Product Development and Optimization

This chapter presents four different case studies to cover several concrete situations that experimenters can encounter in the development and optimization phases. The first case study refers to the development of a new sore throat medication, where the research team aims to check the following issues: the mean content of an anesthetic ingredient is not different to the target value of 2.4 mg and the percentage of lozenges with total weight greater than 2.85 mg is less than 40%. In the second case study, two different formulations of condoms have been manufactured and the researchers would like to evaluate the following features: any significant difference in the variability and mean of thickness between the two formulations. The third case study, the Fragrance Project, aims to introduce innovative shaving oil. The final case study refers to a Stain Removal Project that aims to complete the development of an innovative dishwashing product.
