Firstly, the two groups of manufacturing and service sectors did not demonstrate any significant differences in their measurement models. Therefore, with respect to RQ5, there is no significant differences between the two groups‟ construct validity of the TQM practices. Secondly, the structural relationship models for both groups also depicted no significant differences thus supporting the criterion validity of the relationship between TQM and KM in both sectors. Besides, the results also verified the content of MBNQA conditions which signify the TQM construct across industries, i.e. manufacturing and service sectors in this study. The findings of this study are in agreement with the work of Prajogo (2005). 2

165 Hence, with respect to RQ6, the findings have indicated that there were no significant differences between the manufacturing and service sectors in terms of the causal relationships between TQM and KM practices. Generally, this study has confirmed that the TQM-KM model is robust across different sectors. The robustness is not only limited to its content, but also its significance and deep impact on KM practices in organizations. 7.5 Chapter Summary In this chapter, MGA was performed in order to answer the remaining three proposed research questions, namely RQ4, RQ5 and RQ6. The measurement and structural models have been statistically verified to be invariant across both manufacturing and service sectors through the use of the MGA. The relationships among the items and their respective constructs were also found to be stable or consistent among the two groups. The fit of both measurement and structural models were also found to be very good based on the goodness-of-fit indices. The thorough discussion of the outcomes obtained in this chapter and their impact on the research questions and implications, limitations and future research will be further explained in the final chapter of this thesis, which is Chapter 8.

166 CHAPTER 8 CONCLUSIONS AND IMPLICATIONS OF STUDY 8.1 Introduction In this final chapter, discussion on the findings of the research is provided. This research focused on the field of TQM and the implications of both theoretical and managerial perspectives were gathered. The contribution to the body of knowledge in terms of theory is highlighted. The practical usefulness of the results is presented under the discussion of managerial implications in section 8.3. The research shortcomings in this study are explained and cautioned. Future studies to further improve the knowledge on TQM and KM are also proposed.
