The Trouble with Calculating Takt Time and Kanbans

At first glance, the formulas seem so easy.

Takt Time =
Work Time Available / Customer Demand

# Kanbans =
Reorder Point rounded to container size

So why are they so often calculated wrong?

Try this experiment...

Ask 5 of your people
to calculate takt time for the same process.

In most organizations,
you will get at least 3 different answers.

Why?

Units of Measure

Does that formula use daily demand? weekly? monthly?

Work Time Available

Takt Time Calculator

Jack deducted time for set-ups and change-overs. Jill deducted time for the daily Stand Up Meeting. Jim didn't realize that this team has a different break schedule than most other teams. The new-hire, John, didn't even deduct lunch.

Demand

Jack just blindly plugged in the number he got from his supervisor. Jim got the math wrong when converting monthly demand, trying to factor in the consideration that this team will be working every other Saturday next month. Jack was the only one who remembered to include multiple sources of demand (like spare parts, service parts, prototypes...)

And also try
the Kanban Calculator

If you ask 5 of your people to calculate kanbans for the same process...

you will probably get at least 4 different answers.

Kanban Calculator

Why?

Because calculating kanbans involves even more factors than Takt Time.

  1. Did you consider all elements of Lead Time? (e.g. requisition cycle, order cycle, fulfillment cycle...)
  2. How and why did you choose that factor for Buffer Stock? (to protect against Demand Variation)
  3. How and why did you choose that factor for Safety Stock? (to protect against Process Variation)
  4. Did you correctly use Average or Median? (based whether your source data fits a Normal curve)
  5. Did you consider whether the kanban is released when the container starts to be used vs. when the container is empty?
