## What is the output in VSM?

The output of value stream mapping, value stream maps, provides a picture of the entire work processes, showing both value and non-value adding activities. Instead of taking a haphazard approach to lean implementation, value-stream maps enables a more systematic and sustainable approach.

**What is value stream ratio?**

What is the Value Added Ratio? The value added ratio (VAR) is the time spent adding value to a product or service, divided by the total time from the receipt of an order to its delivery. A less expansive variation only includes in the denominator the period from the beginning of production or service through delivery.

**How is value stream mapping measured?**

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 do you complete value stream mapping?

Value Stream Mapping in 7 Steps

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

**What is the formula for calculating lead time?**

Lead Time = Supply Delay + Reordering Delay First, you need to determine what your supply and reordering delays are. As their names imply, a supply delay is how long a shipment takes to reach your warehouse, while a reordering delay is the amount of time it takes for a supplier to accept and replenish your order.

**What is a value stream example?**

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.

## What does the activity ratio measure in the value stream?

The activity ratio is a good gauge of how much time work is sitting idle in a value stream. As a result, it is a solid measure of flow. The higher the ratio, the better the flow.

**How do you calculate C & A?**

Percent Complete and Accurate (%C&A or %C/A) This metric reflects the frequency of complete and accurate information received for processing. Calculate this as simple percent of total. % C&A = (# Complete & Accurate / Total) * 100 Collect during process discovery.

**How do you find the percent added value?**

Subtract the original value from the new value, then divide the result by the original value. Multiply the result by 100. The answer is the percent increase.

### How do you calculate percent complete and accurate?

**How do you calculate rolled percent complete and accurate?**

Determine the Percent Complete & Accurate (%C&A): For each step, ask what percent of the product/work-in-process is complete and accurate when first received. This is the %C&A. Multiply those values together to get the rolling %C&A for the entire process.
