TAKT time is the maximum acceptable time to meet the demands of the customer. In other words, TAKT Time is the speed with which the product needs to be created to satisfy the needs of the customer. The TAKT Time Formula = (Net Time Available for Production)/(Customer’s Daily Demand).
What are lean tools?
What Are Lean Tools? The Japanese word for waste is muda, which is defined as “uselessness.” Lean tools are designed to reduce Muda in organizations and improve quality control. In other words, Lean tools seek to eliminate processes that aren’t valuable.
What is net available time per day?
Net available time is the amount of time available for work to be done. This excludes break times and any expected stoppage time (for example scheduled maintenance, team briefings, etc.). Example: Customer demand can still be met by adjusting daily working time, reducing down times on machines, and so on.
What is operator balance chart?
Synonym(s): OBC. 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.)
What is line balancing in industrial engineering?
Line balancing is a production strategy that involves balancing operator and machine time to match the production rate to the takt time. In other words, the quantities of workers and machines assigned to each task in the line should be rebalanced to meet the optimal production rate.
What is called takt time?
The term takt time derives from the German word Taktzeit and translates to either “measure”, “cycle” or “pulse” time – depending on which source you read. Put simply, takt time refers to the amount of time a manufacturer has per unit to produce enough goods to fulfil customer demand.
What is takt time example?
The available production time divided by customer demand. For example, if a widget factory operates 480 minutes per day and customers demand 240 widgets per day, takt time is two minutes. Similarly, if customers want two new products per month, takt time is two weeks.
What is 5S checklist?

Which is the best description of a yamazumi chart?
Yamazumi is a Japanese word translated as huge mound, heap, or pile. A Yamazumi chart is simply a stacked bar graph. But by plotting process cycle time by process steps and listing the tasks within a process step as Value Add or Non-value Add, it becomes a powerful tool to not only aid in balancing workload but in highlighting waste.
What do you mean by yamazumi in lean?
Use a Yamazumi Chart to highlight the three broad types of process deficiencies to improve in Lean: Muda (Waste), Mura (Unevenness), and Muri (Overburden). Yamazumi is a Japanese word translated as huge mound, heap, or pile.
What is the purpose of the yamazumi board?
Yamazumi charts are used by Lean improvement teams throughout many process driven organizations. The Yamazumi board provides a mechanism to quickly rebalance a process when takt changes, and allows a visual indication of which operations are overloaded (beyond takt), and which are underutilized.
