Implementing VITAL

Summary

  • To enable multi-disciplinary design teams

  • To visualise the external aspects of an automobile

  • Within a realistic model of the physical environment

  • At conceptual design stage

Summary

  • Can loosely be defined as the “Look” of the product.

  • How can Cosmetic Quality be consistently assessed when it has no agreed definition?

  • Considers Gap and flushness.

  • Can dramatically affect customer perception of the product.

Implementing VITAL

Summary

  • Investigate the implementation opportunities of such technology within both published and applied design/development processes.

  • Compare general published design process models with those applied within the automotive industry.

  • Consider the potential cosmetic quality improvements and business benefits of such technology.

Summary

  • Two automotive companies targeted for case studies

    • Rover

    • Jaguar

  • Investigate the automotive design/development process adopted in terms of,

    • The stages of the process

    • Roles and responsibilities

    • Information flows

    • Related component/design sub-processes

    • Departmental structure

Summary

Compare applied design process models (Jaguar & Rover) with accepted design process models.

  • Similarities, irregularites

  • Where and when is cosmetic quality assessed

  • Stages, tasks where VITAL could be applied

Summary

Evaluating VITAL highlighted the following issues:

  • Concern about the number of processes & software tools that would be needed to be integrated.

  • How and where would these processes and tools would be integrated within the automotive design/development process.

    MPhil study should:

  • Recommend an implementation plan for VITAL.

  • State the areas where VITAL will impact upon in order to drive product cosmetic quality.

Summary

The potential benefits of VITAL are:

  • Business Case

    • Design process impact

      • Shortened lead times

      • More centralised design teams

      • Earlier consideration of tolerances

    • Reduced costs

      • Less design re-work

      • Less physical prototypes

    • Training, process re-organisation

  • Cosmetic Quality

    • Customer Perception

    • Higher Build Quality

Summary

QZ - ‘Qualitats Zahl’ - Zero Quality

  • Assess the car from the customers point of view.

  • Make the designer think about quality from the beginning of the design process

  • QZ involves attaching a score to the vehiclebeing audited. It is a representation of thelevel of quality.

  • It should be applied as early as possible in the

    design process.
