1. Value adding (VA), Non-value adding (NVA) work
- Only those activities that meet the 3 basic criteria can be considered Value adding:
- customer is willing to pay for the activity
- the activity physically changes the product or the information necessary for production
- the activity is performed 'First time right'
2. Production flow and Waste elimination
The processes need to be set up in a way so that the products spend the maximum time in VA activities and the minimum in NVA.This can be achieved through elimination of the 7 sources of waste:
3. Employees engagement and continuous improvement
To engage employees is critical from multiple reasons. The people involved in planning and implementation will be more likely to adopt and support the changes. Moreover, the real experts on every task are most often the people who perform the actual job.
No process can be set up perfect in one go so that no improvement or modification will ever be required. Only by reaching the changed state you will be able to see the next possible improvements.
Organizations that manage to institutionalize improvements as a normal way of everyday life are in the best position for a long term success.
