In my last blog I told you not to just jump
right into the UIC and begin the improvement process. In this blog posting I’m
going to give you 10 prerequisite beliefs that your organization must embrace
before your organization will be able to successfully implement and navigate
through the Ultimate Improvement Cycle:
1. Believing that leveraging the constraint
and focusing your resources on the constraint is the key to improved
profitability. Because of this, the constraint can never sit idle.
2. Believing that it is imperative to
subordinate all non-constraints to the constraint. If you violate this key
belief, your throughput will not improve and your WIP will grow to unacceptable
levels thus draining cash from your coffers.
3. Believing that improving your process is a
never-ending cycle. You must be ready to re-focus your resources when the
constraint moves and it will move eventually.
4. Believing that involving and empowering
your total workforce is critical to success. Your work force has the answers if
you will first listen to what they have to say and then engage them to design
the solution.
5. Believing that abandoning outdated
performance metrics like efficiency and utilization, reward or incentive
programs, and variances is essential to moving forward. As Goldratt says in his
book, The Goal, “Show me how you measure me and I’ll show you how I’ll behave.”
These outdated metrics and practices are archaic tools from the past….so let
them go.
6. Believing that excessive waste is in your
process and that it must be removed. Studies have confirmed that typical
processes have less than 10% value-added work meaning that waste accounts for
90% of the available time.
7. Believing that excessive variation is in
your process and that it must be reduced. One of the keys to growth in
profitability is consistent and reliable processes. Processes are full of variation
and uncertainty and unless and until variation is reduced, moving forward will
be difficult.
8. Believing that problems and conflicts must
be addressed and solved. You can no longer afford to hide problems with
inventory. When problems arise, you must stop the process and take the time to
solve them. By solving them, I’m talking about finding and eliminating the root
cause(s).
9. Believing that constraints can be internal,
external, physical or policy or any combination of the four. In the real world,
over 90% of all constraints are policy related. Policies and procedures must be
scrutinized, changed and sometimes thrown in the garbage and replaced with
policies that make sense.
10. Believing that the organization is a chain
of dependent functions and that systems thinking must replace individual
thinking. It is no longer acceptable to focus on improving single steps in the
process if it isn’t the weakest link. This focus on local optima must be
replaced with system optimization.
If your entire operation is able to accept the
prerequisite beliefs of constraint focus and leverage, then you have taken the
first step, but it must include everyone….and every department. Your entire
organization must become focused on the leveraging power of the constraining
operation. If you can’t do that, then there simply is no need to continue.
Unless and until all functional groups within your organization are singing
from the same sheet of music, you simply will not make any progress.
Of all the TOC focusing steps, subordination
will be the most difficult one to apply. It simply means that every decision
made and every action taken by the entire organization must be done so based on
its impact on the constraining resource. And when I say the entire organization,
I mean everyone!
Accounting must provide real time
decision-making information to the organization and not hold onto financial
measures that are based on what happened last month. Accounting must also
eliminate outdated performance metrics like utilization and efficiency in
non-constraint operations because they mean absolutely nothing. Purchasing must
order parts and materials based upon the rate of consumption at the constraint
and stop ordering in large quantities or only on the basis of lowest cost to
satisfy another outdated performance metric, purchase price variance. Sales and
Marketing must understand that unless and until the current constraint is
broken, they must not make hollow promises on delivery dates in order to obtain
more orders to supplement their sales commissions. Engineering must respond
quickly to the needs of production to assure timely delivery and updates to
specifications. Maintenance must always prioritize their work based upon the
needs of the constraining operation including preventive and reactive
maintenance activities. If there is an inspection station that impacts the
constraint throughput, then inspectors (if they exist) must always provide
timely and accurate inspections so as to never cause delays that negatively
impact the flow of materials into and out of the constraint. Finally,
Production Control must stop scheduling the plant on forecasts that we know are
wrong using the outdated algorithms contained within the MRP system.
As you identify the constraint and subordinate
the rest of the organization to the constraint, there will be idle time at the
non-constraints. If you are like many organizations that use total system
efficiency and utilization as key performance metrics, then you will see both
of them predictably decline. You are normally trying to drive efficiencies and
utilizations higher and higher at each of the individual operations under the
mistaken assumption that the total efficiency of the system is sum of the
individual efficiencies. In a TOC environment the only efficiencies or
utilizations that really matter are those measured in the constraint operation.
You may even be using work piece incentives in an effort to get your operators
to produce more and I’m sure many of you are using variances as a key performance
metric. Efficiencies, utilizations, incentives and variances are all
counterproductive!
Believe me, no matter how good you think your
processes are, they are full of waste and variation. You must accept the
premise that every process contains both excessive amounts of waste and
variation that are waiting to be identified, removed, and reduced. Your job
will be to locate, reduce and hopefully eliminate the major sources of both.
Variation corrupts a process, rendering it inconsistent and unpredictable.
Without consistency and control you will not be able to plan and deliver
products to your customers in the time frame you have promised. Waste drives up
both operating expense and inventory, so improvements in both of these go
directly to the bottom line as you improve the throughput of your process and
more specifically your constraining operation. Yes, you will observe waste in
your non-constraint operations, but for now focus your resources only on the
constraint!
If your organization has truly accepted these
ten prerequisite beliefs and all that goes with them, then you are ready to
begin this exiting journey that has no destination. But simply saying you
believe something can be hollow and empty. It is your day-to-day actions that
matter most. Review these ten prerequisite beliefs as a group on a regular
basis and hold people and yourself accountable to them. Post them for everyone
to see. Utilizing the Ultimate Improvement Cycle and true acceptance of and
employment of these ten beliefs will set the stage for levels of success you
never believed were possible!
