    Thanks for your reply Paul, its one of the more valued ones I have received. I believe our thinking is in line with yours which is good to read. During this theoretical study phase we are intending to make use of a system diagnosis tool to underpin a system diagram which has already been compiled by our VP and reports. It’s basically the same template but uses better questions around SIPOC and should gets the user to start ‘systems thinking’, and searching for that ever elusive data to back up their claims. We’re also big on getting process mapping exercises done up front of any work, mapping out the real process as opposed to working with the perceived.
    Thanks again for your advise, I shall keep you all posted on progress and learning.

    Glen,
    I have to agree with Bobs last comment. Looking back over such a long time period isn’t going to tell you that much because you won’t be able to understand what was behind any special causes. Personally i’d take the last 20-30 data points to establish some limits and then continue to track the data from there on in, again though making sure that no special cause were within the learning phase (process running as normal). Afterall. the use of control charts are a way of predicting the future performance of the process as opposed to looking at it historically. Minitab would help you calculate the limits or you can do it by hand but i wouldn’t be that tempted to start spending money on software to carry on. Whats wrong with a pen and paper people? At least using this approach you can assign the reason behind any signals as well as document the action taken by writting on the chart. The chart will then effectively become a working diary of the process.
    Have fun!

    Hi JW,
    You need to identify the needs of the customer and ask them what they need with regard to the proceedures? How do they use them?, what might be improved? etc. I know that one of my training examples used the production of documentation to help us calculate process Sigma (defects per page, etc) so measures can be applied. Don’t think about what to measure though until you have good reason to pick measures which will be determined by talking to the customers – hope this helps
