Many companies have been reorganizing from a sequential to an integrated path known as simultaneous engineering, which aims to reduce development time and costs. The main problem during technology and product development is the integration of the design and manufacturing areas in the product development phase. This paper proposes a model to improve the use of simultaneous engineering by integrating project and manufacturing knowledge areas based on concepts of manufacturing readiness level, design for manufacturing and assembly and technology readiness level. Based on a bibliographic review and a preliminary study conducted over 1 year in a multinational metalworking company, a model was proposed as a method to be applied in the early stages of product development. The results show an integration of proposed engineering areas into a product development process, a cost reduction of 20% and a manufacturing investment reduction of 25%.

许多公司一直在从顺序重组到集成路径，称为同步工程，旨在减少开发时间和成本。技术和产品开发过程中的主要问题是产品开发阶段设计和制造领域的整合。本文基于制造准备水平、制造和装配设计以及技术准备水平的概念，提出了一种通过整合项目和制造知识领域来改进同步工程使用的模型。根据文献综述和在一家跨国金属加工公司进行的一年多的初步研究，提出了一种模型作为在产品开发的早期阶段应用的方法。
