  • Steps in filing up the HOQ and its calculations Research or perform customer survey to develop a list of Customer Quality Requirements Example: a training book should be: easy to use, accurate have clear design, be brief Identify importance to customer for each of the customer requirements Asses company competitive performance based on customer requirement Identify how your product offering measures against competition then score on a scale 1-5, 5 being the best The company evaluation is shown in black line and connects the existing position of the company Prioritize Customer Requirement Set target values for improvement. These values should be made while considering the sale potential!! => give or assign whished stage The target values are highlighted in blue Calculate absolute weight for each opportunity A full calculation of the absolute weigh for customer requirement for this HOQ is presented on the next slide Based on customer requirement develop list of technical requirements that create a desired product Example: for the training material it should have: clear formatting style, timely renewals, good coverage of topics, good graphics, understandable word choice, table of contents Asses relationships between customer requirement and technical needs Identify correlations between customer requirement and technical requirement and scale the relationship 1= week correlation 3= moderate correlation 9= strong correlation Evaluate technical requirements against competitors Prioritize technical Requirement Set target values for technical improvement and calculate the absolute weight for each technical requirement This values are not presented on the graph!!! Identify Correlations between technical requirements Calculate importance Weighting and Prioritize

    8. 8. Contradictions <ul><li>All systems contain contradictions </li></ul><ul><ul><li>What gets worse as what gets better? </li></ul></ul><ul><ul><li>E.g. strength v weight </li></ul></ul><ul><li>We usually accept a compromise or trade-off, but this is often not necessary </li></ul><ul><li>Ideality = ‘Value’ = Benefits </li></ul><ul><li> Cost + Harm </li></ul><ul><li>Powerful solutions are the ones that don’t accept the trade-offs </li></ul><ul><li>We should actively look for contradictions as there are ways of eliminating compromise </li></ul>

Evolution and Transformation Ideation Way TRIZ restructuring and expansion (I-TRIZ): More power plus simplicity New tools… New Applications: AFD, DE… Complete process computerization Trial and Error: Simplicity, no power Computerization of selected tools Classical TRIZ: Complexity and power Plain simplification: Simplicity minus power Selected simple tools (Contradiction Matrix, etc.)
    13. 13. Inventive Problem Solving Anticipatory Failure Determination A systematic procedure for resolving tough technological problems, enhancing system parameters, improving quality, reducing cost, etc. for current generations of products and technologies. Failure Analysis A systematic procedure for identifying the root causes of a failure or other undesired phenomenon in a system, and for making corrections in a timely manner. Failure Prediction A systematic procedure for identifying beforehand, and then preventing, all dangerous or harmful events that might be associated with a system. Control of Intellectual Property A systematic procedure for increasing IP value and providing protection from infringement and circumvention. IPS AFD CIP I-TRIZ Ideation TRIZ Applications
