The first task is a thorough review of how the packaging are constructed currently. You should choose 2-5 packaging which have been constructed during the recent year. You go through the entire decision process and identify decision makers and how the decisions are made. Find out whether actual calculations or analyses have been made and whether they have been documented. We recommend that you work through the entire process. Often essential considerations have been made by persons or departments situated far from the packaging development. However, this documentation has seldom reached the packaging constructors.
