In 4, years, China has been a nation of farmers. By the time the People's Republic of China was established in , virtually all arable land was under cultivation ; irrigation and drainage systems constructed centuries earlier and intensive farming practices already produced relatively high yields. But little prime virgin land was available to support population growth and economic development. However, after a decline in production as a result of the Great Leap Forward —60 , agricultural reforms implemented in the s increased yields and promised even greater future production from existing cultivated land. Since China's political leaders have tried a variety of large-scale social experiments to boost agricultural production. First, a massive land reform program eliminated landlords and gave land to those who farmed it.

Creating A Value Stream MapVIDEO ON THE TOPIC: PlantFactory Kickstart Tutorial by Aya
Value stream mapping can be incredibly useful in various industries. Want to make a value stream map of your own? Try Lucidchart. It's quick, easy, and completely free. Value stream mapping is a flowchart method to illustrate, analyze and improve the steps required to deliver a product or service.
A key part of lean methodology, VSM reviews the flow of process steps and information from origin to delivery to the customer. As with other types of flowcharts, it uses a system of symbols to depict various work activities and information flows. VSM is especially useful to find and eliminate waste. Value stream mapping maintains that focus. You can start off sketching by hand and then move to VSM software for better communication, analysis and collaboration.
This type of mapping may be older than many people think. Examples of diagrams showing the flow of materials and information are contained in a book called Installing Efficiency Methods , by Charles E. Later, this type of diagramming became associated with the vaunted Toyota Production System and the whole lean manufacturing movement, although it was typically called material and information flow mapping, process mapping or other names, not value stream mapping.
The people most often credited with creating the Toyota Production System, starting in earnest in the s, include: Shigeo Shingo , a Japanese industrial engineer, Toyota consultant and namesake of the Shingo Prize for lean excellence; and Toyota executives Taiichi Ohno ; Kiichiro Toyoda and Eiji Toyoda Value stream mapping also came to be used in Six Sigma methodologies.
Lean and Six Sigma both have the same goal: to eliminate waste and create the most efficient system possible. But they identify waste differently. While lean practitioners focus on non-valued-added activities, Six Sigma followers focus more on process variations resulting in waste. Each has been successful in different situations, leading to the formation of Lean Six Sigma, a combined approach.
Jones, founder of the Lean Enterprise Academy in the U. Value stream mapping is a powerful method to ferret out waste in any process, not just manufacturing. That focus on value keeps the analysis targeted to what really matters, allowing the company to compete most effectively in the market.
Foreseeing or facing any competitive threat, lean practitioners can make good use of VSM to produce the most value for the customer in the most efficient way possible. It can and should be used on an ongoing basis for continuous improvement, bringing better and better process steps on line. VSM allows you to see not only the waste, but the source or cause of the waste. Value stream mapping, as with other good visualizations, serves as an effective tool for communication, collaboration and even culture change.
Decision makers can clearly visualize the current state of the process and where waste is occurring. They can see problems like process delays, excessive downtime, constraints and inventory issues. Although its typical purpose is eliminating waste, VSM can also be seen from the perspective of adding value. Value is something a customer is willing to pay for. Muda is lean terminology for waste. While Value Stream Mapping is core to lean methods, it often requires a substantial investment of people and time to do it, and if not applied wisely, it can be wasteful in itself.
You of course want profitable applications of value stream mapping. It requires team members skilled in carrying out advanced VSM, and it may take days, weeks or even months to carry out some involved mapping projects. Think of it as a powerful tool central to lean methods, but not every circumstance lends itself to value stream mapping.
You need to balance potential value with the work necessary to conduct the VSM. You might choose to start small, with a limited focus and a limited budget, get the win and then move on to something more complex and potentially rewarding. Oftentimes, senior leaders may try to bite off something too large initially, and the effort may struggle due to its complexity and possible inexperience of the team.
Often, a fuller look will be required. However, keeping those caveats in mind, an individual could try VSM on a budget for a simple review that might produce results or at least help you to better understand VSM. Just keep in mind that this would be a tiny taste of what expert value stream mapping can accomplish. In manufacturing : To find waste in the production process by analyzing each step of material handling and information flow.
This is where lean methodology got its start in the s at Toyota, and lean methods and value stream mapping remain key to manufacturing throughout the world. Of course, they have since spread to other fields and have become intertwined with Six Sigma methods and Lean Six Sigma.
Supply chain and logistics : To root out waste and costly delays at the various points on the supply chain leading to finished product. Service industries : To improve the value and find waste in the activities required to carry out any service for external customers.
Healthcare : To improve the steps required to treat patients in the most effective, timely, cost-efficient, high-quality way possible. Office and administrative : To find wasteful steps and improve the service provided within a business to internal customers. In value stream mapping, the process items that flow through the value stream are determined by the field.
For example:. Diagramming is quick and easy with Lucidchart. Start a free trial today to start creating and collaborating. VSM symbols vary in different places, but they fall into these four categories: process, material, information and general. The symbols can be complicated, although some simply imply their meaning in a layman's sense, such as a truck icon for external shipments and eyeglasses for something to go see. Here are some widely used symbols.
Need more detail? See this in-depth article on VSM symbols and how to use them. Each action contributes value to the finished product, ideally working together efficiently to create a continuously flowing stream of value.
The first step toward creating a lean environment — increasing value and removing waste — is analyzing the value stream. This provides the foundation for creating an improvement plan. By examining the current state of a system, actions that add to value creation can be clearly separated from those that create waste, making it easier to locate opportunities for improvement. Value stream mapping supports stream analysis by simplifying a complex system into a map.
The map illustrates the outcomes of the value stream analysis, providing a visual tool to facilitate understanding and communication.
The next section outlines the steps for completing a value stream analysis, creating a current state map, developing future and ideal state maps, and ultimately carrying out a lean plan. These steps are best practices for VSM and provide organization to value stream analysis, hopefully leading to the best possible outcome: an efficient and integrated material and information flow system.

Contents What is value stream mapping? Make a value stream map. What is value stream mapping? History of value stream mapping This type of mapping may be older than many people think. VSM purpose and benefits Value stream mapping is a powerful method to ferret out waste in any process, not just manufacturing.
VSM caveats While Value Stream Mapping is core to lean methods, it often requires a substantial investment of people and time to do it, and if not applied wisely, it can be wasteful in itself.
Potential uses of more extensive VSM include: Cases involving multiple functional areas or departments. To make the case for a large investment that will result in much larger savings. How VSM is used in different fields In manufacturing : To find waste in the production process by analyzing each step of material handling and information flow. For example: In manufacturing industry, materials are your items. In the design and development field, designs are your items.
In service field, external customer needs are your items. In the administration field, internal customer needs are your items. What symbols are used VSM symbols vary in different places, but they fall into these four categories: process, material, information and general. Identify the product or product family to be studied and improved. You typically put together a team to do the mapping and analysis, depending on the size of the initiative. If inexperienced, the team will need training in VSM.
Some larger companies may have a value stream manager. You could use A3 analysis of root causes to do this. Bound the process , which means determining the limits or scope of your map. Or are you starting with one problematic part of the value stream? Now, do the VSM walk, as outlined in upcoming steps Walk or directly experience the process steps and information flow required to put out the product or service. Some veteran practitioners do the walk in reverse, starting with the customer.
You might do the walk multiple times to gather more information, filling in any gaps. In lean manufacturing, all of the steps might take place in a single location that inventory enters and then leaves. Collect process data on your walk.

The villagers of Lakardowo Mojokerto, Java East used to go in secret to the office of environmental organisation Ecoton. Riska, the youngest member of Ecoton, remembers the first contacts of the villagers with her team of militant biologists. It will take some years, ill children and whistle blowers to realise that the bricks are one of the products into which the plant gets rid of toxic waste. Today all around the village are still standing these low walls of greyish brick, down market material for poor rural people. Juwita is the mother of a child who has been suffering serious dermatological disorders for the last three years. She claims the illness of her child comes from the water quality. Before the plant arrived, she could drink the water, now it must be boiled. Every household in Javanese countryside has a well providing the necessary water but she now seeks other sources of water, for drinking and for bathing.

Production Mapping provides tools for managing your production from beginning to end. Each organization has workflows that are unique to the type of data being collected and the type of product being delivered.
This is a step by step guide to creating a current state value stream map, the first step in working towards your ideal state value stream and a truly lean system. Your current state value stream map is a team effort that is conducted by those people who are involved in the process, at the actual process, not by an expert locked in a room with a pile of procedures. Your Value stream map is a representation of the flow of materials from supplier to customer through your organization as well as the flow of information. This enables you to see at a glance where the delays are in your process, any restraints and excessive inventory. Your current state map is the first step in working towards your ideal state for your organization. Value stream mapping VSM is a team exercise and should involve representatives from all of the areas within the process being mapped, this process should be facilitated and led by an expert with experience in creating value stream maps. A value stream map is best created by hand using a pencil you will need to make frequent corrections and changes on a sheet of A3 paper. It is better to create by hand and involve the entire team in its creation rather than have an expert take the information and return later with a finished map! Firstly we need to decide what it is exactly that we wish to map, in a company with many products there may have to be some initial work done to identify which product or family group of products that should be mapped, we may decide to go with highest volume or value, or take a longer term strategic look at those product ranges that we expect to do more business with in the future or we may be guided by our customers as to what to map. It may not be necessary to analyze all products, use a Pareto analysis to decide which products you need to analyze either through volume or value or a combination.
