1 What is value stream mapping?
Value Stream Mapping (VSM) is a simple, yet powerful Lean technique used to visualize and analyze the flow of materials / processes and information through mapping. output mapping, value stream maps, gives a picture of the whole process work, showing both values and non-value adding activities. Rather than taking a haphazard approach to lean implementation, VSM allows more systematic and sustainable approach. VSM is also sometimes called a road-map or plan for lean transformation.
VSM looks full, end-to-end process using a simple visual icons. This allows visualization of both material and information flow through all activities that occur from the time the order is placed, at the time of the product or service is delivered. It starts with customer needs, demonstrates how and when he got the information, to the end where the product or service is delivered to the buyer, as well as the flow of information and communication processes affecting the whole course.
By looking at the whole end-to-end process, VSM identifies non-value added steps and bottlenecks, allowing for the systematic elimination of waste. value stream maps have become the foundation for improvement initiatives to eliminate non-value, affordable activities.
2 What is the history of the VSM?
VSM comes from car manufacturers Toyota, where they call it the material and information flow mapping. It has been pioneered by Taiichi Ohno, Shigeo Shingo in. However, this is Mike, and John Rother of the earthquake that made the technique popular in the world through his book Learning to See: Value-stream mapping to create value and eliminate muda
.3 How to Value Stream Map is different from other mapping techniques such as business process mapping, flow charting and layout diagram?
VSM is a graphical representation of the process material and information flow, along with key data. It differs significantly from tools such as business process mapping, flow charting or layout diagrams because it includes information flow and material flow. VSM is usually drawn in the opposite direction, from user to stream to the suppliers. need for genuine and real time data collected from the ground is important in VSM compared to other techniques for mapping the value stream map will be useful. This is because the actual ground data is usually shockingly different from the estimated or calculated executives who think they know the data on their finger tips.
4 What are the steps involved in value stream mapping?
Step 1 - Identify the target product, a family of products or services
.2 Step - Drawing the current state value stream map, which shows the current steps, delays and flow of information necessary to deliver the target product or service. This may be the production flow (raw material to consumer) or the design flow (concept to launch
Step 3 - Analysis of current state VSM in terms of creating a flow of waste removal
.4 Step - Draw a future state VSM
.Step 5 -. Implement the future state
5 VSM is applicable to non-production?
While VSM is often associated with manufacturing operations, can be used in any industry or environment to identify opportunities for improvement. It has been used with great success in areas such as:
- services such as banking, finance and hospitality,
- Logistics and supply chain,
- Health,
- Maintenance Repair Overhaul operations for the automotive, aerospace and marine industries,
- Software and product development.
- Government and military
- Administrative and support functions of the organization, such as sales, accounts, customer service and human resources (both manufacturing and service industries ).
6 Is it better to use paper and pencil or software for mapping the value stream?
is to create maps with minimal delay, while observing the target process in the situation. Therefore, the value stream maps are usually drawn by hand in pencil to a simple process mapping and enable easy and quick correction. Using software on the initial phase of VSM is not recommended. Paper, pencil and post-it tag has been recommended from the initial draft finalized by the end of the map.
Having confirmed ticket with all information and data, software tools can be used to digitize for easy storage and formal presentations, although it is not necessary. Most companies, however, still prefer to leave the map the value stream on their walls in their original form and update it as and when required.
7 How long does it take to learn and master skills VSM?
This is the last 2 days to learn but a lifetime to put on the master. There is no short cut to learning and mastering the skills of value stream mapping, the only way is to practice this!
