This thesis reports on an empirical investigation into manufacturing strategy (MS) formation in practice. The broad objective is to advance the understanding of MS processes through constructing consistent patterns in decision-making and action-taking relating to the manufacturing structure and infrastructure of the organisations studied. Using the "Grounded Theory-Case Study" approach, nine organisations within the metal products, machinery and equipment manufacturing sectors in Australia were studied, in order to address the following research questions: ORIGINALITY STATEMENT 'I hereby declare that this submission is my own work and to the best of my knowledge it contains no materials previously published or written by another person, or substantial proportions of material which have been accepted for the award of any other degree or diploma at UNSW or any other educational institution, except where due acknowledgement is made in the thesis.
