Although there has already been some debate over the role of sustainable product innovation in creating a more sustainable society, it is important to further investigate management methods and factors that influence sustainable innovation capacity. Drawing on the concept of complementarity/the complementary effects perspective, this study aims to analyze the influence of management methods (project management and product development processes) on the development of sustainable product innovation. For this purpose, a survey was carried out with automotive metal mechanical organizations in Brazil, involving a total of 1025 enterprises. This research analyzes the dependency relations between the constructs of Project Management Maturity, Product Development Process Maturity, Product Innovation and Sustainable Product Performance, using the multivariate statistical techniques of Cluster Analysis, Exploratory Factor Analysis and Structural Equation Modeling. The results show a mixture of expected and unexpected findings, which can be summarized as follows: i) the most innovative companies utilize the Project Management Maturity and Product Development Process Maturity constructs more effectively; ii) a combination of complementary management methods enhances the use of resources; iii) companies that take advantage of complementary effects become more innovative and achieve better results in terms of sustainable innovation. Implications for end-users and for theory are also presented.

尽管关于可持续产品创新在创建更具可持续性的社会中的作用已有一些争论，但重要的是进一步研究影响可持续创新能力的管理方法和因素。本研究以互补性/互补效应的观点为基础，旨在分析管理方法（项目管理和产品开发过程）对可持续产品创新发展的影响。为此，对巴西的汽车金属机械组织进行了一项调查，涉及总共1025家企业。本研究分析了项目管理成熟度，产品开发过程成熟度，产品创新和可持续产品绩效之间的依赖关系，使用聚类分析，探索性因子分析和结构方程建模的多元统计技术。结果显示出预期和意外结果的混合，可以总结如下：i）最具创新力的公司更有效地利用了项目管理成熟度和产品开发过程成熟度构造；ii）补充性管理方法的组合可增强资源的利用；iii）利用互补效应的公司将变得更具创新能力，并在可持续创新方面取得更好的成果。还介绍了对最终用户和理论的影响。总结如下：i）最具创新力的公司更有效地利用项目管理成熟度和产品开发过程成熟度构造；ii）补充性管理方法的组合可增强资源的利用；iii）利用互补效应的公司将变得更具创新能力，并在可持续创新方面取得更好的成果。还介绍了对最终用户和理论的影响。总结如下：i）最具创新力的公司更有效地利用项目管理成熟度和产品开发过程成熟度构造；ii）补充性管理方法的组合可增强资源的利用；iii）利用互补效应的公司将变得更具创新能力，并在可持续创新方面取得更好的成果。还介绍了对最终用户和理论的影响。
