2 DGQ Fachtagung 56 th EOQ Congress FQS Forschungstagung Walter Masing Award 2012: Metrological System for Perceived Quality Parameters to Establish Transfer Functions to Human Perception

3 Customer Relevance of Perceived Quality (JD Power) Overall Appeal Score Importance* * Differs by Market and Segment Page 3

4 Introduction What is Perceived Quality?... is the human based evaluation of a product by the sensory inputs cross linked with expectations, experiences, preferences, and cultural factors. Page 4

5 Why do we measure Perceived Quality? Motivation: We can only methodically improve, what we can measure in a robust and reliable manner Efficiently handle communication during the whole product creation process between: Design, Product Development, Supply Base, Launch Team, Manufacturing and vice versa. Page 5

6 Creation of a Perceived Quality Function Measurement of Perceived Quality Attributes Correlation Acquisition of Human Quality Perception... Y = f (x1, x2, x3, ) Page 6

7 How to Measure Perceived Quality Switch Feel - Force Profile - Torque Profile - Wobble -Friction - Usage Stereotypes - Switch Sound - Switch Harmony Robotized Unit for Tactility and Haptics Visual Quality - Gaps - Flushness - Gloss - Colour - Graining - Micro Graining - Visual Harmony Surface Haptics/Tactility Orthogonal: Tangential: - Elasticity - Friction & stick-slip (initial & progression) - Roughness (macro & micro) - Recovery Rate - Surface Topography - Stickiness Other: - Surface temperature feel - Stiffness of components - Moving components Page 7

12 How Can We Include the Real Human Perception? Customer do not communicate in form of Engineering Parameters Engineers need measurable quality attributes and parameter as basis for improvements and specifications attractive?? Translator is needed for engineers to better understand the real customer needs
