Value-Add vs Non-Value-Add
Value-Add (VA)
An activity is value-add if it meets all three criteria:
- The customer is willing to pay for it
- It transforms the product or service
- It is done right the first time
Examples: Assembly, diagnosis, treatment, coding, machining, testing
Non-Value-Add (NVA)
Activities that consume time or resources but don't add value from the customer's perspective:
- Waiting — queues, approvals, batching delays
- Transport — moving materials or information
- Motion — unnecessary movement of people
- Rework — correcting defects or errors
- Over-processing — doing more than required
Note: Some NVA is necessary (compliance, safety). Target unnecessary NVA first.
