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
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...
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.
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.

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.
What a great video! Taking a course in Global Supply Chain Management and your explanation has helped a lot! Love the example and drawings; very clear :)
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!
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...
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.
[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.
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
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
You reached one of the most important goals in this video: KEEP IT SIMPLE!

Hi Rafael Wollmann
Good explanation

I couldn't have gone without saying thanks for the great explanation.
Thank you for the excellent video! Please make more! They are very useful
I was able to comprehend this with no confusion-thank you and great video!
Great way of explaning such a complicated topic..
AMAZING VIDEO! So clear and well explained. Thank you!
This is an excellent video. Simple, to the point with clear visuals supporting it.
Clear and easy to understood. Great job!
Excelente video, Thank you for teaching.
Easy for newbie to understand. thanks for such good and simple explanation.
Thank you for this video. Easy to understand. !!
Great explanation! The best I´ve found. Thanks
Great Video! I hope you don't mind but would like to add on Down time. Downtime is when production is interrupted.
I love teaching inspiring IE's.
Amazing!! simple and to the point, Thanks..
Excellent explanation, excellent examples, very good video.
I like your teaching style as well as the imperial example you provided. It is really helpful...
Thank you

hello, thanks, great job! if you add 1morr worker in step two, you reduce cycle time, but the first unit will be late by 1.5 secs. Agree?
wonderfully explained...great job...thanks
Now I understand! Thank you
Well done! Nice change from the powerpoint presentations I normally see for this!
Amazing Explanation... good video .. Thanks
Excellent teaching 👌👌👌

How do I buy one of these circles adhered to paper?
the 2nd green circle have to wait for the other 2 colors to be completed prior processing green again.
Therefore total leadtime is 63 secs.
the colors do not carry any significance. you just want to put out circles.
good stuff.
thank you
Excellent
