Great way of explaining how takt/cycle/lead time works. As a special bonus how QUALITY is forgotten so production metrics are met (Did you see all the scrap that was generated?). I think it is always good to add some extra time to ensure quality. This way PRODUCTION is not pressured to meet takt/cycle/lead metrics and forget about QUALITY. I am a software engineer, and I think this is an excellent video don't get me wrong. But Quality should also not be forgotten, please add some extra time to meet customer demands and quality.

The difference between Cycle Time (CT) and Lead Time (LT) is academic, but valuable enough for practitioners, in order to avoid employee's misunderstanding. Here we go: 1. CT is a RANDOM VARIABLE and is associated to the process. CT is subject to variations, because every productive system has variability, some more intense and some other ones less. That's why it is considered random, you have the Average CT and the variance (or standard deviation) of that. The variance (or std dev) can be increased based on downtimes for example. 2. LT is a DECISION VARIABLE and is associated to the decision maker and customer (client). The decision maker needs to know which is the CT and its variance to estimate the LT. With LT on hand and known due date, the decision maker can run the planning process in order to meet demand on due date. In summary, CT needs to be less than or equal LT to meet demand. Analyzing it quickly: If CT is greater than LT, your process is not capable to meet demand in due dates. If CT is equal to LT, your process must have zero variability, otherwise your process will not be capable to meet demand. If your CT is much lower than LT you will have inventory. So, you need to keep control of your process in order to keep low variability under control, to have a consistent CT to estimate LT and run your process at your Takt Time.
I'm glad that my prof shared this video to further clarify the difference between these times 😊 Thank you, for your clear and easy to understand explaination
My note for my future dumb-dumb self when I get amnesia Takt time = time you need to complete customer demand Takt time = [Working hour - non working hour] : Customer demand Cycle time = time you need to produce 1 product Cycle time = {[value added activity (VA) + non value added activity (NVA) + necessary non value added activity (NNVA)] - downtime } : production capacity Lead time = order completed - order received or process ended - process started Lead time = value added activity (VA) + non value added activity (NVA) + necessary non value added activity (NNVA) In real life you need to consider allowance for the worker, and it's called standard time. Takt time is the maximum limit for cycle time When cycle time > takt time, then it's too slow (bottleneck) and need some manipulation/fixing in the production line. 😢 👎 When cycle time = takt time, then it's a meh. 😕 Be careful when workers slack it will pass the time limit. 😢 When cycle time < takt time, then the process is done too fast. 😊 👍
Hi Chris, I would consider waiting for a part the lead time for that part. You are the customer of that company, and they then have to calculate their own takt time to satisfy your demands. Now if the part is coming from your own company, and you are waiting on another department, then it is built into your overall lead time (raw materials into your plant, finished product out). If your company is very large, you may end up calculating lead time for individual parts and running a pull system, letting each department ensure their lead time and cycle time stays in sync with your finished product assembly pace- which should be pacing to meet your customer's demand.
How to calculate DISTANCE travelled by component when "takt time" of component and conveyor speed is given.? Speed of conveyor = 8 meter/min (Stop and Go type Conveyor) Takt Time of component = 50 seconds Distance travelled by component in Takt Time or Pitch of component = 2438.4 meter How much distance would be travelled by component in 10 minutes.. Please explain your answer also, so that i can learn the formula for similar problems
Thanks for an illustrative video. VSM you showed was showing 1 hour of inventory time between stations, which was a bit confusing to me. Can you please explain!
Hi. In the balance of a production line, the workstations are changed (in the video is an example between times 8:05 to 8:20). I did not find any research article to bring this balance. You have some article engineering support to put it in my thesis. If possible, I will be very grateful.
I still have a doubt about tack time is a measure of excellence in any company. But it doesn’t mean that it is happening. It is a measure of comparison to what is really going on in lead time meaning if the process is achieving the goal of meeting the customer demands. And then the cycle time is what is really going on the process. After that you use the measure of comparison or tack time to get the results of each process in the company and the result is how to map slower process and improve them. Is that? Sorry for my English, I’ve been speaking german often here in the company and besides that I live in Brazil and I’m Italian so unfortunately the most important business language is as it was one year ago. Thank you for the video and it helps a lot. But still I really need to know if I understand correctly.
To improve profitability, that is to increase production with same or less cost, simply have the circle marker employee draw one circle, pass it on to the cutter employee, who then stack 2 sheets of paper (even more, depending on the quality of the scissor), then cuts these 2 pieces of paper at a time, therefore producing 2 circles at a time. You figure out the rest...
Why didn`t you add in the video about defects?? waste!!!!! the operators not being consistant with there process??? especially when sticking the circle to a piece of paper!!!!! here, there, everywhere!!!!!! : ( under pressure to meet demand?? quality suffers!!! in the TIMWOOD meaning, D for defects!!! customer returns.......................................... a bit of extra time should be added for the process!! after all, we are not robots : )
Absolutely waste plays a big part in setting your planned cycle time. For the purposes of understanding the theoretical takt, cycle, and lead times, waste makes it a little more murky. Waste is what gets in your way of achieving your desired states. Thus, understanding your theoretical demand verses your actual helps you see what you need to work on to achieve your goals.
Can you tell me if I might be able to edit/use this video? No offense, but I would like to cut it down and fast forward through some parts - it is very useful but for my purpose/intention I would like a short version (I don't plan on monetizing, and I would provide you with the result if you would like to do so). Please let me know if this would be possible. Thanks
I searched quite long to find a video which explains this topic easy and understandable, here we are and i thank you for making it! Go on and use this talent to make more...
Norman Winston cycle time is not defined by the sum of times of all operations. You have to count the rate at which a produced is finished. The first product is the only one which takes 25 seconds to get finished. The second one will take less because the first station started working on a second product while the second was finishing the first and so on... and you take time to a very high number you will realize that the slowest work stations determines the rate of finished products
If it is really custom, it can be tremendously difficult to get a good sense of pace. Ideally, over time, you can identify trends and work to set known high points, low points, but some things are really unique. Instead of trying to get a pace for a month, you might be able to look at 'worst case scenarios' on how many would be needed and try to get a sense from that. Sorry, no great answers from me, at least...
[Hope to get reply] Great video! Why when calculate the takt time use 7.5hours and not putting 3 operativers into account? For a bigger assembly company shall we calculate available time by considering of head count or not?
Great question. Takt time is calculated as the demand from your company for your customer. So, how often does the company need to produce one item for the customer. You may be looking for the planned cycle time. If you have 3 assembly stations producing for the customer, you may want to calculate the planned cycle time for each to meet your customer's demand (takt). So, in that case, you might calculate takt x 3 to understand the demand on each assembly station. Further, you might want to build in a safety margin for change overs, or things of that nature, so you run a little faster than the demand. That would end up being your planned cycle time at the assembly station level.
The difference between cycle time and lead time seems academic to me. Cycle time is frequency of a completed unit, whereas lead time is the measurement of time for a unit to travel through the entire process. I dont see any value in the difference
colin roach The value in knowing cycle time is to be able to measure how your process is producing- is it running normally or not. This highlights abnormalities and helps to locate what problems are getting in your way of running normally. The value in knowing lead time helps highlight how you are serving your customer (if it is a made to order process) or how much inventory there might be in your process. Typically longer lead times indicate larger inventory levels.
+colin roach Lead time clock starts when the request is made and ends at delivery. Cycle time clock starts when work begins on the request and ends when the item is ready for delivery. Cycle time is a more mechanical measure of process capability. Lead time is what the customer sees.

My note for my future dumb-dumb self when I get amnesia
Takt time = time you need to complete customer demand
Takt time = [Working hour - non working hour] : Customer demand
Cycle time = time you need to produce 1 product
Cycle time = {[value added activity (VA) + non value added activity (NVA) + necessary non value added activity (NNVA)] - downtime } : production capacity
Lead time = order completed - order received or process ended - process started
Lead time = value added activity (VA) + non value added activity (NVA) + necessary non value added activity (NNVA)
In real life you need to consider allowance for the worker, and it's called standard time.
Takt time is the maximum limit for cycle time
When cycle time > takt time, then it's too slow (bottleneck) and need some manipulation/fixing in the production line. 😢 👎
When cycle time = takt time, then it's a meh. 😕
Be careful when workers slack it will pass the time limit. 😢
When cycle time < takt time, then the process is done too fast. 😊 👍
