Small teams can miss important items, while large teams can end up being difficult to manage and coordinate. The ideal team size is about 10 members.Consider also adding important suppliers to this group because an outside perspective can be helpful. Representatives from multiple departments, such as sales, customer service, inventory, operations, and beyond, will help ensure that information can be passed freely back and forth, and that items don’t slip through the cracks.
Step 1: Form a Team to Create the Lean Value Stream Mapįorm a cross-functional team of high-level managers and supervisors from throughout your company. It is best to start at diagramming a facility level map before attempting to draw a process level map or extended level map so you do not optimize one area and suboptimize another. However, when multiple plants, customers, or suppliers are included, an extended level map is created.Ĭonsider an extended level map as the view of the values stream at 60,000 feet, the facility level map at 30,000 feet, and the process level map at 10,000 feet. This map is a single area in your organization. Understanding the scope of the value stream under examination is a good start when planning your lean process or value stream map. This includes adding features and functionality to a product or service that benefit the customer without increasing wasted time and materials (also called muda, the Japanese term for waste) on the company’s side. The "value stream" portion of the VSM system centers on how value can be added to a product or service by changing the market form or function to meet the customer’s needs. It allowed Toyota to remove nonessential activities that created waste while maintaining the manufacturing process. This VSM illustrated the necessary process steps that existed from order entry to final product delivery and was useful for gaining a wide-reaching view of the company’s activities. The original VSM template was created by Toyota Motor Company and implemented via material and process flowcharts.
Profitable Applications of Lean Value Stream Mapping VSM helps users create a solid implementation plan that will maximize their available resources and help ensure that materials and time are used efficiently. VSM is an essential lean tool for an organization wanting to plan, implement, and improve while on its lean journey. VSM is a workplace efficiency tool designed to combine material processing steps with information flow, along with other important related data. Many lean practitioners see VSM as a fundamental tool to identify waste, reduce process cycle times, and implement process improvement. Value stream mapping (VSM) is defined as a lean tool that employs a flowchart documenting every step in the process.
