You can't manage what you can't measure.
Specific key figures can for instance be used to:
- Document a company’s own packaging efficiency/ optimisation performance over time.
- Document impact or effect of new solutions in packaging design projects as result of an optimisation process, and compare them with existing solutions in the same company, or with similar solutions from other companies.
- Identify which part of the packaging system that are contributing most to loss of packaging efficiency, and which are most relevant for improvement actions
- Communicate with customers, e.g. document and communicate improvement of new product solutions compared to existing solutions
