Value-Added Flow Analysis Tool
Classify every process step as value-added, necessary non-value-added, or waste, and tag each waste step by type. The tool computes a live value-added ratio and a breakdown of time lost by waste category, pairing directly with the 8 Wastes guide.

How to Use This Value-Added Flow Analysis Tool
List every step in the process in order, with its observed or estimated time in minutes. Classify each step as Value-Added, Necessary Non-Value-Added, or Waste. For any step classified as waste, select which of the 8 Wastes it represents. The tool computes a live value-added ratio and breaks down waste time by category.
Classification Guide
| Classification | Test |
|---|---|
| Value-Added | Physically transforms the product or service, done right the first time, and the customer would pay for it |
| NVA (Necessary) | Does not add customer value but is currently required, such as a compliance check |
| NVA (Waste) | Adds no value and is not required; a target for elimination, mapped to one of the 8 Wastes |

FAQ
What counts as value-added?
A step is value-added only if it physically transforms the product or service in a way the customer would pay for, is done right the first time, and is done in a way the customer cares about.
What is necessary non-value-added work?
Necessary non-value-added work does not add value in the customer's eyes but is currently required, such as a regulatory inspection or a required approval step. It is a target for reduction, not elimination, unless the requirement changes.
What is a good value-added ratio?
There is no universal target, but most unimproved administrative and transactional processes run well under 10% value-added time. Track the ratio over time as a directional improvement indicator rather than chasing a specific number.
Can I export the analysis?
Yes. This tool supports print or save-as-PDF, Word-compatible HTML, Excel-compatible spreadsheet output, Google Docs-compatible HTML, and Google Sheets-compatible CSV.
