We often find truck or similar means circulating through space without a set route in the operation of several companies. These trucks only respond to requests and needs that arise from those who are in the operation. This traditional response model is called a taxi concept, in which this back and forth is a response to requests. It is a costly solution and it difficult to manage. This model undermines productivity - if the company has 10 trucks and they are occupied 90 percent of the time, the probability that when it is really necessary, all of the trucks are busy is incredibly high.
This option is therefore seen as a source of waste, variability, and difficulty in handling and delivery times. Alternatively, the use of "mizusumashi" is proposed. Mizusumashi is a Lean KAIZEN™ methodology tool that is synonymous with logistics operators and that translated literally means "one who moves easily." The purpose of mizusumashi is to ensure the supply of materials, components and information, guaranteeing that employees fully focus on tasks that add value. Using a logistic train, mizusumashi works as a subway, with set routes and times, reaching each station on time (the 20-minute cycle is the most common). Involving a bottom and easy handling cost, this solution promotes high productivity and allows the execution of a cyclical standard work.
Mizusumashi stands out because it cuts across various industries and services and changes the traditional process, eliminating waste and increasing productivity. Besides being economically advantageous, it allows to increase the quality and flexibility of operations. In short, mizusumashi increases the profitability of the organization and reduces the cost and Lead Time.
