|Using Measurements - | |Takt Time |
| | |TAKT TIME: Takt time is the pace at which the customer is demanding/buying a particular product or service. It is the rate (time) at which a | |person/item/document/ action, etc. needs to be served or completed at each step in a process in order to meet customer demand, in order for | |work not to pile up. It is the actual work “touch” time and is independent of the number of people doing the work. | | | | It is simply the number of work minutes in a day, a week, or other chosen time frame, divided by the number of units of work to do (demanded | |by the customer) in that same time period. Takt time is not how long it takes to perform a task. It is used in Lean as the rhythm or | |heartbeat of the process, i.e., if the customer wants a service every hour, the program/office should feel the heartbeat of producing a | |service every hour. Takt time cannot be reduced or increased except by changes in production demand or available time to work. | | | |“Takt” is a German word for ‘pace,’ 'beat,' or 'rhythm'. Takt time is one of the 3 Elements of Just in Time. |
Lean 101 Using Measurements: Takt Time
|Lean = Meeting customer demand in a timely way |
Takt Time is the pace or rhythm of work production needed to meet customer/client demand. It is the available work time in a specified time period/frame divided by the number of units of work needed/demanded in that same time frame. It takes into account any shifts worked and makes allowances for planned unavailable times (for team briefings, standup/standing meetings, breaks, planned maintenance, etc.).
Takt Time is a useful concept for balancing demand and supply/resources. It is simple to use where the demand rate is consistent and/or consistently known but can also be very useful where demand fluctuates and where the time resources are variable (staff come and go; there are interruptions, etc.).
