What’s the difference between Lead time & Turn Aroun Time1September 27, 2012 at 10:19 pm #194103

Please find the definition for both terms,
Lead time: The amount of time, defined by the supplier/service provider, that is required to meet a customer request or demand. Lead-time is generally considered as the time between the Customer’s request initiation to Customer’s request fulfillment.
Turn around time: This time is in order to get a job done and deliver the output , once the job is submitted for processing center according to the customer request.
In nutshell, TAT generally takes about the time requirement to meet a customer demand internal to the processing center and Lead time considering both internal and as well as external to the processing center.

Thanks for your Input0October 10, 2012 at 3:02 pm #194197Lead Time=NVA=Non-Value Added Time
Cycle-Time=Touch Time or VA time
In any process LT is usually where you might want to concentrate your “leaning” efforts since it is usually much higher than “touch time”.0October 11, 2012 at 1:39 am #194198
Hari VSParticipant@harivs80Include @harivs80 in your post and this person will
be notified via email.As per my undestanding, Lead time starts when the request for the work is received and ends once the entire work is completed. But the Cycle time starts only when work starts and ends when it is completed.
“Lead Time=Total time from start to finish”. This may also include waiting time between the sub processes, if there is any.1September 15, 2013 at 7:17 am #195924lead time means the time start of process request ,to end of transit time.closure of availblity.
TAT mens turn around time of job request start to closure.

0July 21, 2016 at 11:34 pm #199920Hi,
I want to discuss about this situation in manufacturing company.
We received an order from a companny for a reparation.
In this case :
TAT for an operation= difference between the time when start the opertation(when operator take the part )and the time when the operator finish operation.
Lead time=the time when received the part in our company and the time when finish activity (the part is ready for delivery)0July 22, 2016 at 8:36 am #199922

0July 22, 2016 at 9:39 am #199923These are two different things. In simple words, time taken to meet demand of customer for any material or services is termed as Lead time. While, time taken to complete the project from initiation to finish is termed as turn around time.
Any company, would like to minimize both, so as to improve on productivity.
There are ways of doing it and that depend on type of projects.0November 23, 2016 at 4:12 pm #200247
randy sanchezParticipant@MARINESInclude @MARINES in your post and this person will

TAT-just like this situation (ex.)this would apply in maintenance department, the time start upon pick up the item just(for repair until the delivery of item or done repair).0November 28, 2016 at 2:08 pm #200262

I have always used Little’s Law for lead time (LT=WOH or WIP/average TP). This is a good representation of process performance and closer to what the customer can expect to feel. In my experience, turnaround time is typically measured from the start of work until delivery in cumulative units of time. Sometimes the start point will be receipt of order, but it has always included all the waiting time. Cycle time is the actually working time to get the task done (which also includes some non-value-add time). TAT and CT can be influenced by a variety of factors including the nature of the work or the order. That’s why I like Little’s Law as a measure of lead time and a better process indicator. It is more likely to be normally distributed and in control if the process handles a variety of items.
Best,
