The main operational functions of packaging are: containment, protection/conservation, promotion of the product and/or linking a message, i.e. packaging is almost a part of product marketing. In the automotive industry, the packaging developed serves as a means of packaging and transport ensuring the integrity of the product within the supply chain, at the best cost and within the established deadlines. This paper discusses how Quality Function Deployment (QFD) proves to be an effective methodology for ensuring success in automotive packaging development. The study is delimited to the development of packaging at a vehicle manufacturer in the southern region of the state of Rio de Janeiro. It is expected that the House of Quality, the first stage of the QFD method, presented in this article and used by the packaging development sector, can attract more teams and organizations to adopt QFD in the development of packaging, identifying, and meeting the needs of the company's internal customers and guiding external suppliers in the development of this packaging, aiming for better quality and lower cost packaging.

“…The methodology of design of experiments was first applied in agricultural experiments, and quickly became used in the fields of engineering, biology, chemistry, and environment. In recent years, there is a constant concern among researchers to statistically prove the validity of laboratory experiments (Cardoso, Reis, Silva, Barros, et al, 2023;Dal Molin et al, 2008;Fonseca et al, 2023).…”

This study aimed to present one of the applications of complete factorial planning with significant interactions as well as Tukey's Test in the agricultural and environmental area. To achieve this objective, applied research of exploratory nature and quantitative approach was carried out. As method and technical procedures were adopted, respectively, the bibliographical research, the literature review, and a case study. As a contribution of this research, it is pointed out the use of this tool in other research fields, but mainly in the environmental area.

“…As an example that occurs a plasma etching process for the fabrication of integrated circuits. During fabrication, a mask of the tracks is drawn on a printed circuit, and the factors influencing this process are Distance, which ranges from 1 cm to 1.4 cm, and Power, which ranges from 350 W to 400 W. The response variables are the Engraving Rate in (Å/m), which must be maximized to get the best response in the process, and the Uniformity in (Å/m), which must be minimized to get the best response in the process (Fonseca et al, 2023). This problem was described in the book by Montgomery;D.…”

A problem facing the product development community is developing simultaneous solutions of response variables (to several properties) that depends on a number of independent variables or sets of responses. Harrington, among others, addressed this problem and presented a desirability function with a functional approach. Derringer and Suich altered their approach and illustrated how multiple variables can be transformed into a convenience function. This work redid the calculation performed by them using another software and made a comparative discussion of the results found.
