Confidence –The
Magical Element of Cross Functional Teams
by
Winston Ledet,
The
Manufacturing Game
In the thirteen
years we have offered The Manufacturing Game® to over 32,000
participants, I have always marveled at the accomplishments of
small cross functional teams and wondered what determines the
great results they achieve. I have often sat with teams as they
attempted to come up with a plan to eliminate a defect they
identified as their target. From the rational point of view of
an engineer, it appears that they will never arrive at a
solution. Then someone comes up with an insight that immediately
resolves the problem; the plan to eliminate that defect is then
completed via some simple action or actions. Where did that come
from? This is the phenomenon that we recognize as the magic in
cross functional teams. But how does it come about?
An example, from a
DuPont Chemical site was a team working on extending pump life
in an ethylene plant. As it turned out, the biggest offenders
were brand new pumps installed in benzene service. The pumps
were totally enclosed without seals to avoid any leakage of
benzene to the atmosphere. Consequently, the bearings in the
pump were exposed to the benzene flow. Since benzene is a great
solvent, it quickly washed all of the lubricant out of the
bearings, causing them to fail. The team was stuck with a
dilemma. If they used the seal less pumps, the bearings failed.
If they used a pump with seals, some toxic benzene escaped into
the air. This was the proverbial "between a rock and a hard
place." After about 30 minutes of discussing alternatives, an
operator said "Wait a minute; I think there is enough upstream
pressure to move the benzene through this unit without a pump."
Removing and disposing of the brand new pumps solved the
problem.
Another example of
the "magical" accomplishments of cross functional teams comes
from what was a well known problem at the former BP refinery in
Lima, Ohio. The butane sphere was overheating in the summer
months, and periodically butane had to be vented to the flare to
relieve the pressure. This problem was already on a list of
projects to be addressed by engineering with the approximate
cost of $400,000. At a Manufacturing Game workshop, a cross
functional team composed of people from operations and
maintenance decided to work on this problem. They felt that the
overheating compressor was a safety hazard in the summer months.
Once the team started working on this defect they quickly
determined that the cooler on the compressor was undersized; it
was very hot to the touch. They recruited an engineer to be on
the team to check the specifications on a substitute cooler.
They had it refurbished and sent it on to engineering to ensure
it passed through their management of change process for safety.
The new cooler was installed and immediately the pressure on the
vessel came down and the valve to the flare could be closed. The
total cost for this improvement was $5,000. The team eliminated
the safety issue and in the process cut out over $1.5 million
worth of butane going to the flare annually. They also
eliminated the need for engineering to address this problem for
$400,000.
There are many
examples where spontaneous ideas occur that cannot be explained
in the cause and effect world of engineers. Over the years we
have tried various methods to make the Action Team process more
rational, but our efforts have not been as effective as we had
hoped. To facilitate forming Action Teams, we developed a
booklet that we believed would put order to the process, but
over time we decided that it really didn't seem to be helpful.
Our facilitators, as well as some of the engineers at our client
sites, liked the booklet. We had to admit to ourselves, however,
that even though it made the process more organized, it didn't
seem to help with the quality of the teams or the results that
they achieved. The best criteria for predicting success of
Action Teams is still determined by how much the people on the
team care about a piece of equipment that needs improvement and
how well all of the functions are represented on the team.
I recently ran
across an explanation by John Bennett that makes sense to me.
John Bennett wrote books on the role of human beings in the
universe. His view is that creativity is a gift that human
beings receive when conditions are right. My understanding of
these conditions involves four aspects. First, people have to
possess certain skills and knowledge to help them recognize the
details of the situation. Second, people have to have enough
discipline in their work habits so they are not introducing
extraneous variations into the situation. Third, people need a
framework that helps them recognize the essence of the
situation. Finally, people need to have the confidence that they
have the first three aspects fully covered. It is this
confidence that I think is the magic of cross functional teams.
Bennett says, "Confidence is the element that creates the
opportunity for something creative to happen spontaneously." My
father-in-law, who was a successful businessman, always said he
liked the "confidence" aspect of doing business. As an engineer,
I always struggled to understand what he meant by "confidence"
but now I think Bennett's explanation gives me a better
understanding of the concept.
So how does
confidence get created in a cross functional team? To paraphrase
J.G. Bennett from a book he wrote in 1964, creative thinking
happens when people are sure they have exhausted all the
possibilities. Only then, do they come to have the answer. By
having a cross functional team of people, who have intimate
contact with the equipment in question; involved in a discussion
about a problem they care about, it usually doesn't take very
long to exhaust all the possibilities for a solution, or in
fact, find a solution within existing knowledge. When the team
thinks it cannot find an existing solution, and they think all
possibilities have been exhausted, the magic can happen. When
people start to think "outside the box" and new innovative ideas
start to flow "The Confidence of Cross Functional Thinking"
begins to happen.
