Six Sigma and Lean have gotten a lot of headlines in the legal
world as a result of Seyfarth Shaw’s highly publicized success in using them to
streamline work. Both approaches originated in the world of manufacturing, and
are examples of process improvement techniques which redesign the way work is
performed to increase value and efficiency.
However, there has also been an enormous amount of confusion
over exactly what these approaches require, and how they are related to each
other, and to legal project management (LPM).
I became aware of the seriousness of this problem a few years
ago when the Director of Professional Development at an AmLaw 100 firm asked me to explain the differences
between project management, process improvement, Six Sigma, and Lean. This was
an extremely sophisticated client who had been researching this area for
months, but she had heard so many different claims from competing consultants that
she had trouble keeping them straight.
I explained that Six Sigma is built around techniques Motorola
developed to eliminate the causes of manufacturing defects and errors. Lean was
developed by Toyota to increase manufacturing efficiency by eliminating the
“seven wastes” (excess inventory, excess processing, overproduction,
transportation, motion, waiting and defects). They are just two examples of a long
list of process improvement methodologies used in other businesses, including
business process re-engineering, total quality management (TQM) and ISO 9000.
In my new book, I explain how experts are still arguing about the definition of LPM, and we
believe that there are many reasons to use this broad definition: “LPM adapts proven management techniques to the legal profession to
help lawyers achieve their business goals, including increasing client value
and protecting profitability.” Thus,
we see LPM as an umbrella term that embraces a very wide range of management
techniques. If a proven technique can help lawyers accomplish their goals, we
say it is part of LPM.
If you accept this definition, process improvement, Six Sigma,
and Lean are specialized approaches that fall under the more general umbrella
term LPM. They are simply tools in the belt, to be used in some cases and
ignored in others.
Others disagree and argue that process improvement is separate
from LPM, and must come first. As one consulting company warns on their web
page, “You can manage to perfection, produce exactly what you promised for your
client, achieve each milestone on time and demonstrate excellence every step of
the way. But what if you’re managing an inefficient process?… Legal project
management doesn’t look at the efficiency of the steps in the project itself.
What if you could get from A to B in fewer steps, in less time, with less
waste, or by spending less money? Once you’re thinking like this, you’re
thinking about process improvement.”
To date, only a few law firms have accepted the purist approach
of focusing on process improvement before they implement other simpler and
cheaper LPM tactics. Of the 108 law firms that responded to an ALM survey on
LPM, only four said that they had
worked with an approach “modeled after Six Sigma (e.g. Seyfarth’s Lean Sigma).”
This is not surprising, given that Seyfarth spent several
million dollars and more than five years on this approach.
One reason process improvement requires so much effort is that
you not only have to figure out how things should be changed in the ideal world,
you also have to get lawyers to accept the new process and change their
behavior. (For examples of an alternative approach to behavior change, download
the free preview chapter from my book.)
It is human nature to want to do things your own way, and
behavior change is a challenge in every profession. According to Carl Binder of The Performance Thinking Network, business
process consultants often identify better ways to perform work but then they “can’t
get the damned people to execute the process.” This is especially challenging
in law firms, since compliance must sometimes be enforced by a powerful central
management team, and many law firms don’t have a powerful central management
team.
Process improvement clearly has a place in re-engineering the
way some legal services are delivered, some of the time. It will be especially useful
for the types of legal work that include “cookie cutter” steps. A careful
examination of the steps in a repetitive work process can reveal opportunities
to streamline and increase efficiency.
For example, when Morgan Lewis used process improvement analysis to improve
the delivery of mortgage services, they began by identifying
defects in the process that did not add value to the client, including
excessive staffing, excessive drafting, and internal meetings. Then they analyzed the causes of these defects, and traced some of the problems
back to poor data input, lack of standard high quality forms, lack of associate
training, and disorganization related to time pressures. Finally, they
developed a number of solutions including standard forms, standard operating
procedures and standard communication procedures. These changes enabled Morgan
Lewis to reduce the cost of delivering mortgage
services “often by more than 25%.”
But that does not mean that process improvement is the best
approach for every problem, and it does not mean that it must come before other
LPM tactics. Arguing that you must fundamentally improve a process before you
start to manage it is a little like saying that if you have a car that needs a
paint job, you shouldn’t bother washing it. It’s a great example of the adage
“perfect is the enemy of good.”
If a law firm has the time, the money, and the will to change
the fundamental way they provide services, process improvement will certainly
allow them to deliver more value. The question is: do you think that process
improvement is the best way to deliver value in a particular situation?
