Abstract
The aerospace industry constantly seeks to optimize its product development processes (PDP) to stay competitive in the market. Design for Excellence (DFX) with its various technological areas, tools and methods play an essential role to allow meeting customer expectations while respecting organizational capabilities. However, the quantity and diversity of DFX technological areas and methods make sometimes difficult to the companies to address the appropriate ones for each project. Success in DFX application, keeping product development (PD) within scope, time, cost, and quality while not overloading it by applying, monitoring, and managing too many areas, is sometimes very context dependent, being influenced by the experience of the engineering team as well as the kind of portfolio project. Considering this scenario, the motivation of this work is to perform a first mapping of the technological areas of the DFX, given the problem of the suitable addressing for each kind of project. The objective is to evaluate, according to the point of view of the engineering team itself, if it is possible to define a general approach to guide, at least initially, project managers in selecting the main technological areas of the DFX, given a typical aerospace organization project portfolio as the boundary condition. Departing from the literature review of the main technological areas of DFX used in the aerospace domain, the research is performed by means of a survey with senior engineers and product development managers from a real aerospace company. Then, quantitative results are gathered through the Likert scale, which allows to draw a hierarchization analysis based on the Analytic Hierarchy Process (AHP) method. The representative example portfolio used in this research comprises the following types of projects: Competitiveness, Operational Continuity, Cost Reduction, Customer Request and Product Reliability & Correction. Results evinced that scope, time, cost and quality have the same weight for the organization whereas Design for Testability (DFT), Manufacturing (DFM), and Reliability (DFR) should be the initial choices for both Operational Continuity and Competitiveness project types.
