Jon has blogged about takt time many times before. Most recently he offered a free Excel based takt time calculator.
The tricky part about calculating takt time is normally associated with what to use for the daily demand number.
Do you look at the past 12 months? Do you average things out or look at the median? Should we plan for peak demand or use buffer and safety stock to protect us from these swings? What about including sales forecasts, which we know are always wrong?
So, you see, this takt time calculation is never quite as easy as the lean books make it out to be.
With this said, I’d like to challenge the fine readers of Gemba Panta Rei to a little takt time competition.

Let’s assume the following:
• Company makes one product
What’s the takt time?
[Note from Jon: From the list of people who give serious and thoughtful answers to this question we will draw two names at random to be the lucky winners of the upcoming book The Illustrated Toyota Production by Ritsushi Tsukuda, to be published by Gemba Press very shortly.]Comments are moderated to filter spam and inappropriate content.
