QFD AND TRIZ IN PRODUCT DEVELOPMENT LIFECYCLE
Andreea Ionica, Monica Leba, Eduard Edelhauser

ABSTRACT.The "life" of a business starting from its birth time passing through the growing period and reaching maturity is strongly related with the course of its products, also known as product development life cycle (PDL). The research represents an approach that integrates in PDL the Quality Function Deployment (QFD) and the Theory of Inventive Problem Solving (TRIZ) methods, as a tool that can help companies to successfully develop new products or to improve the existing ones through a series of innovation-related steps, starting from the process of idea generation and ending at the launch of the product into the market. In order to validate the research results we present a case study that explores the application of our methodology on a programmable controller for the mining extraction machine. The conclusions emphasize the applicability of the proposed methodology, a useful tool in business innovation for adapting to the current competitive market.

KEYWORDS: innovation, spiral model, quality management, mining product application.
