A reader pointed out that the takt time for posting the 101 kaizen template has exceeded. It is true that we have not been hitting a consistent 1 template per 3.5 days. To meet our goal for 101 of these by the end of 2008 we will need to recalculate our takt time. Conveniently, we have a takt time calculator as a template for this.
There are two sections to this kaizen template in order to make it easy to show two possible takt time scenarios. There may be an average takt time and a takt time during peak volumes. This information is useful in designing production lines or equipment so that the maximum capacity as well as the daily average can be taken into consideration.
The two sheets in the graphic above are used to illustrate that there are two different shift structures with different numbers of working hours and thus different takt times on these days. For example if there was an “A” shift working four 10-hour days and a “B” shift working three 12-hour days for a 7-day operation the takt could be matched by adjusting average demand.
This takt time calculator will calculate takt time for you under a variety of conditions such as break times, number of working shifts, shift structures and working hours per shift. Fill in the white cells. The blue cells will calculate automatically. The sheet is protected so that you don’t accidentally delete the formulas. It is not password protected so feel free to select Tool / Protection / Unprotect Sheet if you would like to modify this template.
Back to the issue of non-performance to takt time on this blog. What is the kaizen action to be taken? Of course root cause analysis and corrective action must follow, but an immediate recovery plan is necessary in the mean time. For illustrative purposes the takt time calculator was modified to show the original plan of one kaizen template every 3.5 days, not adjusted to one every 2.1 days based on the remaining number of kaizen templates (95) the remaining number of blogging months (11) in 2008 and a more realistic number of “available days” per month for blogging (20).
A kaizen template every two blogging days may get to be boring, but a promise is a promise so the challenge will be to meet this goal while keeping it fresh and interesting.
