The purpose of this paper is to present the application of Design of Experiments techniques for the analysis of operating parameters of an industrial oven for the heat treatment process of polyethylene terephthalate (PET) bottle filaments.

The focus is on evaluating new ways of operating the transformation process. The main issue is to raise what are the variables interfering with the performance of the oven. The complete 2k factorial for three factors of control was used to analyze the behavior of these variables and their relationships in the specific response parameter for the process.

The results presented in this work allow the company to have greater knowledge about the operation of the equipment. The study showed possibilities of 14.8% energy reduction.

The heat treatment activity was characterized as a critical point in the production process, and techniques with empirical approaches, based on statistical techniques, was an opportunity that the company has to improve the execution of activities without major investments for the quality of the final product. The application of statistical quality techniques showed to be very promising.

The fact that the study was conducted using subjective quality performance makes this work different from others presented in the literature, showing the possibility to apply Design of Experiments using main control factors based on the opinion of experienced personnel involved in the process analyzed.

This work investigates the influence of the organizational life cycle (OLC) on the performance management system (PMS) design and the performance of projects in Brazilian industries of software development.

The study employed descriptive statistics and structural equations modeling on the data and information obtained from 115 Brazilian industries of software development with maturity in project management. Data collection was carried out through a survey applied to managers of the organizations mapped and certified by management maturity models Brazilian software process improvement (MPS-BR) or capability maturity model integration (CMMI).

Results revealed that OLC influences the PMS design dimensions (scope, aggregation and opportunity) and project performance. Regarding effects observed on the performance of projects, only the scope dimension's influence was validated by the analyses, and the other dimensions were not significant considering the investigated sample.

The paper shows evidence of how OLC can influence PMS design and project performance. The analyses can help managers to improve their actions in the PMS design, increasing confidence and generating more robust and sustainable results in the business model.
