"The only man who
behaved sensibly was my tailor; he took my measurement
anew every time he saw me, while all the rest went on
with their old measurements and expected them to fit
me." (George Bernard Shaw)
When implementing MRP at Federal-Mogul,
we discovered that our traditional operational
measurements would not help us transition to a leaner
environment. Measuring operational effectiveness by
machine usage doesn’t work in an MRP/JIT/Lean project.
Existing statistics were not producing the needed
results and in fact were leading to conflict and foot
dragging. By changing operational performance measures,
we were able to achieve the expected results but also
identify additional opportunities for improvement.
You’ve probably heard the statement “You
can’t improve what you can’t measure”. Taken on its face
value then, we couldn’t possibly make an improvement
without taking measurements. I guess whoever said this
was speaking in quantifiable terms that in order to
demonstrate that you actually have improved something,
you must compare two coordinates in order to prove that
you have moved from position A (previous situation) to
position B (current situation). However many times we
can tell we’ve improved by the reduction in “pain” we’ve
been experiencing. I guess my point is that don’t let
the inability to take measurements stop you from making
process improvements that you know need to be made!
You can walk around a factory and ask
anyone whether things are better as a result of an
improvement effort. They’ll tell you. It has something
to do with the “confusion factor” as referenced by Daryl
Landvater in one of the Oliver Wight education series
videos. No one really measures the confusion factor in a
company, but we all know its there. And sometimes it’s
worse than others. And if we achieve improvements many
times we can tell if the confusion factor has subsided,
without measuring it.
Measurements help define the “where
you’re at” and “where you’re going” coordinates when it
comes to the logistics of change. Measurements establish
the current condition and help establish goals or vision
of an improved process. When undertaking improvement
projects, take the time to really define what you’re
trying to accomplish. Don’t make statements that are too
general in nature, get down to the nitty gritty! The
devil is in the details!
For example, earlier this year, I worked
with a client to correct a chronic problem with the
behind schedule condition in their shear shop. Initial
measurements showed the workcenter dispatch list
contained 98 behind schedule orders, a current
situation. Here are some of the measurements that we
should have taken
1. The amount of time spent sorting
through a two foot stack of shop paper to determine what
to work next 2. The number of daily trips that the
supervisor had to make to the shear area to schedule
work 3. The number of jobs released late to the shear
After the improvement, I spoke to the
supervisor. Where he once was making 6-10 trips a day to
the shear area to schedule work, he now makes one or two
trips and some days he doesn’t make any! The shear
workcenter now runs with little scheduling supervision.
We also changed the process of releasing orders to
shear. Nothing is released to the shear more than one
week early and the shop dispatcher performs the closing
of the order release operation. This process improvement
identified that over 30% of jobs were released late. We
are now working to reduce late releases to operations …
the JIT journey continues!
With that said, let’s go about the
business of measuring some more quantifiable things:
Inventory accuracy, jobs behind schedule, BOM accuracy,
jobs released short of lead time, lead time accuracy.
These are more quantifiable. We can perform counts and
audits, take measurements and compare them as we
implement improvements over time. We can determine if
what we are doing is making a significant difference.
Measurements are great tools to
determine if process changes are producing the
improvements desired. Measurements can provide a great
deal of job satisfaction and enthusiasm for a project.
Make sure that you identify the detailed results that
you wish to accomplish and get your improvement project
started!
