Key figures are important elements in all management systems, as it is in principle impossible to manage activities or processes that are not characterised by some measurable properties (Økstad et al. 2002). Key figures can be used as part of a system for packaging optimisation both for internal decision-making and for external communication. They can thus be of great help for companies in the actual optimisation work.
Does one use more packaging material per packed item? Some key figures can be calculated per product, others can be calculated for the organisation as a whole, for instance the packaging material use in relation to turnover and packaging material cost and logistic cost.
