Do your processes speak or are they too shy to bring problems to your
attention? When it comes to the workplace, you want processes to be as
loud and obnoxious as possible when something isn’t running exactly as
planned.
Moving toward lean thinking often requires
transformation. This means a significant shift in thinking, leading,
systems, and general approach to operating the business. Although there
are elements that are common to most transformation efforts,
organizational differences make it difficult to single out one or two
that apply in all circumstances. One of the most common but often
overlooked elements involves making the workplace speak.
Processes
must be designed so they sing out when problems occur enabling issues
to be identified and addressed quickly. Without the ability to speak, a
process can hide problems until they become such a normal part of the
operation that they are no longer recognized as problems. When this
happens, the process moves further away from the ideal state and
countermeasures, when applied, consist of throwing money at symptoms.
Examples include increasing inventory, lot sizes, and inspection – all
of which increase costs while giving a false sense of security that a
problem is effectively addressed.
Clarifying Objectives
Clarity
of objectives is the foundation for encouraging processes to speak. When
objectives are clear, it becomes much easier to create signals that
communicate problems immediately when something puts an objective in
jeopardy. Examples include takt time, inventory levels, and problem
boards.
Takt Time
If
we can identify the optimal pace for a process and focus attention on
maintaining that pace, setting up a signal that identifies when a
problem occurs should be fairly easy. This can consist of a takt board
or dashboard that shows when a process step is unable to keep up with
the rest of the process.
Inventory Levels
Setting
up visual cues regarding inventory levels can make it obvious when a
process is overproducing. As an example, installing a bin system
between two processes that only holds a maximum or minimum number of
parts will signal when the prior process is producing faster or slower
than the following process. Whether the problem lies with one area
overproducing or another failing to keep pace will not necessarily be
known, but it will be clear that something is wrong.
Problem Boards
Making
the process speak can be done as easily as setting up a board in the
workplace where problems can be recorded as they occur. Parts that
don’t fit properly, instructions that aren’t clear, or equipment
breakdowns can be easily recorded using a checksheet, free text, or both
to bring problems to the attention of those who are able to address
them. Without an easy way to record these types of issues, however,
they can continue to occur due to a lack of visibility.
Andon
A common signal used in assembly lines is the andon cord, which is pulled by workers whenever something interferes with doing their work as planned. Even without an assembly line, however, the andon concept can be used by providing people with the ability to signal when a problem occurs. Whether it's an audible alarm in the factory, a signal light that goes off in an office, or a text message that is automatically transmitted to those who need to know, the andon can be a valuable way for the process to speak.
Make the Workplace Scream
Very
few of us like to work with people who are loud and obnoxious, yet
these are the exact traits we should desire in our processes. Processes
should be designed in a way that they scream so loudly when a problem
occurs that we never feel it is acceptable to let them go on for very
long. The workplace should be quiet only when things are running
smoothly and all objectives are being met.
