    Robert thanks very much for your advice. You are right that I am trying to predict lost passengers over a timeframe. My thoughts were that I would come up with a range of probable outcome values, however, I am not sure what the method is to do that. I do have access to Minitab, what function/method should I look to apply to the spread of data?

    Appreciate your further help.

    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.
