Explain statistical process control(SPC) and how it
relates to continuous process improvement. Relate Demmings 14
Quality Points and explain how statistical data can assist with
quality improvements efforts.
In quality control, statistical process control (SPC ) is often
employed to analyze the process capability in manufacturing or
service operations. Explain the following with an example each
:
What is a p chart ?
What is a c chart ?
There are 3 machines in your factory which can produce a ruler.
The rulers as produced has a spread in length between 12.5 thru
12.4 inch.
The standard deviation of the 3 machines are
* 0.15
* 0.09
* 0.13...

Given the standard deviation of the 3 machines are as follows,
calculate the process...
Consider a process under statistical quality control. The upper
specification limit of the statistic of interest is 101, while the
lower specification is 42. The sample plan is for 7 samples per
period. The average range of the process is 13. What is the
capability of the process assuming it is centered exactly between
the specification limits and the statistic of interest has a normal
distribution?
Applications of Statistical Process Control and Quality
Improvement Tools in Transactional and
Service Business.
The tools are:
1. Cause and Effect Analysis.
2. Check sheets/ tally sheets.
3. Graphs.
4. Histograms.
5. Pareto analysis.
6. Scatter analysis.
7. Control charts.
. For discussion, I want you to discuss how these tools are
being used in your realm of work? If they are not
being used, then how do you see them being used? Identify at
least one tool being used...
