Contribution for Analysing, Saving and Prioritising of Lessons Learned Issues Regarding Product Improvement and Future Product Generations

Based on the customer's product recognition, environment protection becomes key sales arguments within the consumer goods industry. Customers expect longer usage phase of products and reduced use of resources. Product reliability may help to save resources in many ways such as replacement of parts and minimizing logistic efforts throughout the product's life span. To achieve the generic goal of reliability and sustainability, it is important to learn from product's failures during design, manufacturing and use phase. Therefore, structured knowledge regarding a long life cycle (e.g. development: 2 years; production: 6 years; usage: 15 years) should be saved. This paper outlines a conceptual Lessons Learned approach on how to analyse, save and prioritise Lessons Learned issues – based on structured weak point data and information - out of the product life cycle to improve reliability and sustainability of the subsequently product generation.
