How do you learn value stream mapping?

How to draw a value stream map

1. Determine the scope of your value stream map. Create your start and end points first, and place them in the top left and right corners of your document.
2. Map the steps of your process.
3. Add inventory and wait times.
4. Designate the direction of information flows.
5. Create a timeline.

What is value stream mapping PDF?

Value Stream Mapping involves process flows, communication flows and material flows from the point of raw material to the delivery of product to customer. This paper presents how value stream mapping can be used in manufacturing firms for improvement of overall production process.

What is C T and C O in VSM?

• Customer demand. • Cycle time (C/T) • Process time (P/T) • Changeover time (C/O)

What are the five principles of value stream map?

The five principles are considered a recipe for improving workplace efficiency and include: 1) defining value, 2) mapping the value stream, 3) creating flow, 4) using a pull system, and 5) pursuing perfection. The next sections provides a detailed overview of each principle.

What is the first step in VSM?

The first step in value stream mapping is to create a current state map. This map can help identify waste such as delays, restrictions, inefficiencies, and excess inventories. These are then eliminated in the ideal state map, which gives the organization a working plan to achieve lean efficiency.

What is the next step of VSM?

The next step before VSM is to construct a process quantity routing analysis to identify product families according to a similar build sequence. With this information, you will know exactly what you are mapping through the flow of your operations.

What does C O stand for in VSM?

Change over (C/O) can be used to log how long it takes to change over from one product in the product family to another. Batch can show how many products are worked on at the same time, and EPEI (every product every interval) can show the maximum lead time for on product within the family.

Is VSM a lean tool?

Value stream mapping (VSM) is defined as a lean tool that employs a flowchart documenting every step in the process. VSM is an essential lean tool for an organization wanting to plan, implement, and improve while on its lean journey.

What is C o in value stream mapping?

In this case, the definition of a C/O is the total time between the last good A and the first good B. So the total time between this is in fact the C/O. As it relates to VSM… we normally note this C/O time for that process as you suggest.

What are the 5 key lean concepts?

According to Womack and Jones, there are five key lean principles: value, value stream, flow, pull, and perfection….Five Key Principles

• Value. Value is always defined by the customer’s needs for a specific product.
• Value stream.
• Flow.
• Pull.
• Perfection.

How do you analyze a value stream?

Value Stream Mapping in 7 Steps

1. Document the current process.
2. Identify and list every step in the process.
3. Identify customer value.
4. Define what the perfect process looks like.
5. Identify those parts of the current process that get in the way of perfection.
6. Identify major initiatives to reduce or eliminate waste.
