Although nearly all processes deal with some information, transactional value streams deal primarily with information , unlike manufacturing value streams which deal with materials, or healthcare value streams which are centered on patients.
What is value stream manufacturing?
The “value stream” identifies all the actions and steps that a product takes throughout a manufacturing process , starting with obtaining raw materials all the way to final delivery of a product. ... It's important to map out the entire manufacturing process, including: Cycle times. Down times. In-process inventory.
What is the difference between value stream and process?
The value stream level focuses on looking at work across organizations, functions and processes . The process level focuses on looking at work within a process, function or department. The task level focuses on looking at how the steps are performed within a process.
What is one of the primary differences between a value stream map and a process map Mcq?
“The biggest difference is that value stream mapping is focused on driving process change , while process mapping, mining and discovery are well-suited to making existing processes more efficient,” said Sylvie Thompson, associate partner of the digital supply chain practice at Infosys Consulting.
What improvement does a value stream map typically provide?
Value stream mapping provides a visual representation of the flow of materials and information throughout the organization . It helps to identify, demonstrate, reduce waste and finally create effective flow through all the processes in the manufacturing organization.
How do I use VSM?
- 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.
What is a process value stream?
VSM is a workplace efficiency tool designed to combine material processing steps with information flow , along with other important related data. VSM is an essential lean tool for an organization wanting to plan, implement, and improve while on its lean journey.
What is the first step in the VSM?
The value stream mapping process. The first step in VSM is the selection of product family with common features or similar processes to avoid complexity . Then, the current state map showing the current process is drawn.
What is the first step in VSM Mcq?
The first step in VSM is the selection of product family with common features or similar processes to avoid complexity . Then, the current state map showing the current process is drawn.
How is VSM 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. ... For simple processes, the cycle time and the process time can be used interchangeably.
What is the benefit of value stream mapping?
The purpose of a value stream map is to view the entirety of a process flow from start to finish and create a plan to optimize efforts in getting the company to its desired outcomes . By illustrating the current state, a value stream map allows you to know where there are current gaps.
What are the disadvantages of value stream mapping?
Disadvantages. There is somewhat of a learning curve to creating a VSM framework . It often requires a substantial investment of time and money initially, and if not prepared correctly can become a source of wastage in itself.
Why do a VSM?
The purpose of a value stream map is to view the entirety of a process flow from start to finish and create a plan to optimize efforts in getting the company to its desired outcomes. By illustrating the current state, a value stream map allows you to know where there are current gaps.
What is an example of a value stream?
Operational value streams (OVS) are the sequence of activities needed to deliver a product or service to a customer. Examples include manufacturing a product, fulfilling an order, admitting and treating a medical patient, providing a loan, or delivering a professional service .
How does a value stream map help to identify waste and eliminate it?
Value stream mapping is the process of identifying bottlenecks, waste, and value-added steps within a flow of material and information. The value stream map is the appropriately named tool used to present and analyze the information uncovered by looking deeper into an organization's processes .
What are two types of value streams?
There are two types of value streams – operational value streams and development value streams .
