This thesis studies the development of the decision-making style at Thailand’s Siam City Cement Public Company Limited (SCCC). The research reviewed the literature, including parent and immediate disciplines. The parent discipline was divided into disciplines 1, 2 and 3. Discipline 1 covered the concept of decision-making and its process. It also assessed types of decisions and summarised the model of decision-making. Discipline 2 looked at organisational structure, decision-making and the locus of decision-making. Finally, discipline 3 focused on group decision-making, group consideration in decision-making and enhancing the group decision-making process.

In the immediate discipline, the key elements that influence Thai’s decision-making styles were discussed. This encompassed Thai societal and cultural characteristics, Hierarchy, organisational characteristics and decision-making. Moreover, research gaps were also explored and the study then proposed four research propositions. The propositions included directing SCCC to develop an appropriate decision-making style based on the group decision-making strategy.

The analysis undertaken was qualitative and employed a case study methodology. The data was collected in SCCC’s Bangkok office between May and September 2002. Data collection was carried out using the Triangulation method. This method employs multiple sources of evidence, including personal interviews, direct and participant observations, documentation and obtaining archival records. The findings confirmed that group decisionmaking should be adopted to enhance the effectiveness of decision-making and efficiency within the firm. Recommendations were also provided for improving practices at the individual, department and organisational level. Finally, contributions to the knowledge, research limitations and areas for further research were discussed.
