Total lead time = 16+12+208 =236 minutes

Value-Added Lead Time = Time Taken for Cutting and Assembly + Time Taken for Decoration

=(6 + 10)=16      

Non-Value-Added Lead Time                    

Move Time        =12        

Within Batch Wait Time (16*(14-1))        =208     

Total Lead Time =16+12+208     236minutes     

Step-by-step explanation

The value added Leadtime = 16 minutes (cutting and assembly + decorating process time)

Non-value added lead time :

Move time = 12 minutes

within batch wait time = ( total time to perform operations) X ( batch size - 1)

within batch wait time = ( 6 + 10) * ( 14-1)

within batch wait time = 208 minutes

Total lead time = 16+12+208  =236 minutes

The Value added ratio = Value added lead time / Total lead time

Value added ratio = 16 / 236

Value added ratio = 6.78%
