How do you create a value stream map?
How to draw a value stream map
- 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.
- Map the steps of your process.
- Add inventory and wait times.
- Designate the direction of information flows.
- Create a timeline.
How is value stream mapping calculated?
Process efficiency In VSM, the ratio of process time (value adding time) to lead time. Calculated by dividing the total process time by total lead time. Also known as flow-time efficiency. Process time Total time required to properly handle an item within a process step.
How do you create a future state value stream map?
Let’s see what improvements we foresee.
- Step 1: Create a Cycle Time / Takt Time Graph.
- Step 2: Decide if you will build to stock or make to order.
- Step 3: Calculate Optimal Crew Size and Implement One Piece Flow.
- Step 4: Pull when One Piece Flow is not Possible.
- Step 5: Improve Communication and Schedule a Pacemaker.
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 is VSM tool?
Value stream mapping (VSM) is defined as a lean tool that employs a flowchart documenting every step in the process. VSM is a workplace efficiency tool designed to combine material processing steps with information flow, along with other important related data.
Why is the VSM important?
Value stream mapping is an important element of lean operations, the goals of which are to maximize customer satisfaction and minimize waste. Operating in this way allows companies to do more with less, offering better value and higher quality to their customers.
What is Gemba approach?
A popular approach in companies who implement lean principles is called “Gemba walks,” which denote the action of going to see the actual process, understand the work, ask questions, and learning from those who do the work (showing respect to them).
What are the 8 Wastes?
The 8 wastes of lean manufacturing include:
- Defects. Defects impact time, money, resources and customer satisfaction.
- Excess Processing. Excess processing is a sign of a poorly designed process.
- Non-Utilized Talent.
What is muda or waste?
Muda translates roughly as waste, and refers to the inefficiencies within processes which you can seek to reduce or eliminate entirely. In effect, lean declares war on waste – any waste. Waste or muda is anything that does not have value or does not add value. Waste is something the customer will not pay for.
What Gemba stands for?
Genba (現場, also romanized as gemba) is a Japanese term meaning “the actual place”. Japanese detectives call the crime scene genba, and Japanese TV reporters may refer to themselves as reporting from genba. In business, genba refers to the place where value is created; in manufacturing the genba is the factory floor.
What is Gemba Gembutsu Genjitsu?
When combined together, gemba, gembutsu and genjitsu can be an extremely powerful continuous improvement strategy. It involves having the managers go to the actual shop floor (gemba) looking at the actual products involved (gembutsu) and gathering as many facts about the situation as possible (genjitsu).
How do you do the virtual Gemba walk?
How (and Why) to Walk the Gemba When Everyone’s Working from Home
- Keep the Purpose in Mind.
- Incorporate Video Conferencing.
- Focus on Process, Not People.
- Follow the Standard Process.
- Do Not Implement Changes During the “Walk”
