Every facet of Lean requires knowing where you are starting, and if the changes you make are actually improving the process. For that reason, data collection is a fundamental Lean skill that lays the foundation for successful improvement efforts. Poor data collection sets managers and their teams up for failure. Good data collection makes improvement faster and easier.

This product comes with a corporate license which allows you to share the product within your company only.
The license is automatically assigned to the company name used in the purchase of the product, or if no company included in the purchase, to the company email used in the transaction. If a personal email is used, the license must be manually assigned.
The license is permanent and non-transferable. It is valid only for single reporting units of companies under 20,000 people. For example, that means that a holding company would need licenses for each company in its portfolio.
