Continuous improvement of the speed and efficiency of processes

[hasinam2206]

The implementation of lean manufacturing tools directly affects the speed and efficiency of all processes. This is confirmed by Little's law, which establishes a connection between the order fulfillment time, the number of orders and the speed of their processing:


T is the average time spent on order fulfillment (how long it is in the system);
W — average number of orders in the system;
S is the system throughput (average order fulfillment speed).
According to this formula, the time it takes to bahamas mobile database complete a task depends on the number of tasks in the system and the speed of implementation. Lean manufacturing tools can influence the speed of task completion by investing in equipment, training, consulting, or hiring more workers.

The number of tasks in the system can be optimized without additional costs by limiting the input using the pull method.

Let's say a consulting firm creates custom business plans. The current team completes an average of 6 projects per month, and 12 plans are being developed at any one time. So, according to Little's Law, the average lead time is 12 / 6 = 2 months.

We are talking about flow production, so do not be surprised that six business plans are created per month, and the time to develop one ultimately takes two months. One of the 12 business plans enters the process and goes through its stages, completing them only after the same stages have been passed by the other 11 projects in the queue before it.
