Ok let’s move to our topic.

How to calculate manpower using takt time.

That’s very simple.

Just divide the total work content in man minutes by the takt time in minutes. You can refer formula in below picture,

Example calculation

Let’s take the same example we have used for doing manpower calculation in our previous article.

In that example,

Total work content in man minutes was = 5 + 8 + 6 = 19 man minutes

Takt time was equal to = (420 + 420) / 5000

= 0.168 minutes

Now we have everything for manpower calculation using takt time.

But, wait minute….

It’s always safe to consider some efficiency loss in calculating manpower.

Let’s consider 85% efficiency. That means 15% is lost.

Now, we need to adjust takt time to consider this efficiency loss.

Takt time correction = 0.168 x 85%

= 0.1428 minutes

(Note : For example suppose your process has 15% rejection. And your present demand per day is 100. Now you need to produce 115 products for giving 100 products to customers. So our actual demand is increased from 100 to 115. Hence the takt time decreases.)

Manpower required is equal to

=19/0.1428

=133.05

Rounding up it will be 134 manpower per day.

You can see that we have got same result in previous method.
