Determine the average times for each step by carwash type.

Calculate the average cycle time.

Note the lead time for each system and why this is important.

Calculate the Takt time for each system.

Takt Time is the average time one unit is produced $($or washed in our scenario$)$

For example, at the Boeing Renton plant, it takes $9$ days to build a plan $($Cycle Time$),$ but they produce $42$ new $737$s each month or one every $8$ hours $($operating $16-$hour days five days a week$).$ A new plane comes out every $8$ hours, and this is their Takt time.
