Abstract
Purpose
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.
Design/methodology/approach
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.
Findings
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.
Research limitations/implications
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.
Originality/value
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.

Abstract
Purpose
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.
Design/methodology/approach
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).
Findings
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.
Originality/value
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.

Abstract
Purpose
This research analyzes the current knowledge regarding the use of maturity models (MMs) in SSCM, aiming to identify the main characteristics, trends and research gaps on the subject. Facing the growing interest in carrying out studies directed at sustainability, to the detriment of more prescient environmental and social impacts and the need to consolidate the concepts present in the literature regarding the SSCM, an absence of similar studies in the current literature was found. The authors have selected articles to compose a database that allows users to analyze and classify publications on MMs in SSCM, being those subdivided into 7 categories: focus, methodology, analyzed sector, sustainable practices, dimensions of sustainable development, type of MM and model/framework validation method.
Design/methodology/approach
To achieve this purpose, a literature systematization was conducted by searching publications using defined keywords in two databases and following a process of classification. The systematic process has five steps, from the selection of databases to the filtering of publications, review of information and analysis of the sample.
Findings
The topic under study is promising, with a few publications dealing with it, mainly in Brazil, and there is a trend to exploit more of the area in future research.
Originality/value
This research provides a detailed analysis of an emerging theme, divided into seven thematic categories. Results demonstrate that the topic is still underexplored, indicating an important research gap to be filled.
