When
solving problems within operations, it’s possible to do so partially and to
have said problem manifest itself again and again with various mutations that
would make us think we’re dealing with multiple issues. By completely and
thoroughly resolving the core issue, we can accomplish two things: stop wasting
resources dealing with problems from the same core issue and create sustainable
improvement in the organization. In order to better solve problems, the
operations team should be well-trained and guided to find permanent corrective
actions for the problems they encounter.
1. Focus on Root Cause(s) and not Symptoms
It is very easy to focus on the symptoms that are most
visible in the organization when trying to improve performance. Unfortunately,
it’s not enough to scream “Stop being late with deliveries!” to resolve a
delivery problem -- if it were, every executive would at some point have
resolved the issue. Instead, we must ask “Why?” and drill down until the core root
causes are identified. There can be one, multiple or interrelated root causes
to any particular issue that manifest themselves in the operation.
2. Turn-off All Root Causes
If we only defeat one root cause of a problem that has
multiple causes, the problem will re-establish itself shortly and perhaps
change slightly so as to be considered a new or different problem. When we
conduct our root cause analysis, we should identify all root causes and develop
plans to turn off each one (or one of any given interrelated grouping) to make
sure the problem never recurs.
3. Don’t Mistake Containment for Resolution
As soon as an operational problem is discerned, it
should be contained. Awareness should be raised and those affected should work
together to identify a short-term strategy for making sure the problem doesn’t
escape the immediate area while permanent corrective actions are developed and
verified. All too often, this temporary action can remain in place far too long
while other more emergent issues are looked after. Instead, be certain to use
the containment action to stop problems from becoming tragedies, but don’t
allow containment to remain past its welcome.
4. Audit Results of Problem-Solving
When a problem has been certified as “solved” within
the operation, this should trigger periodic and scheduled assessment of
resolution to ensure that it is truly fixed. A post-mortem should also be
conducted to understand why the things that functioned properly were effective
and why failures were ineffective. Brutal honesty and focus on process are
essential to be effective in this endeavor.
5. Don’t Over-Adjust
It can be a tendency of executives driving
problem-solving activity to make immediate adjustments when they learn that,
after a process has been changed to solve a problem, the problem re-emerges.
Remember that occasionally the cycle-time to incorporate solutions is longer
than the frequency of emergence. This means that, while the problem is being
solved and the process modified, other problems may occur that escape the
containment strategy -- particularly if all root causes are not yet understood.
In this case, it is important to identify which problem manifestations occurred
because of failed containment and which occurred because the new process is
still faulty. Focus on root cause of the failure here is essential for final
resolution.
By carefully solving the problems within our
operation, we can consistently increase profitability and create more output
with fewer resources. It’s essential to do a great job of problem
solving -- every time!
