Methodic Design of a Customized Maturity Model for Geometrical Tolerancing

摘要

Challenges for today's organizations and their development processes are designing faultless reliable products within shorter development times and low resource consumption. The additional higher complexity of the products to be designed causes a low transparency of the development status, whereby decision-making and problem-solving become more difficult. In order to persist in a global competition, increasing effectiveness and efficiency of the development is elementary. Maturity models represent Best-Practices for a specific approach and can uncover improvement potentials in development by evaluation of defined indicators. A new approach is proposed, which allows designing customized maturity models systematically for a subject matter. By the resulting base of indicators the status of the subject matter can be determined to deduce specific operational improvement measures. The method for the design of a customized maturity model is exemplary applied in the field of geometrical tolerancing. With the help of a principle approach for the geometrical tolerancing maturity relevant indicators like “Tolerance specification” or “Validation of specification” are elicited and sub- divided into their characteristics. Requirements on these characteristics are staged and assigned to four maturity levels. The result is an evaluation basis, which allows to assess the performance of tolerancing work and to deduce improvement measures.
