  4. 4. The fuzzy front end of product innovation processes : the influence of uncertainty, equivocality, and dissonance in social processes of evolving product concepts

    Författare :Sven Andersson; Luleå tekniska universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovations; Fuzzy front end; Business Economics - Business studies; Innovationer; Ekonomi - Företagsekonomi; Accounting and Control; Redovisning och styrning;

    Sammanfattning : Developing new products is essential for the long-term survival of companies. The fuzzy front end (FFE) is the first phase in the product innovation process and is considered an important determinant for successful product innovation. This thesis addresses the social process in which individuals evolve a product concept in the fuzzy front end. LÄS MER
