Poka-yoke
or mistake-proofing is using course of design
options to facilitate appropriate actions, forestall easy errors, or mitigate the
damaging influence of errors. It’s basically used to make the method simpler. To evaluate how efficient your answer
is, you have to take a look at three elements: the ability of the mistake-proofing answer,
whether or not it may be overridden, and whether it is sustainable over time.
The primary issue is to take a look at the mistake-proofing energy. The facility of
the mistake-proofing answer is a measure of how effectively the answer fulfills
the final word goal of mistake-proofing: to make it not possible to make
errors. There are three suggestions for bettering the ability of the answer:
- The primary tip focuses on the
set off of the answer. Utilizing an automated set off (pressured management
or shutdown) as a substitute of an operator dependent or discretionary one
(warning or sensory alert) improves the ability. - The second energy ranking tip focuses
on the kind of end result. The facility of the options with prevention
outcomes is considerably larger than these with detection outcomes.
When doable, deal with prevention, not detection, outcomes. - The third energy ranking tip entails
the kind of impact chosen. The facility of the mistake-proofing
answer turns into larger and larger as you progress up the results column.
Pressured management is normally higher than a shutdown impact, shutdown is
higher than warning, and warning is best than sensory alert.
The second
issue used to find out the effectiveness of a mistake-proofing answer is to
assess how effectively it’s defended in opposition to being overridden. Options may be
overridden if their set off may be ignored, if a tool may be disabled, or by
a malicious act.
The third and
remaining issue is to evaluate whether or not the answer is sustainable over time.
There are three questions to contemplate for assessing the sustainability of
the answer:
- Did the interim answer grow to be
“everlasting?” Many organizations fall into the entice of
permitting an interim answer to grow to be everlasting. Nevertheless, interim
options are like band-aids. They’re short-term fixes not meant
to be sturdy. To maintain interim measures from changing into everlasting
options, determine the obstacles for creating or implementing everlasting
options, develop a time-based plan, and comply with by way of. - Can practices regress again to the
“outdated methods?” Struggle off the urge to regress. To assist do
this, promote the advantages of the “new” means and audit efficiency
for compliance. - Are there service life points? Make
positive the suitable supplies are chosen. If shelf life is a priority,
use first-in, first-out stock management. Verify incessantly at first
to ensure the answer is working successfully and as deliberate. Then use
information to set the proper preventive upkeep frequency.
The
effectiveness of a poka-yoke needs to be judged after the efficiency of the
answer for a time frame. Ensure that the poka-yoke is supply the
outcomes you anticipate. If the answer shouldn’t be efficient, then attempt one other
answer by following the rules above.
