Process consistency is measured by evaluating the variability of several items measured from the same process. For instance, the number of M&Ms in several bags should presumably be the same. If, however, they are not consistent, it does not necessarily mean there is a problem. However if there are outliers (some bags with very few M&Ms and others with a lot) then there is a problem in the packaging process. Some variability may be normal but excessive variability is not normal. This assignment is about the determination of variability in the outputs of a process and the determination if the process is in control or not.
This assignment requires you evaluate the data (on the next sheet) and determine if the process is in control or not. Please refer to the chapter on Statistical Process Controls for the procedures to do.
For all questions, clearly explain/show your answers. For the Analysis section, justify your answers with the appropriate graphs, statistics, equations, etc.
Analysis
a) For plant #1, please describe what parts of their processes have the greatest problems
b) For plant #2, please describe what parts of their processes have the greatest problems
c) For plant #3, please describe what parts of their processes have the greatest problems
Consulting (7 points each)
d) Given what you found in question a) what concrete recommendations would you make to M&Ms?
e) Given what you found in question b) what concrete recommendations would you make to M&Ms?
f) Given what you found in question c) what concrete recommendations would you make to M&Ms?
g) What other examples of data could be collected regarding M&Ms that could be analyzed with SPC?
General Understanding
h) If M&Ms wanted to conduct an SPC analysis of broken pieces, what data would you recommend they
collect?
i) … and how often should they collect it?
j) … and where would you recommend they acquire that data?
k) … and what would you do with the data?
l) … and what are the implications of that data?
m) If you ran M&Ms, what kind of SPCs analysis would give you the greatest competitive advantage?
