  4. 23. Visualizing the Effects of Geometrical Variation on Perceived Quality in Early Phases

    Författare :Ola S Wagersten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometrical variation; geometry assurance; non-rigid; product development; tolerance analysis; variation simulation; visualization and evaluation.; perceived quality;

    Sammanfattning : In a perfect world, geometrical variation in a manufacturing process would not exist. Every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER

  5. 24. Towards good-enough Requirements Engineering : a theoretical Foundation for Requirements Quality

    Författare :Julian Frattini; Daniel Mendez; Michael Unterkalmsteiner; Elmar Juergens; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Requirements Engineering; Requirements Quality; Theory Development; Programvaruteknik; Software Engineering;

    Sammanfattning : Context: Requirements Engineering (RE) research has established a common agreement on the impact that the quality of requirements has on subsequent software development activities and artifacts. Furthermore, empirical investigations suppose that RE quality defects tend to scale in cost for remediation when left unattended. LÄS MER

  7. 25. Towards Efficient Evaluation of Impacts of Geometrical Variation on Perceived Quality in Early Phases

    Författare :Ola S Wagersten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Perceived Quality; variation simulation; visualization and evaluation; Geometrical variation; geometry assurance; non-rigid; tolerance analysis; product development;

    Sammanfattning : In a perfect world, manufacturing would lead to components without geometrical variation. This would mean that every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER
