    To reinforce these points, check out these two sites

    Random correlations that make no sense: http://www.tylervigen.com/spurious-correlations

    Many ways to get the same correlation results with different data: https://www.autodeskresearch.com/publications/samestats

    First link reinforces correlation does not equal causation, and second link proves you need to look at the data graphically to understand why it is or is not correlated

    I also like using DMAIC when conducting a Lean project or series of events. Here are some tools or things to consider for each phase. I’m sure others have some ideas on what works for them.

    • Define would still require a project charter
    • Measure would include a VSM or process map, gemba observations, time studies, spaghetti diagrams and interviews with workers and staff. More advanced projects would include standardized work combination sheets, and takt time
    • Analyze would include identification of waste, root cause analysis for flow issues, data analysis on flow constraints or delivery issues or quality issues
    • Improve would be similar to Six Sigma, with a pilot study showing that the changes will work, or the list of kaizen events conducted. Tools would include a layout of the area, some 5S activity, kanban systems, poka yoke, andon systems, etc
    • Control would be a communication board, visual controls, 5S audit process, documentation changes, huddle board meetings, metrics to monitor each day, etc

    I also use an A3 for project status updates, project reviews, or displaying on a communication board

    Hope that helps

    @straydog Do you have any blog posts or articles about the ASQ nonprofit work that was done? Sounds like a great case study!

    Shouldn’t the project success be dependent on the impact to the company in dollars? If I get a 10% reduction in rework, which yields $150,000 per year, that may be a better project than one that gets an 80% improvement in cycle time, but may equate to only $25,000. It always comes back to money. Getting caught up in % improvement and forgetting about money will eventually cause your six sigma initiative to fail, despite the improvements made.

    Or you can take the initiative and either talk to your boss about it and ask to be on “the list”, or order a SSBB primer through ASQ, study the material, complete a project and take the exam. Either one will show that you are dedicated to getting your certification, and most companies will look more favorably on that, instead of waiting to be asked.
