In order to truly make process improvements,
you must investigate, take action, and document
when nonconformities or non-normal variation
are detected in your processes. A key element
in achieving this operational excellence is
to identify the sources of variation that affect
your process, product or service. Once identified,
these key sources can then be earmarked for
attention.
The road to process improvement is achieved
through production visibility and the implementation
of a more immediate and interactive Statistical
Process Control (SPC) system. Statit
e-QC is a web-based SPC application that
allows the user, in real-time, to earmark any
special cause variation that may have
some assignable cause, as well as document
and track changes made to a process. Instead
of having control plans displayed on paper process
sheets out on the floor, users can enforce and
analyze these changes through Statit e-QC. Statit
e-QC's browser interface, allows users to click
on SPC violations and interactively enter the
relevant information.
The example below is a report from our online
Statit
e-QC demo site. This particular report allows
the user to perform two very important actions.
When the user clicks on the data point "in
question", they are provided with the data
entry window that allows them to tag that point
as an assignable cause and to document any changes
to the process.
Example 1
Let's now take a look at the assignable cause
feature. Example 2 below shows our control chart
after we've tagged the point as an assignable
cause and added our comment as to the reason
for the excessive variation. In our example
here, one of the parts was deficient, "O
Ring Bad". You'll notice two key changes
to our chart. One, the point has been flagged
with a red check mark signifying that there
is an assignable cause and two, that point was
taken out of the calculations of the control
limits. Statit e-QC automatically recalculated
the upper and lower control limits as well as
the center line.
Example 2
Our report also allows the operator to note
where there may have been a change in the process;
we call this a "phase". In Example
3 below, by clicking on a data point, the user
can add a comment for the new phase. Statit
will automatically show a break in the line
for where the change occurred and again automatically
recalculate the control limits and center line.
Example 3
