From the Archives of a Common Sensei Volume 20: THE KANBAN CALCULATION


If your organization is beginning the “LEAN Journey” or if you are having difficulty executing your Kanban ordering, perhaps this blog volume 20 will help you. These formulas for “standard/ordering” and “inter-process” Kanban were derived from work we did at Toyota Industrial Equipment (TIEM) during the early days of the 1990’s, but may also be relevant in your organization. As you might suspect, the standard Kanban calculation formula is generally meant for external ordering, and the inter-process Kanban calculation is generally used only when material is transferred (moved) internally. When reviewing these formulas to be used as guides, I have presented the suggested formulas and considerations. These formulas have been used in a variety of JIT and Kanban driven environments since I left Toyota (TIEM) and have helped create enormous value in the form of: shorter order lead times, shorter processing time, less inventory expense, less handling, less space, better quality, lower engineering costs, less overall waste, lower financial costs, etc. for those who choose to take deployment seriously. The use of Kanban must be executed with high discipline! Anything less is likely to result in errors and shortages of supply. The implementation of Kanban alone in an organization is not likely to produce the intended benefits mentioned above! This is where the culture of many organizations MUST be tackled at the same time (as discussed in our previous blogs). Every associate must understand the seriousness of their actions and the consequences of not performing their role in the overall process.

True value creation requires that every associate understand their role in executing to plan AND perform that role as intended!

As has been stated in other articles/blogs, this example of methods used or previously used at a Toyota operation are only meant as examples for consideration in your organization.  Hopefully you will benefit from this and previous “ideas” we have included in our blog postings.
