Abstract (Susan ne Ellebrecht)

Application concept of combined preventive quality management methods in inter-enterprise health management of pork chains

Overall, this thesis aimed at establishing a concept to organize and evaluate services ininter-enterprise health and quality management with the help of team-oriented preventivequality management methods in a new and more efficient form. ln this context, the question

was addressed to which extent existing service offers still meet the actual customerexpectations of farmers. Furthermore, it was of interest to find out which quality management

methods are already known to the service providers of the sector and are integrated into their

teamwork. Answering these research questions was a precondition for assessing thedevelopment potentials of future service offers and service organizations in inter-enterprisehealth management.

This methodology to develop an application concept for team-oriented quality managementmethods for such service providers was subdivided into six different phases.

While the firsf three phases (literature study, written enquiry (206) and 55 expert interviews)

covered data collection, in phase four a proposal was made how to proceed with theexpansion of network coordinators' service portfolios. When doing this, the categorization ofproducts and services used by Kano served as a basis. Phase five included development of

an application concept with preventive quality management methods. Subdivision of quality

management methods into the relevant partial steps and merging these into a methodologyenabled allowing for characteristics belonging to selected methods combined into oneconcept. The final phase 6 included development of a structural equation model on the basis

of the established findings visualizing causal relations between defined factors and thequality of coordination services. This model included seven latent variables, 16 formative and

three reflective indicators.

ln a diagram consisting of four quadrants ("QM+CS Stars", "CS Freeloade/', "QM Question

Marks" and "QM+CS Dogs"), it was possible to subdivide the network coordinatorsquestioned into three clusters regarding the offer of services in inter-enterprise healthmanagemenf (CS) and the use of qualtty management methods. The compiled applicationconcept for quality management methods supports development of network coordinatorsregarding the use of quality management methods towards "QM+CS Stars" by integratingpartial steps of quality management methods into the normal operations of enterprises. ln

contrast to this, the modified Kano categorization enables to optimally consider customerexpectations when expanding service portfolios. For example, services not demandeddirectly by farmers but which provide them with an enormous added value are classified as

"attractive services". ln addition to this, the causal relations demonstrated in the structural

equation model regarding the quality of coordination services serve to increase the quality of

existing and new services and thus to optimally satisfy customer expectations.
