    Given a set of data, how do you conduct a baseline performance analysis? Is this the same as a capability analysis?

    And, when looking at a set of data, how can you tell where the process changed?

    My assignment asks me to complete a baseline performance analysis and “if the process changed, you must select where it changed and compute your answers.” It later says “Divide up the data as separated in the last question.” What does this mean?

    @ssoe2020 What do you think? Why or why not? The iSixSigma audience is incredibly helpful, but they are not here to do your homework for you. They will, however, often help someone who shows they are putting forth a good-faith effort to understand the information on their own first.

    @ssoe2020 Katie is correct. Most of the regular posters on here will not do your homework for you. If you want to take a shot at it and come back for feedback or help you can get some very talented people that can help you i.e. @rbutler, @cseider, @Straydog, @Darth etc. @Darth actually loves to help people do their homework.

    The other issue with your question is the reference to “baseline performance analysis.” That is not, that I am aware of, a standard type of analysis. It might be a capability study but normally if some one wants me to do a capability study the say something like “do a capability study.”

    The entire point of the Measure phase is to baseline the current process. If someone were to tell me to baseline something then you would get Measurement Phase type information.

    As far as the part about “If your process changed……” You need more than a baseline to tell of the process changed. As we used to say “that is like owning one walkie talkie.” It takes two to make it work.

    Let’s see if we can’t get you off of dead center.

    You said the following:

    Given a set of data, how do you conduct a baseline performance analysis? Is this the same as a capability analysis?

    And, when looking at a set of data, how can you tell where the process changed?

    My assignment asks me to complete a baseline performance analysis and “if the process changed, you must select where it changed and compute your answers.” It later says “Divide up the data as separated in the last question.” What does this mean?

    1. Have you been given a data set to work with?

    2. Is what you posted all that you have been given in the way of a question or is your post a paraphrase of the actual problem?

    3. What is your understanding of the definition of the phrase “baseline performance” as it applies to a data set which (presumably) is supposed to represent process data acquired over some period of time?

    a. Given what you have posted, does the phrase “baseline performance” relate to the process mean, variance, median, IQR, or some other aspect or some combination of the properties listed?

    b. What kind of methods have you been taught to address questions concerning any of the items listed in a)?

    c. What kind of methods have you been taught to address changes in any of the items listed in a)?

    4. What is your understanding of what constitutes a capability analysis?

    5. What is your understanding of what a capability analysis evaluates?

    a. In any of your reading about capability analysis did any author conflate the phrases “capability analysis” and “baseline analysis?”

    b. Have you taken the time to check these two phrases using a Google search?

    1. If so, what did you find?

    If you can provide the answers to these questions you should have a partial answer to your original question and if you post your answers here perhaps I or some other poster may be able to offer additional assistance.

    I’m suspecting they were asking you to do SPC on your X’s or Y’s and see if you can find special cause indications which could be “a change in the process”.

    However, capability analysis and histograms and run charts can tell you lots of hints of where to maybe look.

    Best of luck
