16 Questions
What is the primary purpose of value stream mapping?
To identify issues and opportunities for improvement
What is the recommended approach to collecting data in value stream mapping?
Collect data in sequential order, following the flow of the process
What type of icon is used to represent inventory in a value stream map?
Inventory Icon
When creating a value stream map, what should be the starting point?
Start with the customer and work from right to left, then left to right, and back up to the customer
What type of data should be collected when creating a value stream map?
Data on resource, time, and quality-based aspects of the process
What is the primary goal of analyzing a value stream map?
To identify bottlenecks and areas for improvement
When should a value stream map be used?
When there are issues or bottlenecks in the process, for continuous improvement, and for brainstorming and idea generation
What is the purpose of using arrows in a value stream map?
To indicate the type of information being communicated
What is the significance of walking the value stream from start to finish in value stream mapping?
To understand how the process truly works from start to finish and to identify issues and opportunities for improvement.
What is the purpose of using icons in value stream mapping, and what are some examples of these icons?
To visually represent the process steps, inventory, and information flow. Examples include customer/supplier, shipment truck, process step, and inventory icons.
How does creating a value stream map from right to left, then left to right, and back up to the customer contribute to the mapping process?
It ensures that the entire process is considered, and that all process steps and information flow are accounted for.
What types of data should be collected when creating a value stream map, and why are they important?
Resource-based, time-based, and quality-based data should be collected. These data are important because they provide a comprehensive understanding of the process and help identify areas for improvement.
What is the primary benefit of using a value stream map to identify bottlenecks and areas for improvement?
It allows for focused efforts to improve the process, resulting in increased efficiency and effectiveness.
How can a value stream map be used to brainstorm and generate ideas for process improvement?
It can be used to create a future state value stream map, which helps to identify potential improvements and opportunities for innovation.
What is the significance of identifying the root causes of issues when using a value stream map?
It allows for targeted and effective solutions to be implemented, rather than just addressing symptoms.
How can a value stream map be used to understand where issues are stemming from in a process?
It provides a visual representation of the process, highlighting areas where issues are occurring and allowing for investigation and improvement.
Study Notes
Introduction to Value Stream Mapping
- Value stream mapping is a tool used to improve processes and understand how things truly work from start to finish.
- It's a snapshot of the process, highlighting issues and opportunities for improvement.
Ground Rules for Value Stream Mapping
- Walk the value stream: start at the beginning of the process and follow it through to the end.
- Collect data in sequential order, following the flow of the process.
- It doesn't have to be perfect, just a high-level snapshot.
Icons Used in Value Stream Mapping
- Customer/Supplier Icon
- Shipment Truck Icon
- Process Step Icon
- Production Control Icon
- Inventory Icon
- Arrow Icons:
- Push Arrow
- Shipment Arrow
- Electronic Information Arrow
- Manual Arrow
Creating a Value Stream Map
- Start with the customer and work from right to left, then left to right, and back up to the customer.
- Identify the process steps, process flow, and information flow.
- Collect data on:
- Resource-based data (batch size, people involved)
- Time-based data (set-up time, changeover time, value-added time, total time)
- Quality-based data (completion accuracy percentage)
Analyzing a Value Stream Map
- Identify bottlenecks and areas for improvement.
- Investigate issues and create projects to improve the process.
- Use the map to understand where to focus efforts for improvement.
When to Use a Value Stream Map
- When there are issues or bottlenecks in the process.
- For continuous improvement and identifying areas for improvement.
- For brainstorming and idea generation, to create a future state value stream map.
- To understand where issues are stemming from and to identify root causes.
Example of Using a Value Stream Map
- A client (Microsoft) orders 200 units of a spark shift book series.
- The process is mapped out, including information flow and process flow.
- Issues are identified, such as:
- Only 25 units in stock.
- Decision to do a revision, which affects the process.
- Low accuracy rate with the supplier (70%).
- Long wait times between process steps.
- Projects are created to investigate and improve these areas.
