do not
want. If you do not expect the system to change and it
is a common system, you probably should purchase it.
For example, one general ledger system is just like
any other, and they haven’t changed in 20 years, so
you should purchase this application. But we are
continually changing things out in the shop, and if we
build our own systems, we can change them when
we need to.
Finally, we have demonstrated that we can
build and successfully install our own systems, but
our record with purchasing and installing manufac-
turing systems is dismal. The EMS proposal may
fulfill our needs, but then again it may not. We failed
twice in the past because the system we purchased
did not fit our needs. Why take that chance again?

“You seem very concerned that the EMS system
might not suit our needs or that our needs might change,”
Baxter replied. “Could we modify this system if it does not
suit our needs?” Collins said:

Because we will not have a source-code version of
the software, it will not be feasible for our program-
mers to modify the functionality of this system.
However, we can write interface software to change
the form of the system’s input and output.

When Baxter noted the cost and time differences
between purchasing and building the system as estimated
by Moore, Collins replied:

The figures Lucas quotes are very misleading. The
purchase price is but a part of the total cost of buy-
ing, installing, and maintaining the software. To be
sure you are choosing software that truly meets your
needs, you must put a substantial effort into defining
your needs and evaluating each candidate package
against those needs. One of the major weaknesses of
the present proposal is that this process of defining
needs and evaluating possible packages has been
completely ignored. In my opinion we must go
through this process before buying any packaged
software, and this will affect both the proposed cost
and how long it will take to install the system.
Another cost of purchasing a system is the
cost of modifying your existing systems so that they
can feed data to or receive data from the purchased
package. If the systems that must be interfaced with
the purchased systems are also purchased systems
that you cannot modify, you may have to create

in our factory so we can devote our energy to making
the new system successful.

Collins’ Views


Baxter also talked with Collins, who argued that BMC
should continue its process of building the manufacturing
systems that it needed. He estimated that the needed sys-
tems could be completed in about two years at a cost of
around $420,000—$220,000 for outside help (including
training his people in new development tools) and
$200,000 in internal costs.
When Baxter asked Collins why BMC should not
purchase the EMS software, Collins replied:


First, the EMS software is far more complicated than
we need. For most general manufacturers each part
may require six operations on six different types of
machines, and each part has a routing that is differ-
ent than other parts. Then several parts may be
assembled into a subassembly, so you have two- or
three-level bills of material. We typically take a coil
of steel, stamp out the part, clean it, box it, and ship
it out, so both our routings and our bills of material
are very simple, as is our production process. The
EMS system is designed for much more complex
manufacturing.
Second, we have had little or no experience
with computerized production systems. Does it
make sense for us to try to jump to a very complex
and sophisticated system like the EMS proposal?
Lucas has a very superficial understanding of this
software package, and he doesn’t know any of the
details of how it will work. Therefore, he has no idea
of the difficulties that his people will run into in
adapting to this complex package. It will require
them to do many tasks that they have never done, or
even considered doing. And they don’t need this
complexity. Wouldn’t it be better to build our own
systems that correspond to where we are on the
learning curve and plan to upgrade them as we
progress in our understanding of our systems needs?
Third, it is likely that the system does not fit
the way we are running the business. Do we change
the system or do we change how we run our busi-
ness? We probably can’t change a purchased system,
so we would have to change the way we run the busi-
ness. Do we really want to do this?
Fourth, we are constantly changing our manu-
facturing facilities and processes, and they may be
unique to our business. If you purchase a package, you
are at the mercy of the vendor to make changes in it.
