Due to the current and highly competitive industrial scenario, the technology-oriented organizations have been making routine adjustments to the conventional IPDP, in order to seek more profitable business models. Identifying the product functions, as well as its importance - perceived by the consumer - and being able to associate this information with manufacturability and assembly aspects, is fundamental to achieve more competitive, low-cost and higher quality products. This article objective is to evaluate this method concept, applying it in an industrial project. In order to assess the method within the complete integrated product development process (IPDP), the activities related to the conceptual and preliminary phases of the project delineated this article limits. This study selected a subgroup of the white goods industry, where first the traditional models of VE were applied in the conceptual design phase. Subsequently, the classic DFA models were applied in the preliminary design phase. Thus, it was possible to apply the proposed iterative method, where the alternatives generated with the DFA were cyclically re-evaluated, function by function, in the previous stage of value analysis. With this, this study came to the method assessment, its gains and limitations. Then, the original design was compared with the solution after the proposal application, without the method used. Finally, this study verified the influence of the method on the balance between the value and the cost of each function, in addition to the direct comparison of the solution final cost with the version without the method application. Among the results, this article presents a report showing the method viability, its particularities, impacts, and limitations.

由于当前的行业竞争激烈，以技术为导向的组织一直在对常规IPDP进行例行调整，以寻求更有利可图的商业模式。识别产品功能及其重要性（被消费者感知），并能够将这些信息与可制造性和组装方面相关联，这对于获得更具竞争力，低成本和更高质量的产品至关重要。本文的目的是评估这种方法的概念，并将其应用于工业项目中。为了评估完整的集成产品开发过程（IPDP）中的方法，与项目的概念和初步阶段相关的活动在本文中进行了描述。这项研究选择了白色家电行业的一个子类别，首先在概念设计阶段应用了传统的VE模型。随后，经典的DFA模型应用于初步设计阶段。因此，有可能应用所提出的迭代方法，其中在价值分析的前一阶段，逐个函数地循环重新评估DFA生成的替代方案。由此，本研究得出了方法评估，其收益和局限性。然后，将原始设计与提案申请后的解决方案进行了比较，没有使用所使用的方法。最后，除了直接比较使用该方法的版本的解决方案最终成本和解决方案最终成本外，本研究还验证了该方法对每个函数的价值和成本之间的平衡的影响。在结果中，
