What is an operator balance chart?
A graphic tool that assists the creation of continuous flow in a multistep, multioperator process by distributing operator work elements in relation to takt time. (Also called an operator loading diagram or a yamazumi board.)
How do you do a Yamazumi chart in Excel?
Click on the QI Macros menu then Lean Tools, then Yamazumi Chart. You have a choice between templates with 10 and 15 operators. Input step names, cycle times, and color codes for each step to create the Yamazumi chart. Click on the apply colors button to update colors in the chart.
How do you do line balancing?
How can you achieve line balancing?
- Calculate takt time. Since the goal of line balancing is to match the production rate to takt time, being aware of your takt time is essential.
- Perform time studies.
- Identify bottlenecks and excess capacity.
- Reallocate resources.
- Make other improvements.
What does Yokoten meaning?
Yokoten is a Japanese term that can be roughly translated as “across everywhere.” In the Japanese lean system, it is used to mean “best practice sharing.” In short, Yokoten is used to talk about the transfer of lean manufacturing knowledge and practices from one operation to another.

What is a kaizen blitz?
Kaizen events, also known as Kaizen blitzes, are short-duration events, usually in the form of a week-long workshop, in which a facilitator guides a team in improving an area with a specific goal in mind.
Which method is used for line balancing?
For solving line balancing problems a number of methods are available, for example Heuristic, linear programming model, dynamic programming and comsoal (a computer method for sequencing operations for assembly lines). For intermittent flow system normally heuristic methods are preferred.
What is line balancing formula?
Line Balancing in Manufacturing Defined Line balancing is a production strategy that involves balancing operator and machine time to match the production rate to the takt time. Takt time is the rate at which parts or products must be produced in order to meet customer demand.
What is the formula of line balancing?
According to the Formula (1), (2) and (3), line balance efficiency is calculated as follows. η=[the total process time/CT*operation number]*100% =[50.4+63+63+61.95+57.75+36.75+42/(63*7)]*100%=85% Balance delay rate is calculated as follows.
How should a yamazumi board be constructed?
Hi Jesse, the yamazumi board should be constructed by the people doing the work with their own timings therefore should reflect the reality of what is actually done; not done by an engineer in a back room based on timings that are estimated or recorded for “costing purposes.”
What is a yamazumi chart?
Achieve optimal levels of productivity by using a Yamazumi Chart to help you identify and eliminate wasteful occurences in your processes.
What is yamazumi chart in Lean Six Sigma?
Discover more about Lean Six Sigma. Simply put, the Yamazumi chart is a diagram that allows you to immediately know when supply and demand are unbalanced. This way, organizations or companies have the ability to immediately rebalance the project to ensure that efficiency is always kept.
Is your yamazumi tool not functional?
A quick search of the Internet will surface several eye-catching tools that are simply not functional. If a Yamazumi tool does not allow team members to easily rearrange tasks, then it is not functionally fit to perform the intended purposes:
