Introduction
Value Stream Management (VSM) is an effective tool for collecting, evaluating and continuously improving product and information flows within an organization.
The method includes value stream analysis, design and planning. The ideal state of value stream management is to map the current state of the value stream based on the collected data.
The current state is analyzed to design a future state with less waste and shorter lead time.
It was developed in the.1990s under the framework of lean production. Due to the differences between value stream management methods, value stream management
There are communication and collaboration issues in practical applications, especially when different visualization processes and related computational processes are involved. These issues are common in departments,
The application of value stream management methods needs to follow relevant regulations.
The company develops principles and guidelines to ensure a common, standard approach to capturing, evaluating and continually improving value streams across the enterprise value network.
Figure 1 Communication issues at the supply chain level
This universal, goal-oriented value stream management application can reduce or eliminate much of the waste or eliminate the need for a single contact or audit.
Accountants perform multiple and redundant value stream data preparation.
The process of developing a unified value stream management analysis method brings comprehensive value stream analysis for different departments and different process types.
At the same time, based on the unified value stream management method, product flow and information flow are formulated to coordinate process planning (see Figure 2).
Figure 2 Integrated supply chain
A common understanding of value streams enables organizations to align their internal and external processes. A standardized approach to value stream management ensures
It realizes unified collection, visualization and calculation of value streams within organizations (including companies, institutions, suppliers, etc.) and along the supply chain.
All information or requirements in this document are transferable to any process type. Figure 3 shows the different process types to which this rule applies.
The product flow in Figure 2 consists of the material/energy and data related processes shown in Figure 3.The material/energy related processes can be further
The steps are decomposed into manual or automatic processes. For manufacturing, each process involves single-piece, batch or mass production.
Processes include services, trade or management processes.
