Five Steps to Implement Lean
1. Specify Value. Identify which features create value. Define value from the final customer.
2. Map. Identify the sequence of activities called the value stream.
3. Flow. Make the activities flow continuously through the remaining value-created steps. Eliminate barriers and develop product-focused organization that dramatically improves lead time.
4. Pull. Letting the customer pull product or service through the process eliminated the need for a sales forecast.
5. Perfect the process. Manage the perfection so that the number of steps and the amount of time and information needed to serve the customer continually falls.
