    I’ve just been introduced to a Yamazumi Board and was wondering if anyone has had any experience with this tool? The process itself makes sense, but making the chart is cumbersome to say the least. Looks like a lot of useful information can be gained from this type of effort.

    Thanks for any input!

    My team used them (6 of them) throughout the plant. The critical step to making this board useful is making sure that ALL of the cycle times you assign to each process step is accurate. I cannot stress this enough. Also, put the time and effort in to training your team members and team leaders (if you have them) to use this tool without your help. The goal is to get your planned cycle time as close to your customers Takt time as possible, by balancing the process and removing waste. The steps should be written on magnets and the magnets cut to cycle time width. Good luck.

    I appreciate the feedback as it sounds like you have integrated this tool into your continuous improvement activities quite successfully. We’re just starting to use it and are developing our own program to teach others how to develop the chart. Right now we complete the process by hand and draw the diagram out. There are those who think we should use a spreadsheet as it would be easier. What method do you use, manually or a spreadsheet? I haven’t been able to find a template for the graph anywhere (Google, Yahoo, etc).
    Sounds l ike you use a magnetic board, which is interesting. We may try that one.

    Thank for yor reply!

    Hi all, how the yamazumi is different from VSM? It will be of great help if someone tell me the difference in terms of effectiveness and industry specifics?

    The way we have used the chart is to produce and validate the VSM first, identify those areas you want to improve (Kaizen Burst), and then develop the Yamazumi Board/Chart on the process you’ve chosen to improve.

    The VSM is at a “5000 foot” level, whereas the Yamazumi Board/Chart is at the “Street Level.”

    It works very well, and is easy to develop with a magnetic board or chart paper and different colored markers (green, yellow, red) to identify value and NVA steps in the process. Walking through the steps it will also help to balance the line at the same time. There are Excel templates that are available, but are expensive, and I was hoping someone had a template here.

    Good luck!

    Hi,
    I found an interesting article about Yamazumi here:

    http://adaptivebms.com/yamazumi-intro/

    There is also a link to a free Yamazumi template. Looks really good.

    A Yamazumi is essentially a stacked bar chart, used to visually represent how level workload is.

    I have used it to demonstrate a number of different features, examples:

    1) Cycle times of process steps/groups of process steps. This will show you if you need to re-allocate sub process steps to even out workload and remove a bottleneck, or if you need to allocate heads in accordance with the cycle time ratios, again to remove any bottlenecks.

    2) Demostrate work across a period of time, say across a working month or a sales period. This will show if your work is unevenly distributed across a period of time, and let you see where you need to level the work out, to remove peaks and troughs, etc.

    3) To compare cycle times by different employees across the same steps. This helps to identify best practice in terms of the fastest cycle time (though you need to ensure the best practice method you choose also still ensures quality).

    4) To compare workloads between team members. If for example, accounts are split between different people, this may be assumed to be an even split, but some accounts are more complex than others, therefore an uneven workload.

    As mentioned, they are essentially stacked bar charts, so if you wish to create on an excel spreadsheet, you can do and this takes little time.

    Michael.
