    The House of Quality Worksheet

    The House of Quality worksheet is the main worksheet of the QFD1 component. It shows the QFD1 matrix together with benchmarking tables and the inter relationship matrix of the CTQs / Functions.

    1. 1
      VOC - Voice of the Customer: hierarchical structure of system and customer requirements. Collect all requirements based on customer benefit. Build a structure of groups and sub-items.
    2. 2
      Importance rating for VOC. Created by one of the available prioritization methods, e.g. AHP.
    3. 3
      VOC Benchmarking
      How good does the listed product (column) meet the customer requirement (row)?
    4. 4
      CTQ / Functional Requirements
      CTQ - critical to quality. This is the hierarchical structure of product functions and critical technical requirements. Collect all technical requirements defining the quality of the product functions. If possible, place technical requirements inside a product function. Use and to change functions into CTQ or vice versa. Use ConstraintConstraint on technical specifications that cannot be optimized, e.g. technical standards.
    5. 5
      FR Specs
    6. 6
      QFD Matrix
      Does improving the Functional Requirement help to better satisfy the VOC need?
    7. 7
      CTQ Importance
      Importance ratings for CTQs and Functions calculated from VOC Importance and QFD 1 Matrix.
    8. 8
      The roof of the House of Quality documents conflicts and synergies when improving CTQs.
    9. 9
      CTQ Benchmarking
      Enter all measurements taken from the real products.
    10. 10
      This table contains specifications for functions and CTQs, e.g. unit and targeted value.
    11. 12
      VOC Quality Plan
      This table is an add-on to the benchmarking table. It computes a suggested target value for your new product depending on current performance, competitor performance, and importance of each requirement.
